Also called Uniola latifolia or Northern Sea Oats, River Oats is an ornamental grass easily identifiable from its drooping inflorescences and compressed spikelets. It is commonly used as a low-maintenance shade of grass or prevents soil erosion. It readily self-seeds and can become a dense mat in a short amount of time. If River Oats become too aggressive, they are easily transplanted or removed. River Oats thrive in moist sand, loam, and clay.
The pale green spikelets turn golden-brown by fall, and the seed stalks are beautiful all year long and commonly used in native flower arrangements or dried arrangements. Birds and small mammals often consume the seeds for winter food, and River Oats are one of the host plants of the Pepper and Salt Skipper.
