Grass, Sporobolos Heterolepsis (Prairie Drop Seed)

Prairie Dropseed

Sporobolus heterolepis, commonly known as Prairie Dropseed, is a warm-season native ornamental grass valued for its fine texture and graceful, fountain-like habit. Narrow, glossy green leaves emerge in spring, form a dense, arching mound through summer, and turn shades of golden-orange in fall, while airy, delicate flower panicles appear in late summer with a distinctive, sweet fragrance and persist into fall. Its refined form and native adaptability make it ideal for both naturalistic and formal plantings.
