Why Grow River Oats?
This native grass is beloved for its distinctive, papery seed heads that emerge green and mature to bronze — perfect for dried arrangements and fall interest. The foliage turns golden in autumn, offering multi-season appeal. River Oats also stabilizes soil, making it a top choice for erosion-prone areas like stream banks and slopes.

It’s a host plant for several butterfly species and provides food and shelter for birds and small critters. Best of all? It spreads politely, forming clumps and naturalizing gracefully without taking over.
