A Gardener’s Guide to New York’s High Line: Design, Plants, and Inspiration
Discover the naturalistic design, plant communities, and gardening lessons from NYC’s iconic elevated park, the High Line.
A Gardener’s Guide to New York’s High Line
The High Line is a celebrated public park in Manhattan, uniquely built on a historic elevated railway track. Stretching for over 1.5 miles above the bustling streets of New York City, it draws millions of visitors every year who come to experience its immersive gardens, art installations, and panoramic city views. More than a landscape, the High Line represents a revolution in urban gardening—fusing ecological restoration with cutting-edge design and horticultural artistry.
History and Vision
Originally designed by a collaboration between landscape architecture firm Field Operations, architects Diller Scofidio + Renfro, and Dutch planting designer Piet Oudolf, the High Line opened in 2009 as a new type of public green space. Their vision was to honor the wild plants that naturally colonized the abandoned tracks while crafting a park that would serve both people and urban biodiversity. Drawing inspiration from the 3-mile Promenade Plantée in Paris, the creators reimagined infrastructure as living, layered gardens.
- The High Line spans over 1.5 miles atop historic railway viaducts.
- Landscape design by Piet Oudolf emphasizes naturalistic planting, seasonality, and ecological resilience.
- Today, the park features more than a dozen distinct garden zones, each reflecting unique microclimates and habitats shaped by city surroundings.
Garden Zones: A Walk Through Diversity
As you walk from south to north along the High Line, you encounter a series of garden zones. Each is curated to respond to various exposures, wind, water, and soil conditions, creating environments that range from prairie-inspired communities to woodland groves and wetland pockets.
Below is a summary of key garden environments found along the route:
| Zone | Distinct Features | Signature Plants |
|---|---|---|
| Southern Woodland | Shaded by birch and serviceberry; cool understory planting. | Bowman’s Root, fescues, carex, Little Blue Stem |
| Prairie Meadow | Prairie-like plantings with native grasses and wildflowers. | Wildflowers, perennials, native grasses |
| Wetland Gardens | Feature a water element and plants adapted to moist conditions. | Graceful Cattail (Typha laxmannii) |
| Matrix Planting Zone | Piet Oudolf’s signature naturalistic drifts and blends of shape and texture. | Astilbe, geum triflorum, aruncus (‘Horatio’), cotinus (‘Pink Champagne’), knautia, alliums |
| Lawn and Urban Edges | Tall fescue and perennial rye alongside relic tracks. | Dogwoods, soft grasses |
| Woodland Spur | Native Northeastern woodland plantings, shaded by urban canopy. | Dogwoods, magnolias, sassafras, eastern cottonwood |
Microclimate Adaptation
The gardens are meticulously adapted to the varying microclimates along the High Line—sun, shade, shelter, exposure. That means carefully selected plant palettes for windy spots, deep shade cast by buildings, and areas with shallow, rocky soils above the old track-bed. Each environment is a model for balancing aesthetic beauty with ecological suitability, helping plants thrive without excessive inputs.
- Grasses and perennials dominate sun-exposed areas; woodland species fill shaded sections.
- In wet locations and areas with poor drainage, species such as Graceful Cattail are chosen for adaptability.
- Magnolia groves and climbers drape over railings, creating connections to street-level urban life.

Signature Naturalistic Planting
The High Line’s planting style, led by Piet Oudolf and the horticulture team, is known as matrix planting or naturalistic gardening. This approach arranges plants in large drifts and intermingled masses, focusing on contrasts in shape, texture, and form rather than a strict color scheme. The gardens change dramatically with the seasons, offering waves of seed heads, berries, foliage, and blooms that echo the industrial landscape beyond.
- Vertical accents: Astilbe “rockets” rise above wispy carex grasses.
- Round forms: Magenta allium heads and knautia float above the matrix.
- Dramatic contrasts: Smoketree bush creates pink puffy clouds, goat’s beard waves gracefully.
- Color harmony: Plant selections echo nearby building and railroad hues, enhancing unity.
Rather than relying on showy annual blooms, the High Line gardens celebrate plant life cycles—flowers, fading foliage, architectural seed heads, and winter silhouettes. This diversity supports pollinators and invites wildlife into the heart of the city.
Native Plant Emphasis
Native plants form the backbone of the High Line’s gardens. Many sections feature over 75% local species, supporting regional biodiversity and ecological stability. Examples include:
- Bowman’s Root (Porteranthus trifoliatus)
- Little Bluestem (Schizachyrium scoparium)
- Fescues and Carex sedges
- Gray birch, serviceberry, magnolia, dogwoods
- Butterfly milkweed, crabapples, eastern cottonwood
The diversity of native flora not only offers habitat and food for local birds, butterflies, and pollinators but also lends a sense of place—evoking the wild railway banks that preceded the park.
Pathways, Experience, and Flow
Movement is an integral part of the High Line’s garden design. Pathways avoid the “bowling alley” effect common in long gardens by shifting between straight passages and gentle curves, interwoven with garden beds. This layout encourages leisurely exploration, allowing visitors to meander through distinct habitats, cool off in shady groves, and admire panoramic views of Manhattan.
- Paths are a mix of linear and asymmetrical routes, broken by plantings and sculptural elements.
- Cascading climbers such as hydrangea and clematis spill over railings, softening boundaries and inviting street-level connection.
- Plank-like walkways reference the garden’s industrial heritage.
Garden Maintenance and Community Involvement
The gardens are expertly maintained by a dedicated horticulture team—led by senior director Richard Hayden—with support from volunteers. Special attention is paid to seasonal care, irrigation, and ecological stewardship.
- Over 10 staff horticulturists manage the gardens, adapting maintenance to plant cycles and urban challenges.
- Volunteer programs are essential, with teams helping to weed, prune, and care for hundreds of plant species.
- Innovative irrigation systems combine automatic and manual watering, responding to seasonal and microclimate needs.
After shifts, volunteers are treated to special garden tours—a nod to the shared stewardship and appreciation of the High Line’s living landscape.
10 Gardening Lessons from the High Line
- Embrace naturalistic planting: Mix drifts and textures, rather than formal rows or blocks.
- Choose regionally adapted native plants: Support local ecology while reducing maintenance.
- Design for microclimates: Notice sun, shade, wind, and soil depth—even in small gardens.
- Layer for drainage: Use gravel, filter fabrics, and subsoil layers under planting beds to manage moisture.
- Celebrate plant structure: Value seed heads, foliage, and winter forms as much as blooms.
- Create movement and flow: Avoid monotony by varying paths and breaking up long, narrow spaces.
- Use color echoes: Reference built surroundings for harmonious design.
- Plan for all seasons: Plant selections should provide interest from early spring through winter’s stark beauty.
- Encourage wildlife: Select plants for pollinators, birds, and beneficial insects.
- Engage the community: Involve volunteers, neighbors, and visitors in stewardship and learning.
