Description

Indian woodoats is a clumping ornamental grass, forming mounds up to 4' tall. Its leaves are bamboo-like, green to blue green, arching, and turn shades of yellow and brown in fall. It is best known for its oat-like, flat seed heads that are pale green when they emerge, turning to tan, then brown as they mature.

Cultivation

Chasmanthium latifolium is one of the more shade tolerant ornamental grasses. It can be grown in full sun, so long as it is in a moist environment. It does best in rich, well drained soil, in part-sun, to part-shade. Indian woodoats will readily self seed, producing large colonies that can reduce erosion along stream banks. Plants should be cut back to their crown in late winter or early spring, before the new growth emerges. Blooms June through September. Zones 4-8

Propagation

Propagate by clump division in spring, or by seed in spring or fall.

Additional Notes

Though some common names refer to this grass as a type of "sea oat", this is somewhat of a misnomer: Chasmanthium latifolium is neither salt tolerant, nor is it salt-spray tolerant. The seed stalks are a favorite in dried flower arrangements.
