The plant variously known as inland sea oats, inland wood oats, and Indian wood oats may have received those common names to help distinguish it from the ‘sea oats’ (Uniola paniculata) which grow in sandy coastal areas.
Inland sea oats (Chasmanthium latifolium) aren’t found anywhere near the ocean. A clump-forming, upright grass, the plant grows along the rocky slopes of streams and rivers, in woodland areas, and in flood plains. A shade and drought tolerant ornamental grass that also can thrive in full sunlight, it’s often used for erosion control, and is prized by wildlife both for cover and for food.
Easily recognized because of its flat, drooping seed heads and arching stems, the plant is native to the eastern United States from Pennsylvania to Florida, and thrives as far west as Wisconsin and Texas. While it can become a little tatty at the very end of its growing cycle, it soon re-emerges, ready to delight the eye.
