Chasmanthium latifolium, referred to commonly as northern sea oats and less commonly as 'fish-on-a-fishing-pole,' is a native ornamental grass capable of growing two to five feet tall and 12-30 inches wide. Seed heads emerge green in mid-summer, but by August and September, persistent seed heads develop a purplish bronze hue, while its leaves turn a coppery color after frost, 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 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 may spread aggressively; spread can be controlled by cutting the grass back to the ground in late winter or early spring. As an added bonus, northern sea oats attracts birds with its seed, which may help to control its ability to self-seed.
