Northern Sea Oats

Chasmanthium latifolium

Plant Details:

Plant Type: Grass
Plant Family: Poaceae
Plant Description: Clump-forming perennial grass native to North America. Its chief characteristic are the flat seed heads that appear in late-summer to early-fall. The seed heads emerge green but turn to purplish-bronze with age eventually turning to tan when temperatures reach freezing. One of the most tolerant grasses to shade. Grows naturally along streams and other moist areas so it requires moist well-drained soils.
Plant Care: Cut back in late-fall once the plant is dormant or early-spring before new growth appears. Cut back to 3 to 12 inches depending on the total height of the grass.
