10 Essential Native Grasses and Sedges for Mid-Atlantic Gardens (10 photos)

Inland Sea Oats
(Chasmanthium latifolium)
Native from Pennsylvania to Kansas and south to Texas and northern Florida, with isolated populations in Arizona and Wisconsin

Inland sea oats, or river oats, is named for the oat-like flowers that it bears from late summer through fall, and because it is often found growing near water. While its native habitats are moist stream banks or woodlands, it can handle a range of conditions, from wet to moderately dry soils and partial to full sunshine. It has particular merit in the garden, as it can do well in moderately dry, shady locations.

It typically grows 2 to 5 feet tall in upright clumps. The broad leaves that hang from stiff stems give the impression of a small clump of bamboo. As with other warm-season grasses, its flowers begin to form in July. These mature to look like dangling clusters of oats. In the fall these flowers, as well as the entire plant, turn golden brown and are often retained on the stem well into winter. They show very well when illuminated by the low winter sun.

River oats is a fairly aggressive species, spreading outward by thick rhizomes and reseeding readily. It forms a dense network of roots that does a very good job of holding soil against erosion. But the roots also make it difficult to dig up and divide oversized clumps. Once split up, they do transplant successfully.
