Chasmanthium latifolium, known as Northern Wood-Oats, Inland Sea Oats, Northern Sea Oats, and River Oats is a grass native to the central and eastern United States, Manitoba, and northeastern Mexico; it grows as far north as Pennsylvania and Michigan. It is a native, cool-season perennial grass common in bottomlands, stream valleys, and other moist places. It grows from stout rhizomes and forms loose colonies. The open, nodding, flattened flower and seed clusters are distinctive.

It makes a lovely accent planting in the proper location, growing to 2.5' to 3' tall with graceful, flattened seed heads that flutter in the wind. They provide birds and mammals with food and serve as a host plant for some butterflies. River oats is a bright green during the spring and summer, becoming a coppery-yellow in the fall.

Prices listed are subject to change, based upon size change and availability.

We are a small local nursery with limited shipping capability. We will do our best to ship smaller material (usually 1 or 2 gallon), although we can sometimes ship larger plants with the pots removed.

We have some species that are not listed, as we have too few of them to make a full listing plausible. You can always inquire.

We will consider contract growing an order with appropriate advance notice and availability of seed, cuttings or lining out stock.
