Olmsted's Central Park, Capability Brown's England, Kyoto's stone gardens, Burle Marx's curving Brazil, the High Line's elevated reclamation. The art of designing the ground itself.
Landscape architecture is the only design discipline that improves over decades. A garden completes itself in 30 years; a park reaches its character in 50; a designed forest becomes its imagined self in a century. Most landscape architects never see their best work.
The discipline sits between architecture, horticulture, ecology, and civil engineering. It designs the ground — circulation, drainage, vegetation, soil, rock, water — for human use, ecological function, or both. At its best it is invisible, looking like landscape that always was. At its worst it is decorative — fake terrain on top of an unrelated structure.
The professional title was coined in 1863 when Frederick Law Olmsted and Calvert Vaux signed a Central Park report as "Landscape Architects." The word was new; the practice — gardens, parks, country estates, sacred groves — predates agriculture. What Olmsted created was the modern professional discipline: a scaled, evidence-based, civic version of an ancient craft.
This deck covers the long history (Persian paradise gardens, Chinese scholar gardens, Japanese stone meditations, French formal symmetry, English picturesque, Olmsted's American park system, the modern movement, James Corner Field Operations and the post-industrial reclamation, the contemporary climate-driven re-orientation), the major figures, the major sites, and how to look at a landscape and know what is there.
Landscape architecture is not gardening. The disciplines overlap, but their scales and ambitions differ.
Gardening is the cultivation of plants. It is principally horticultural. The garden is what the gardener makes; the framework — bed shape, paths, walls — may be inherited or designed by someone else.
Landscape architecture is the design of the landscape framework. It works at scales from a small urban courtyard to a regional park system. It principally manipulates terrain, water, circulation, and the spatial relationships between plant masses; the actual planting is often executed by horticulturalists or contractors.
The working tools include grading (modifying terrain), drainage (controlling water), planting design (the spatial logic of vegetation), hardscape (paths, walls, structures), and ecology (the systems that sustain the design over time).
The professional landscape architect typically holds a Master of Landscape Architecture (MLA) — the field's standard credential — and is licensed in most US states and many other jurisdictions. The profession is much smaller than architecture (~30,000 licensed landscape architects in the US in 2026 vs. ~120,000 architects), and disproportionately influential — most major civic and institutional projects involve landscape architects from early planning.
The discipline's distinctive intellectual property: the ability to think in slow time. A garden that will look its best at year 40 has to be designed with a clear vision of that future state, while the ground at year 0 looks raw, unfinished, sometimes embarrassing. Most other design disciplines aim at a complete state on opening day. Landscape architecture aims at a complete state half a lifetime later.
The founder of the American profession. Olmsted (1822–1903) had been a journalist (covering the slave South for the New York Daily Times in 1852–54), a farmer, and an administrator (he ran the US Sanitary Commission during the Civil War, the wartime predecessor of the Red Cross) before becoming a landscape architect at age 35.
His pivotal commission: the 1858 design competition for New York's Central Park, won jointly with the English architect Calvert Vaux. The "Greensward Plan" — pastoral meadows, naturalistic woodland, sunken transverse roads, looping circulation, the Mall as a single formal element — is one of the canonical works of 19th-century design and the founding work of American landscape architecture. It opened to partial use in 1859 and was substantially complete by 1873.
The principles Olmsted articulated in the Central Park work and his subsequent practice:
The pastoral as restorative. Olmsted believed (with some 19th-century reformist conviction) that exposure to natural-seeming landscape was psychologically and morally healthful for urban populations. Central Park was meant to be medicine for the city.
Concealed engineering. The transverse roads sunk below grade so park users wouldn't see crosstown traffic; the drainage carefully managed; the planting designed to conceal that it was designed. The art that hides art.
Park-as-system. Olmsted's later commissions — Brooklyn's Prospect Park (1867), the Buffalo park system (1868–98), the Boston "Emerald Necklace" (1878–96), the Niagara Reservation (1885) — were never single parks but networks. The connected-park-system idea became American urban-planning canon.
Olmsted's firm, continued by his sons and stepson, designed thousands of parks, campuses (Stanford, the University of Chicago, dozens of others), residential subdivisions, and the grounds of the United States Capitol. The firm operated until 1979.
The work itself, considered properly. Central Park covers 843 acres (3.4 km²) — a rectangle 4 km long and 0.8 km wide — between 59th and 110th Streets in Manhattan. Olmsted and Vaux's plan is more designed than it looks.
The Sheep Meadow. A 15-acre flat lawn at the south end of the park, originally grazed by sheep (until 1934). The largest open-pastoral space; the canonical American park lawn.
The Ramble. A 36-acre wooded picturesque landscape between the Lake and the 79th Street transverse — the most-naturalistic section. Designed paths wind through what feels like primary forest. (It is not; the Ramble was constructed from quarried rocks, imported soil, and planted trees.)
The Mall and Bethesda Terrace. The single formal axis — a 400-metre tree-lined promenade leading down to the only architectural set-piece, Bethesda Terrace, with its Bethesda Fountain (Emma Stebbins, 1873). The formal element was conceded as necessary; everything else is informal.
The Reservoir. 106 acres of fresh-water reservoir at the centre of the park, decommissioned in 1993 but preserved as the park's largest body of water and its principal jogging loop.
The transverse roads. Four crosstown roads (65th, 79th, 86th, 96th) sunk below the level of park paths so that pedestrian and carriage traffic would not be aware of crosstown traffic. The most original civil-engineering feature of the design and the one that has aged best.
Central Park has been continuously redesigned and restored since 1859 — most ambitiously under the Central Park Conservancy from 1980 onward, which has spent over $1 billion (private money) restoring the park to roughly its Olmsted-era condition after the 1970s deterioration. The Conservancy model — private organisation, public oversight — has been replicated in many other US park systems.
The English 18th-century landscape tradition is the principal precedent for Olmsted's work and one of the most influential design movements anywhere. Lancelot "Capability" Brown (1716–1783) is its central figure.
Brown, gardener at Stowe under William Kent in the 1740s and then independent practitioner from 1751, designed or remodelled over 170 English country estates. His method:
Sweep away formal gardens. The Tudor and early-Georgian English garden had been geometric — parterres, fountains, statuary, allées. Brown ripped them out. The lawn came directly to the front door.
Move earth. Brown's signature was extensive earthwork — recontouring hills, damming streams to create lakes, opening sight lines. Blenheim's serpentine Lake (1764, by damming the Glyme) is perhaps his most-famous single intervention.
Plant in clumps. Trees in informal groups rather than in lines. The boundary between lawn and woodland made deliberately picturesque. The "ha-ha" (a sunken wall, invisible from the house) used to keep livestock out without visible barrier.
Hide the boundaries. The estate appeared to dissolve into the surrounding countryside.
The Brown style — pastoral, expansive, deceptively simple — is the founding aesthetic of the English landscape garden and (through Repton, Loudon, the American transcendentalists, and Olmsted) of the entire pastoral park tradition.
Brown's clients ranged from George III's friends to the Duke of Marlborough. His charged £100,000+ over a career — equivalent to several million in modern terms — and made landscape design a recognised profession in England a century before Olmsted brought it to the United States.
Brown's name (Capability) came from his standard sales pitch: looking over a client's grounds, he would observe that they had "great capability" for improvement.
The deeper European garden tradition.
The Italian Renaissance villa garden. Tivoli's Villa d'Este (Pirro Ligorio, 1572) — sloped terrain, axial symmetry, hundreds of fountains, the Cento Fontane, the Avenue of a Hundred Fountains. Villa Lante at Bagnaia (Vignola, 1568). The Boboli Gardens of Florence (Tribolo, Buontalenti, 1549 onward). The Italian villa garden was hierarchical, geometric, and water-driven.
The French formal garden. André Le Nôtre (1613–1700) is the dominant figure. Vaux-le-Vicomte (1657–61), designed for Nicolas Fouquet — the Sun King attended its opening dinner, immediately had Fouquet arrested, and hired Le Nôtre to expand Versailles on the same principles. Versailles' gardens (1661 onward) cover ~800 hectares; the central axis runs from the palace through the Grand Canal to the horizon. The Le Nôtre style — geometric, dominating, theatrical — became the European standard for absolute-monarchy garden-making, replicated at Caserta (Naples), Peterhof (St Petersburg), Schönbrunn (Vienna), Het Loo (Apeldoorn).
The English shift. Around 1715–1740, English landowners began to rebel against French formality. The shift was partly political (anti-French sentiment, Whig ideology of "natural" liberty), partly literary (Pope's Twickenham garden, the Augustan poets' ideal of the rural retreat), partly horticultural (new ideas about how trees and water actually worked).
William Kent (1685–1748) at Rousham (Oxfordshire, 1738) and Stourhead (Wiltshire, with Henry Hoare from 1741) created the early English landscape garden — designed views, classical follies, picturesque lakes. Kent was Brown's mentor.
The French formal-versus-English landscape debate played out across European garden design for two centuries and is, in some sense, never resolved. Most major modern parks blend both — formal elements at the architectural threshold, informal expansion outward.
The most refined, oldest, and least geometrically simple of the great garden traditions. Japanese garden design has been continuously practised for ~1,400 years and developed several distinct types.
The shinden garden (Heian period, 8th–12th c.). Adjacent to aristocratic residences. Pond-and-island composition viewed from the south side of the residence; designed for moon-viewing, boat parties, and contemplative leisure.
The paradise garden (Heian–Kamakura, 11th–14th c.). Adjacent to Pure Land Buddhist temples. Byōdō-in Phoenix Hall (Uji, 1053). Designed as an earthly anticipation of the Pure Land paradise.
The kare-sansui (dry landscape). Zen Buddhist gardens of raked gravel, stones, and selective moss. Ryōan-ji (Kyoto, ~1500) — fifteen stones in five groups on raked white gravel, viewed from a single platform. The most-photographed Japanese garden and the canonical zen-aesthetic statement.
The tea garden (roji). Adjacent to the tea house. A small, deliberately rustic, transitional landscape — stepping stones, stone lantern, water basin, and a few plants — designed to clear the visitor's mind before the tea ceremony. Sen no Rikyū (1522–1591) is the canonical figure.
The stroll garden (kaiyū-shiki). Edo-period (17th–19th c.) feudal-lord garden. A path leads the visitor through a sequence of designed views — borrowed scenery (shakkei) of mountains beyond the garden walls, constructed islands, tea houses placed for vistas. Katsura Imperial Villa (Kyoto, 1620s, refined to 1660s) — perhaps the supreme example anywhere. Korakuen (Mito, 1629). Kenroku-en (Kanazawa, 17th–19th c.). Kōraku-en (Okayama, 1700).
The Japanese tradition is unusually self-aware. Treatises like the Sakuteiki (the "Records of Garden Making", c.1040, the world's oldest surviving garden manual) articulate principles still taught — the rules of stone placement, the relationship between garden and surrounding landscape, the seasonal aesthetics of moss, of cherry blossom, of autumn colour.
The materials of Japanese garden design.
Stones. Treated as the primary structural element. A garden's "main stone" is selected for character — particular shape, weathering, lichen. Set first; everything else is composed in relation to it. Three-stone groupings (the Buddhist triad: heaven, earth, humanity) are the canonical compositional unit.
Water. Either real (ponds, streams, basins, waterfalls) or implied (raked gravel "rivers" in the kare-sansui). Real water is treated rigorously — direction of flow, sound, reflection, plant interface — with conventions inherited across centuries.
Moss. A defining material in many Japanese gardens. Saihō-ji (the "Moss Temple", Kyoto, 1339) has roughly 120 moss species blanketing the entire 35,000 m² site. Achieving the moss carpet requires constant maintenance — careful watering, leaf removal, fertilising — and is unique to the Japanese climate.
Plants. Used selectively. Pine, maple, plum, cherry, azalea, bamboo, camellia. The plant palette is small relative to Western gardens; each species carries strong symbolic and seasonal weight. Plants are pruned (niwaki) to maintain a designed shape across decades.
Architecture. The garden is always seen from somewhere — a viewing platform, a tea house, a path. The relationship between building and garden is integral; many Japanese gardens are inseparable from the structures that frame them.
Borrowed scenery (shakkei). The garden visually incorporates landscape beyond its boundary — distant mountains, a temple roof, a forest. The perimeter is designed to frame this borrowed view rather than to enclose the garden against it.
The principles transfer poorly to other climates and other plant communities. Most non-Japanese "Japanese gardens" capture some elements (raked gravel, a single feature stone, a tea house) without the deep horticultural commitment that produces moss-carpeted Saihō-ji.
The other great East Asian tradition. Chinese gardens trace continuously to imperial parks of the Han Dynasty (3rd c. BCE); the surviving canon is dominated by the private "scholar gardens" of the Ming and Qing dynasties (14th–19th c.).
The classical Chinese scholar garden was a literary as much as a horticultural construction. The garden owner (a retired official, a wealthy merchant, a poet) designed the garden as a literary setting — sites for entertaining, for poetic composition, for retreat from court life. The garden incorporated calligraphic inscriptions on rocks and pavilions, named individual scenes after classical poems, and was meant to be experienced as a sequence of literary references.
The major surviving Chinese gardens, almost all in Suzhou:
Zhuozheng Yuan (the Humble Administrator's Garden, ~1513). The largest of the Suzhou gardens (5.2 hectares). Originally the residence of an dismissed Ming official; the name is ironic. UNESCO World Heritage.
Liu Yuan (the Lingering Garden, ~1593). 2.3 hectares. Famous for its rockworks, its named pavilions, and its calligraphic inscriptions.
Wangshi Yuan (the Master of the Nets Garden, 12th c., redesigned 18th c.). The most compact of the major Suzhou gardens; the model for the Astor Court at the Metropolitan Museum of Art (New York, 1981, designed by Suzhou Garden authorities).
The Yuanming Yuan (the Garden of Perfect Brightness, Beijing, 1707–1860). The Qing imperial garden, larger than Versailles, destroyed by British and French troops in 1860 during the Second Opium War. The site (the "Old Summer Palace") remains a national wound.
The signature elements of the Chinese scholar garden — irregular pavilions linked by covered walkways, ornamental "gongshi" rocks (eroded limestone from Lake Tai), curving pond, sequenced views — are distinctive and influential. The Ji Cheng treatise Yuanye ("The Craft of Gardens", 1631) is the canonical reference.
The oldest continuously practised garden tradition. The Persian chahār-bāgh (four-fold garden) — a rectilinear walled enclosure quartered by water channels — is the source of the Mughal, Andalusian, and Ottoman garden traditions, and through them of much of European formal gardening.
The earliest evidence: Cyrus the Great's garden at Pasargadae (~540 BCE), where Greek visitors first encountered the Persian word paridaida ("walled enclosure"). Greek transliteration: parádeisos. English: paradise. The garden is the original meaning.
The Persian garden's logic: the four quarters represent the four elements (or four rivers of paradise); the central crossing of channels is the spiritual centre; the surrounding walls separate the cultivated paradise from the surrounding desert. The pavilion at the centre is a place of repose. The whole is irrigated through the qanāt system — underground channels bringing mountain water across kilometres of dry plain.
The surviving Persian gardens — UNESCO collectively listed nine in 2011 — include Bagh-e Fin (Kashan, ~1590), Bagh-e Shahzadeh (Mahan, 1850), Bagh-e Eram (Shiraz, 18th c.), Pasargadae (the archaeological remains).
The Mughal extension: Babur (the founder of the dynasty, who came from Persianised Central Asia) brought the chahār-bāgh idea to India. The Mughal gardens — Shalimar Bagh (Lahore, 1641), the Tāj Mahal complex (Agra, 1632–53), the gardens of Kashmir — are among the world's great gardens. They scale up the Persian model, using Indian water resources and Mughal architectural ambition.
The Andalusian extension: the Generalife (Granada, ~1300) and the Court of the Lions in the Alhambra. Persian principles transmitted through the Umayyad Caliphate of Córdoba; surviving in Spain after the Reconquista as the southwestern terminus of the Persian tradition.
From the Alhambra, through Italian Renaissance villa-garden adaptations, the Persian-Islamic geometry reached French formal gardening. Most European parterres are recognisable descendants of the chahār-bāgh.
Landscape architecture's modernist moment came later than architecture's, partly because the materials of landscape (plants, water, terrain) don't lend themselves to the abstract geometric reductions of 1920s modernist building.
Roberto Burle Marx (Brazil, 1909–1994). The first true modernist landscape architect. Burle Marx painted (his early training was in fine art); his gardens read like flat compositions in plan, with sweeping curves of differently-coloured tropical foliage forming abstract paintings on the ground. The terrace gardens at the Ministry of Education and Health (Rio, 1938, with Le Corbusier and Niemeyer); Copacabana Beach promenade (Rio, 1970), the world's most-walked landscape architecture, with its black-and-white wave-pattern paving; thousands of private gardens and public commissions across Brazil.
Burle Marx was also a working botanist — his collection trips to the Brazilian interior identified ~50 plant species new to science (some named for him: Heliconia burle-marxii). His house and garden at Sítio Roberto Burle Marx (outside Rio) are open as a museum and contain ~3,500 species.
Lawrence Halprin (US, 1916–2009). The dominant American postwar landscape architect. Ghirardelli Square (San Francisco, 1962), Lovejoy Plaza (Portland, 1966), Levi's Plaza (San Francisco, 1982), the Franklin Delano Roosevelt Memorial (Washington, 1997). Halprin's plazas were dynamic — water, irregular geometry, multi-level circulation, choreographed for use by people. He wrote about choreography (his wife was a choreographer); his fountain plazas were intended for occupation.
Geoffrey Jellicoe (UK, 1900–1996). British modernist; co-founder of the Institute of Landscape Architects (1929). Sutton Place (1980), the Kennedy Memorial at Runnymede (1965), the Hemel Hempstead water gardens. Jellicoe's Landscape of Man (1975, with Susan Jellicoe) is a canonical world-historical survey.
Garrett Eckbo, Dan Kiley, James Rose (US, the "Harvard Bauhaus" of the 1930s). Three students at the Harvard Graduate School of Design who collectively introduced modernist principles to American landscape design. Eckbo's Landscape for Living (1950); Kiley's Air Garden at the US Air Force Academy (Colorado Springs, 1959), the Miller Garden (Columbus, Indiana, 1955) — geometric, formal, consciously modern.
The Olmsted firm and its successors built much of urban America's public landscape. The major American park projects, beyond Central Park:
Prospect Park (Brooklyn, Olmsted & Vaux, 1867–73). Olmsted preferred this to Central Park — fewer constraints, larger pastoral meadow (the 90-acre Long Meadow, the largest open lawn in any American park), more wooded ravines.
Boston's Emerald Necklace (Olmsted, 1878–96). A 7-mile chain of nine connected parks from the Boston Common to Franklin Park. The first American large-scale park system; the model that Buffalo, Louisville, and others followed.
Buffalo's park system (Olmsted, 1868–98). Three large parks (Delaware, Front, Cazenovia) plus a connecting parkway network. Olmsted called it his most successful work.
The Niagara Reservation (Olmsted & Vaux, 1885). The first state park in the United States — preserving the falls from rapacious commercial development. Ecological reasoning ahead of its time.
The National Park Service (founded 1916). The federal extension of the park idea to scenic landscapes — Yellowstone (1872, the first National Park anywhere), Yosemite (1890), Glacier (1910), Grand Canyon (1919). The NPS's design language under Stephen Mather (first director, 1916–29) and Horace Albright (second director) developed a "park rustic" idiom — log lodges, native-stone walls, designed views — that has become the canonical American national-park aesthetic.
The Robert Moses parkways (New York, 1924–60s). Moses, the most powerful American urban builder of the 20th century, designed an extensive network of parkways and beaches (Jones Beach, 1929; the Belt Parkway; the Northern State and Southern State Parkways). The work overlapped with Olmsted's pastoral tradition and with car-centric mid-century planning, often badly. Moses's legacy is contested — Robert Caro's The Power Broker (1974) is the standard prosecution.
The American park inheritance is one of the country's most-undervalued cultural achievements. Most American cities have a designed landscape system that no European city of comparable size can match.
The most-influential single landscape project of the early 21st century. The High Line is a 2.3-km elevated park on the disused West Side Line freight viaduct in Chelsea, Manhattan, opened in three phases (2009, 2011, 2014). Designed by James Corner Field Operations (the lead landscape architects), with Diller Scofidio + Renfro (architects) and Piet Oudolf (planting designer).
The principles:
Reclamation rather than erasure. The freight rails, the original concrete deck, the chain-link fences are preserved or referenced. The rails are visible in the planting; some sections of the original deck are kept as paving; the industrial character is foregrounded rather than removed.
Designed wildness. Piet Oudolf's planting — ~210 species of perennials, grasses, and small trees — is naturalistic, prairie-inspired, deliberately seasonal (some species peak in spring, others in autumn). The planting reads as wild but is tightly designed and intensively maintained.
Slow circulation. The path is narrow (3–4 metres in most places); access is from a few stairs and elevators; the elevation removes the High Line from the street grid. The result is a slower, quieter, more contemplative park experience than ground-level public space allows.
The viewing platforms. Diller Scofidio + Renfro's "10th Avenue Square" — wooden tiered seating overlooking 10th Avenue traffic — and the "Falcone Flyover" through the Chelsea Grasslands give the path a series of architectural events.
The economic effect: the High Line catalysed an estimated $2 billion in adjacent real-estate development. Buildings designed to face it (the Standard Hotel, the IAC Building, Jean Nouvel's 100 Eleventh Avenue, Zaha Hadid's 520 West 28th Street) reshape the neighbourhood.
The political question: the High Line is now the canonical example of "linear-park gentrification." It made the surrounding neighbourhood unaffordable to its previous working-class residents. Whether this makes the park a failure (gentrifying) or a success (the neighbourhood economic gains were real and partially distributed) is debated.
The model has been replicated worldwide — Seoul's Skygarden (2017), Atlanta's BeltLine (continuing), Chicago's 606 (2015), the Promenade Plantée in Paris (1993, the High Line's actual precedent), and dozens of smaller projects. The "High Line effect" is now a planning category.
James Corner (born 1961, British, trained at the University of Pennsylvania) and his firm Field Operations (founded 1998) have been the dominant North American landscape practice of the 21st century.
The signature projects:
Fresh Kills Park (Staten Island, NYC; design 2003, ongoing implementation through 2036). The 890-hectare conversion of the world's largest landfill into a park three times the size of Central Park. The phased reclamation will be one of the largest landscape projects ever undertaken; partial sections opened from 2008.
The High Line (Manhattan, 2009/2011/2014). Above.
South Park at the Battery (Manhattan, 2015). Reclamation of southern Manhattan harbour edge.
Domino Park (Brooklyn, 2018). Conversion of the Domino Sugar Factory waterfront — preserving fragments of the industrial machinery in the landscape design.
Tongva Park (Santa Monica, 2013). Civic park on a former parking lot.
Lincoln Road redesign (Miami Beach, 2010). Pedestrian retail street with water features and palm groves.
Corner's intellectual project is "landscape urbanism" — the argument (developed at Penn through the 1990s with Charles Waldheim and others) that landscape rather than architecture is the principal medium of contemporary city-making. The argument is partly a response to the 1990s observation that urban edges, post-industrial sites, and infrastructure landscapes were defining the contemporary city more than its buildings did.
The critique: landscape urbanism privileges process and ecology over architectural definition. Its detractors (Andres Duany and the New Urbanists) argue it tends toward formless park-fields without civic structure. The argument continues; the buildings continue to age into the landscapes.
The Dutch planting designer who, more than anyone else, has changed how landscape architects design with plants in the 21st century. Oudolf (born 1944) trained as a horticulturalist; with his wife Anja he ran a nursery in Hummelo, the Netherlands, from 1982. He emerged in the 1990s as a designer associated with the "New Perennial" movement.
The principles:
Plants for structure, not just bloom. A traditional perennial garden is designed for peak summer flowering. Oudolf designs for the entire seasonal cycle — spring foliage, summer bloom, autumn colour, and (especially) winter form. The dried seed heads and stem skeletons of late-autumn perennials are part of the design intent, not waste to be cut.
Massed, not spotted. Plants are deployed in large drifts of single species or close associations, often hundreds of individuals of one plant. The visual effect is meadow-like rather than herbaceous-border-like.
Native and adapted, not exotic. Oudolf's palette draws heavily from North American prairie species, central European meadow species, and Asian grasslands — plants that fit the new-meadow ecological model rather than the colonial exotic-collecting tradition.
Design through plan-drawing. Oudolf's drawings (large hand-drawn plans showing every plant clump as a coloured shape) are themselves art. They've been exhibited at the Garden Museum, the Vitra Design Museum, and elsewhere.
The signature projects: the High Line (with Field Operations); Lurie Garden (Millennium Park, Chicago, 2004); the Battery (with Field Operations); Hauser & Wirth Somerset (UK, 2014); Trentham Estate (UK, 2003 onward); his own home garden at Hummelo.
Oudolf is in some sense the heir to Gertrude Jekyll (1843–1932), the British painter-turned-garden-designer who collaborated with Edwin Lutyens on dozens of Edwardian gardens and whose Wood and Garden (1899) and Colour in the Flower Garden (1908) defined the herbaceous-border tradition. The 2014 documentary Five Seasons: The Gardens of Piet Oudolf traces the work and the lineage.
The 1969 publication of Ian McHarg's Design with Nature reframed landscape architecture as an ecological discipline. McHarg (Scottish-American, 1920–2001), founder of the Penn landscape architecture programme that James Corner now runs, argued that landscape design should begin from a thorough analysis of the natural systems of a site — geology, hydrology, soils, vegetation, wildlife — and that "design" should largely be the elaboration of what the systems support.
McHarg's analytical method (overlaying transparent maps of different physical attributes to identify development-suitable and development-restricted zones) was the precursor of contemporary GIS-based planning. The ecological-suitability analysis is now standard in landscape practice.
The post-McHarg developments:
Restoration ecology. Designed landscapes attempting to restore ecological function — wetlands, prairies, dune systems, urban streams. The 1980s–2000s saw extensive prairie reconstruction in the American Midwest (the Curtis Prairie at the University of Wisconsin Arboretum, started 1934, is the founding example).
Green infrastructure. Landscape designed to perform engineering functions — stormwater management, urban heat mitigation, flood control, carbon sequestration. The High Line's planting is partly green infrastructure (the soil mass acts as stormwater retention); Portland, Oregon's Tabor to the River programme (2008 onward) is one of the largest urban green-infrastructure projects.
Urban ecology. The recognition that cities are ecosystems with their own (often unique) species assemblages, climate, and energy flows. The discipline interfaces with urban-ecology research at universities (Steward Pickett's Baltimore Ecosystem Study, 1997 onward) and with applied projects.
The novel ecosystem concept. Recognition that many post-industrial sites contain ecosystems that have no historical precedent — combinations of species (often partly invasive) that nonetheless function as ecological communities. Designing with novel ecosystems rather than against them is a 2010s landscape-architecture methodology.
Landscape architecture in 2026 is more biology-literate than at any prior point. Most major landscape practices employ ecologists, hydrologists, and (increasingly) climate-change specialists alongside designers.
The most visible 21st-century landscape work has been on previously-degraded sites — landfills, former industrial properties, abandoned infrastructure. The major examples:
Duisburg-Nord Landscape Park (Germany, Peter Latz, opened 1994). A 200-hectare park on a defunct steelworks. The blast furnaces, gas tanks, and ore bunkers are preserved as climbable industrial monuments amid newly-planted forests and gardens. The most-influential reclamation project of the 1990s; the model for many subsequent industrial-heritage parks.
Gas Works Park (Seattle, Richard Haag, 1975). The first major industrial-heritage park in the United States; the gasification plant ruins preserved as sculpture in the park.
Fresh Kills Park (Field Operations, 2003 onward). The Staten Island landfill conversion; will reach completion ~2036.
The Olympic Park, London (LDA Design and Hargreaves Associates, 2012). The Stratford Olympic site (a former industrial brownfield with severe contamination) reconstructed as the Queen Elizabeth Olympic Park. Continuing post-Olympic transformation.
Houtan Park, Shanghai (Turenscape / Kongjian Yu, 2010). A constructed wetland on a former industrial waterfront; performs water-cleaning function alongside park use.
Cheonggyecheon (Seoul, 2005). A demolished elevated highway converted into a 11-km urban stream and linear park. The most ambitious urban-decongestion landscape project of the 21st century.
Madrid Río (West 8 with Burgos & Garrido, 2011). The M-30 motorway buried; a 6-km park created on top, linking the city to the Manzanares River.
The 2030s pipeline includes Detroit's continuing urban-prairie reclamation (formal landscape architecture meeting unintentional rewilding); New Orleans's post-Katrina coastal restoration; and dozens of post-industrial waterfront projects in Chinese cities.
Climate change has become, in the 2020s, the defining problem of the discipline. Three working areas:
Coastal adaptation. Sea-level rise (predicted 30–80 cm by 2100, more in some regions) and increased storm intensity require rethinking coastal landscapes. Projects: Manhattan's "BIG U" coastal protection (Bjarke Ingels Group; under continuing implementation as Lower Manhattan Coastal Resiliency); the Dutch "Room for the River" programme (2007–2019, 30 sites along Dutch waterways given more space to flood); Hunters Point South Park (Brooklyn, 2013, designed for periodic tidal flooding).
Urban heat. Cities are 5–10°C hotter than their rural surroundings (urban heat island effect). Designed shade trees, cool pavements, water features, and green roofs all mitigate. The 2020s have seen large-scale tree-planting commitments — Singapore's 1-million-trees programme, New York's MillionTreesNYC (completed 2015), Paris's "urban forest" plans.
Stormwater management. Increased precipitation intensity, combined with impervious urban surfaces, produces flooding that traditional hard-engineering drainage cannot handle. Green stormwater infrastructure — bioswales, rain gardens, permeable pavements, stormwater wetlands — distributes the load through the urban landscape. Portland, Philadelphia, and Copenhagen are the major North American and European leaders.
The discipline's distinctive contribution: landscape architecture is the design profession most accustomed to working with natural systems. Its tools (planting, terrain, water, soil) are exactly the tools climate adaptation requires. The 2020s have positioned landscape architecture more centrally in city-planning conversations than at any prior point.
Two complications: climate-resilient landscape often costs more (initial construction, ongoing maintenance) than conventional alternatives. And the species palette that worked in 1990s plantings may not work in 2050 climate — plant selection now has to anticipate climate change rather than the local-historical climate.
Some of the most affecting late-20th-century landscape architecture has been memorial work.
The Vietnam Veterans Memorial (Maya Lin, Washington, 1982). Lin was a Yale undergraduate; her design — a 75-metre black granite V cut into a sloped lawn, inscribed with the names of 58,318 American war dead — won the public competition. The memorial is intensely visited (4 million visitors per year, more than any other Washington monument); the design redefined what a memorial could be (austere, name-focused, terrain-integrated rather than figurative-statuary).
The 9/11 Memorial (Michael Arad with Peter Walker landscape, Manhattan, 2011). Two square fountains in the footprints of the lost towers, ringed by inscribed names of the victims. Continuous water flow into a darkened central void. One of the most-thoughtful memorial spaces of the 21st century.
The Memorial to the Murdered Jews of Europe (Peter Eisenman with Buro Happold, Berlin, 2005). A field of 2,711 concrete stelae of varying heights on undulating ground covering 19,000 m². The visitor's experience as one walks deeper — the stelae rising from knee-height to taller-than-human — produces a disorientation that is the design's intent.
The National Memorial for Peace and Justice (MASS Design Group, Montgomery, Alabama, 2018). Bryan Stevenson's Equal Justice Initiative memorial to the victims of lynching in the American South. Eight hundred suspended steel monuments, one for each county in which a lynching is documented.
The FDR Memorial (Lawrence Halprin, Washington, 1997). A 7.5-acre sequence of four "rooms" along the Tidal Basin, one per Roosevelt term. Halprin's design uses terrain and water to walk visitors through Roosevelt's chronology. More conventional than the Lin memorial but underrated.
The good memorial landscape combines emotional weight, accessibility, and durability. The bad memorial (Washington has many) is figurative-statuary at scale without spatial logic. The discipline of memorial design now strongly favours the Lin-Eisenman tradition over the Beaux-Arts predecessors.
Designed public space is the principal civic deliverable of landscape architecture. The questions that define a good one:
Who is it for? A children's playground, a senior gathering space, a tourist attraction, a quiet retreat — these have different formal and programmatic requirements. The bad public space tries to be everything; the good one knows its principal users.
How is it accessed? Adjacent transit, parking, walking distance, ADA requirements. A park that is hard to reach is principally for the people who live next to it.
What programme does it support? Active recreation (sports fields, playgrounds), passive recreation (lawns, paths), civic gathering (plaza, amphitheatre), ecological function (wetland, forest), commercial activity (food stalls, markets). Many parks fail by trying to do everything; many succeed by doing one thing well.
How is it maintained? The single most-predictive variable of long-term park success is maintenance budget. A simple park that is well-maintained will outperform an ambitious park that is not. American urban parks have generally suffered from chronic under-maintenance; the Conservancy model (private fundraising for public space) has partially compensated.
How does it age? The 30-year question. The original design intent rarely matches the 30-year condition; the planting matures, the paving wears, programmes change, the surrounding neighbourhood shifts. Designs that allow for evolution age better than rigid masterplans.
Jane Jacobs's The Death and Life of Great American Cities (1961) argued for the small-scale street-life programmes that landscape architects of her generation had ignored. William Whyte's The Social Life of Small Urban Spaces (1980, with film) used time-lapse observation to document what people actually do in plazas (sit on movable furniture, drink coffee, talk to strangers, watch women). Both books are still required reading in the field; their observations have aged well.
Beyond the big international names, a short tour of regional masters worth knowing:
Luis Barragán (Mexico, 1902–1988). 1980 Pritzker laureate; an architect-landscape designer whose private commissions (his own home, Casa Barragán, Mexico City, 1948; Cuadra San Cristóbal, 1968; Las Arboledas, 1961) defined a Mexican-modernist landscape vocabulary of bold colour walls, water surfaces, and dramatic plant placement.
Isamu Noguchi (US-Japanese, 1904–1988). Sculptor whose landscape projects (UNESCO Garden of Peace, Paris, 1958; Sunken Garden, Chase Manhattan Plaza, NYC, 1964; California Scenario, Costa Mesa, 1982) brought sculptural-precision thinking to landscape design. The Noguchi Museum (Long Island City, NYC) is the working archive.
Bernard Lassus (France, 1929–). The "ambiances" designer; the highway aires (rest stops) of the French A-system; conceptual landscape interventions. A French tradition of philosophical-landscape practice.
Peter Walker (US, 1932–). PWP Landscape Architecture; the 9/11 Memorial landscape (with Arad); the Nasher Sculpture Center (Dallas, 2003); Sony Center Berlin (2000); minimalist plazas of high formal discipline.
Martha Schwartz (US, 1950–). The Bagel Garden (her own front yard, 1979) and a long career of conceptually-driven, often controversial public landscapes. The Necco Wafer-paved roof garden (Cambridge, MA) and Jacob Javits Plaza redesign are signatures.
Topotek 1 / Martin Rein-Cano (Berlin). Superkilen (Copenhagen, 2012, with BIG and Superflex) — a multicoloured public space curating objects from the homelands of the surrounding immigrant community.
Catherine Mosbach (France). The Louvre-Lens Museum park (2012, with SANAA architects); a quiet, ecology-led practice.
Kongjian Yu / Turenscape (China). Houtan Park (Shanghai), Qunli Stormwater Park (Harbin), the "sponge city" framework. The leading Chinese landscape practice; deeply ecological.
Vladimir Djurovic (Lebanon). The Centennial Garden (Beirut). High-design Mediterranean landscape practice that survived Lebanon's political turbulence.
The path into the profession.
The standard credential. A Master of Landscape Architecture (MLA) — typically 3 years for students without a design background, 2 years for those with one. The accredited US programmes (~70 in 2026) are evaluated by the Landscape Architectural Accreditation Board.
The leading schools. Harvard GSD (the Olmsted-era founding programme), the University of Pennsylvania (the McHarg-Corner lineage), Berkeley, Cornell, the University of Virginia, Wageningen (Netherlands), the Architectural Association in London. Most major landscape architects can be traced to one of half a dozen institutions.
Licensure. Required in 49 US states (Illinois being the historical exception, partially closed in 2022); the LARE (Landscape Architect Registration Examination) is the national exam. International equivalents vary; the UK has the Landscape Institute, the Netherlands has separate registration.
The career. Entry-level wages are modest (~$55–65k US in 2026); senior partners at major firms earn architect-comparable salaries. The largest US firms (SWA Group, EDSA, Hargreaves Jones, Field Operations, OLIN, Sasaki) employ several hundred each. Most landscape architects work in offices of 10–50 people. The profession is more gender-balanced than architecture (~45% women in 2026 vs. ~30% in architecture) and roughly comparable in racial diversity.
The non-academic path. Many distinguished landscape designers are not formally credentialled — Piet Oudolf (horticulturalist), Beatrix Farrand (self-taught), Burle Marx (painter). The discipline has a stronger tradition of plant-knowledge-based and self-taught entry than architecture does.
The autodidact's reading. McHarg's Design with Nature, Olmsted's Landscape into Cityscape, Jellicoe's Landscape of Man, Corner's Recovering Landscape, Treib's Modern Landscape Architecture, Oudolf and Kingsbury's Planting. A serious month-long bibliography produces a literate amateur.

What landscape architects actually do at their desks.
Site analysis. Soil borings, drainage analysis, tree inventories, microclimate observation, sun and wind studies. Most projects begin with a site visit and a working set of base drawings (topographic survey, existing utilities, existing vegetation).
Concept design. Sketches, model studies, plan diagrams. The landscape architect's principal output at this phase is the spatial logic of the proposal — circulation, programmatic zones, terrain manipulation, character of the planted edges.
Schematic design. Plans, sections, perspectives, materials studies. The proposal becomes legible to clients, contractors, regulators.
Design development. Detail design — the specific paving patterns, the exact wall sections, the planting lists, the irrigation schemes, the lighting plans.
Construction documents. Technical drawings sufficient for contractors to bid and build. Landscape construction documents typically include grading plans, drainage plans, planting plans, irrigation plans, lighting plans, hardscape construction details, and project specifications.
Construction administration. The landscape architect attends construction meetings, reviews submittals (paving samples, plant samples, lighting fixtures), supervises critical operations (tree planting, grading verification), and resolves field conditions that drawings didn't anticipate.
Software. AutoCAD or Vectorworks for drafting; Rhino and Grasshopper for complex form-finding; ArcGIS for site analysis; Lumion or Enscape for visualisation; SketchUp for early massing. The tools are increasingly architecture-overlapping; some firms now work primarily in BIM (Revit, ArchiCAD).
Plant knowledge. Less universal than it was 50 years ago. The old generation knew Latin names of hundreds of species and their cultural requirements; the new generation often relies on planting consultants (Oudolf is the most-used; many regional specialists). Still essential at the senior level; specialised at the junior level.
The recurring failure modes:
Maintenance abandonment. The single most common failure. A park or garden is built, the budget is consumed, ongoing maintenance is underfunded, and the landscape deteriorates. Most landscape architecture is more sensitive to maintenance than buildings; without consistent care the design intent dissipates within five years.
Wrong-climate planting. Designs that specify plants unsuited to the actual site conditions. Common in commercial work where the landscape architect is hired late and given a constrained budget; the plants die within two seasons and are replaced by whatever is on sale at the local nursery.
Over-design. Heroic geometric plans that don't accommodate actual use. People don't walk in straight diagonal lines; people don't use raised seating walls as benches; people don't sit in plazas with no shade. The Whyte / Jacobs critique of mid-century plaza design (largely empty plazas at the foot of office towers) remains relevant. Good landscape architecture observes how people actually behave.
Trees in wrong places. Trees planted under power lines, over septic fields, against foundations, in soil volumes too small to support mature growth. Tree-pit failure is the canonical urban-planting failure; mature street trees require ~30 m³ of unconstrained soil and rarely get it.
Drainage problems. Water moves; unaddressed drainage destroys pavements, kills plants, undermines walls. Most landscape architects' construction-administration time is spent on drainage corrections.
Privatisation drift. Public spaces incrementally converted to private control — through gates, hours-of-operation restrictions, programme exclusivity, pay-walling. Many famous "public" spaces in 2026 are partially or fully private. The Hudson Yards plaza in Manhattan is a notable example.
Irrigation dependence. Designs that look great on opening day but require ongoing irrigation that climate, drought regulation, or water cost makes unsustainable. The 2010s southwestern US drought removed thousands of acres of mid-century lawn-based landscape design.
Four directions.
Climate-resilient species palettes. The plant lists used in 1990 don't suit the climate of 2050. Landscape architects are working on transition palettes — species adapted to predicted hotter, drier, more-variable conditions. The science is incomplete but the working necessity is clear.
Densification of green infrastructure. The 2030s and 2040s will see green infrastructure become a default rather than an extra. Stormwater management through green systems will be code-required in more jurisdictions. Green roofs and walls will move from premium to standard. The landscape architect's role in conventional development will expand.
Indigenous knowledge integration. The 2010s and 2020s have seen growing recognition that indigenous land-management traditions (controlled burning, polyculture planting, water management practices) often outperform colonial-modernist landscape methods at ecological resilience. A generation of landscape practices (the Olin firm with various Native American consultations; the Australian Aboriginal-knowledge integration in fire-management; New Zealand's Māori-led conservation work) is operationalising this.
Anti-gentrification practice. The High Line's lesson — that well-designed public space can drive displacement — has produced a new generation of landscape architects focused on community-led design, anti-displacement covenants, and equitable park access. The Trust for Public Land's "ParkServe" mapping (showing American park-access disparities) and the Just Green Enough framework are working examples.
Landscape architecture in 2026 is more central to civic life than at any prior point. The 2010s urban-park renaissance is continuing; the climate crisis demands what landscape architecture is best at; the post-industrial-site reclamation pipeline is decades long. The discipline is healthy, growing, and having a productive moment.
Three claims.
The civic claim. The designed public landscape is the principal civic good a city produces beyond housing and circulation. Central Park, the Boston Emerald Necklace, San Francisco's Golden Gate Park, London's Royal Parks — these are inheritance from earlier civic moments, available to anyone, and largely free. Few investments compound civic value as reliably.
The ecological claim. The landscape architect's tools — terrain, vegetation, water — are the tools climate adaptation requires. The discipline is positioned to do consequential ecological work in ways that architecture, despite its "green" rhetoric, is not. Most major climate-adaptation projects of the 2030s will be landscape projects.
The aesthetic claim. The best landscapes are among the great human creations. Versailles, Stourhead, Katsura, Saihō-ji, Central Park, the Alhambra, Burle Marx's Sítio. These compare with the great cathedrals, the great paintings, the great cities. They are slower, more demanding of patience, more dependent on collaboration with nature than other arts. They are also more durable: a 17th-century building has aged badly; a 17th-century garden, well-tended, may be at the height of its powers.
The discipline's challenge is its temporal scale. Most landscape architects must convince clients, regulators, and the public to invest in something that won't reach its full character until the original investors are dead. The discipline succeeds when civic patience is available; it fails when it isn't.
