River Oats (Chasmanthium latifolium), named for its tendency to grow along waterways, is both ornamental and practical. With its slender stalks and oat-like spikelets that turn color during the fall, River Oats is often used in floral arrangements. In addition to attracting butterflies and being deer-resistant, this perennial grass provides grazing and produces seeds enjoyed by small mammals and birds.

River oats grows 3 to 6 feet tall with a blooming period (fruiting period, in this case) of mid to late summer (July-Sept).  It is especially useful in combating erosion due to its complex root structure. River oats is native to the Midwest of the United States and thrives in moist  soil, preferring partial shade to full shade conditions.
