Fairly common in the southeast in low damp open woods, stream margins, and ditches, River Oats is an attractive, upright arching grass resembling somewhat the more familiar Sea Oats of southern sand dunes. In full sun, it grows 3 feet tall with leaves 1/2 inch in width. In some shade, expect taller plants that may need some staking. The flower/seed heads of River Oats which are effective from midsummer through mid-fall, are especially attractive. Long oblong, 3 by 1/2 inch wide spikelets with a distinct herringbone pattern are paper flat and pendant on thread-like pedicels dangling like earrings. These appear in arching sprays above the foliage and gracefully shimmer in the breeze. Summer color is medium green turning to yellow then brown in fall. Grow River Oats in sun to part shade, and dry to wet. It spreads moderately by rhizomes and also naturalizes by seed. We like it with Boltonia, Turtlehead, Orange Coneflower, and New England Aster.
