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: Use hand pruners or hedger to cut and remove 2/3 of the total grass height. Trim edges. For warm season grasses (more common), this is best done in late winter to early spring. For cool season grasses apply the same maintenance practices in the late fall, once the plant is dormant.
