prairie dropseed

Sporobolus heterolepis (Prairie dropseed) is useful in the landscape for its fine-textured foliage that brings year-round interest.

Prairie dropseed is a bunch-type grass that grows up to 3 feet tall. Its leaves are narrow and arch outward, giving plants a tuft-like appearance. Leaves are green in spring and summer, changing to rusty-yellow in the fall. Native Americans ground the seeds of prairie dropseed to produce flour. In Lurie Garden, prairie dropseed is a favorite for birds to browse for seed. Some people say that prairie dropseed flowers produce a popcorn-like scent!

In Lurie Garden, S. heterolepis is used to weave together groups of other plants–acting as an ecologically important and aesthetically effective connector of horizontal and vertical spaces between planting groups. Summer brings foliage that is a rich green, fading to a golden rust color in the fall, and eventually to a light yellow-brown in the heart of winter. For the true four-season garden, S. heterolepis provides not only color and texture interest but also long-lived structural impact. The rounded-tufted to reflexed vase shape of S. heterolepis is maintained throughout the year, with foliage tough enough to sustain its shape even under heavy snowfall. Additionally, prairie dropseed imparts excellent ecological function to the garden–providing seed for birds and other animals to feed on throughout the winter, and furnishing an ample supply of nest-building material in the late winter and early spring.
