Chasmanthium latifolium (Sea Oats) Unity Grown

Chasmanthium latifolium, referred to commonly as sea oats or northern sea oats (and also less commonly as 'fish-on-a-fishing-pole'), is a native ornamental grass capable of growing 2-5' tall in dense clumps up to 2-3' wide. As an early-growing warm-season grass, small growth points appear from the root in the early spring, growing to full size over the course of the summer. Flattened, spiky seed heads emerge green in mid-summer, but by August and September, persistent seed heads develop a purplish bronze hue before maturing to coppery tan tones, matching the foliage after frost, and providing excellent fall color and multi-season interest.

Noted for its attractive drooping, scale-like flower/seed heads which resemble oats, northern sea oat grows best in full sun to partially shaded areas with higher moisture like woodland slopes, low-lying thickets, or on stream banks. Chasmanthium latifolium is known to self-seed easily and spread via rhizome, so it may spread aggressively when left unattended in small spaces. As an added bonus, however, northern sea oats attracts birds which eat the seed and may help to control rampant spreading over time. Perfect for filling in dense borders or for naturalizing in forest understory environments, Chasmanthium latifolium's hardy behavior and its showy, ornamental seed heads are an excellent addition to many garden types.
