Plant of the Week: Prairie dropseed

During September, Friends of the High Line is celebrating the Chelsea Grasslands – a special area of the park between West 18th and West 20th Streets that was inspired by the tallgrass prairie of the American Midwest. As part of the celebration, we're featuring plants and trees from the Grasslands throughout the month.

Sporobolis heterolepis or prairie dropseed, is a fine textured, clump forming perennial grass grown for its foliage and flowers. It's native to the tallgrass and mixed grass prairies of central North America from Texas to southern Canada. In addition, it's found further east, all the way to the Atlantic coast, though less common beyond the Great Plains.

Deep rooted and drought tolerant, it's one of the most elegant and refined of ornamental grasses. Sprobolus heterolepis produces delicate open panicles on slender stalks up to three feet high in mid-to late-summer. The foliage turns from a rich green hue to rusty orange in late autumn. It's resilient enough to resist flattening in the snow and provides year-round interest.

The inflorescence is strongly scented, which is unusual for a grass. This unique scent is unmistakable this time of year on the High Line. You will smell it right as you enter the Chelsea Grasslands, located between West 18th Street and West 20th Street. The scent is often compared to coriander or buttered popcorn. Rachel Hokanson, the gardener in the Chelsea Grasslands section of the High Line, thinks it smells like soap. It's known as a very popular grass for prairie restoration as well as mixed perennial borders and mass plantings. Prairie dropseed is also often found growing along roadsides and train tracks.

PLANTING TIP

Sporobolis heterolepis grows in dry to moist well-drained soil in full sun. This warm season grass typically flowers late summer and retains interest through winter. Prairie dropseed works well with perennials and spring bulbs that bloom in time to hide dying foliage. Once mature, they are long lived and trouble free for the most part. Propagate by seed or division.

WHERE TO FIND THIS PLANT

Prairie Dropseed can be found in the Washington Grasslands and Woodland Edge (between Little West 12th and West 13th Streets), Chelsea Grasslands (between 18th and 20th streets), The Wildflower Field and Radial Plantings (between 27th and 30th Streets), and Pershing Square Beams (at 30th Street).

The High Line's planting design is inspired by the self-seeded landscape that grew up between rail tracks after the trains stopped running in the 1980s. Today, the High Line includes more than 500 species of perennials, grasses, shrubs, and trees – each chosen for their hardiness, adaptability, diversity, and seasonal variation in color and texture. Some of the species that originally grew on the High Line's rail bed are reflected in the park landscape today. Every week we share one of our gardeners' current favorites with you.

Our horticultural team counts on members and friends like you to help keep the High Line beautiful and thriving. Join our community of supporters who play an essential role in the High Line's most important gardening projects.


Celebrating the Chelsea Grasslands is made possible, in part, by TD Bank—the Presenting Green Sponsor of the High Line.
