Noteworthy Characteristics

Erianthus alopecuroides, commonly called silver plume grass, is a Missouri native which occurs in dry, sandy to rocky, open woods and slopes in the far southern part of the State. Typically forms a dense clump of foliage to 5-6' (less frequently to 9') tall on reedy stems with flat leaf blades. Silvery flower plumes appear above the foliage in late summer and persist into winter.

Genus name comes from the Greek word erion meaning wool in allusion to the silvery woolly effect of the inflorescence.

Specific epithet means like the genus Alopecurus.


No serious insect or disease problems. Usually needs staking or other support.
