Best grown in average, somewhat dry, well-drained soils. Plants grown in rich, moist, fertile soils usually need staking. Cut foliage to the ground in late winter before new shoots appear. Prefers full sun; is somewhat drought tolerant when established. Wet sites shorten its life considerably and lead to extensive winter injury. Spectacular fall color and considered deer resistant when established.
Truly one of the giants of the grass world. The tall flower stalks of Erianthus extend high above the foliage,and appear in late September to late October. 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.
No serious insect or disease problems.
