Prairie Dropseed
Sporobolus heterolepisAlso known as Northern Dropseed
Prairie dropseed forms dense, fountain-like mounds of emerald-green, thread-like leaves that cascade toward the ground before turning brilliant copper and gold in autumn. During late summer, airy flower panicles hover above the foliage, releasing a distinctive aroma often compared to buttered popcorn, coriander, or roasted nuts. These deep-rooted perennial tussocks are keystone anchors of remnant tallgrass prairies, storing vast reserves of carbon and providing crucial shelter for overwintering insects and ground-nesting birds.
