Description

River Oats is a native clump-forming upright grass with a distinctive seed head resembling oats. It is easily grown in moist to wet well-drained soils in part sun to part shade. It is fairly tolerant of shade and may spread aggressively by rhizomes and seeds.

The tall drooping seedheads emerge green in spring, turn tan in summer and then purplish in fall. They sway gracefully in the slightest breeze. The bamboo-like leaves often turn yellow-gold in fall if given enough sun. 

Use in naturalized areas, along streams or edges of water gardens.
