It is a slowly-spreading, clump-forming, cool season ornamental grass with an erect, slightly arching, slender clump of narrow, stiff, rich green leaves. In summer, tightly-vertical flower stalks rise well above the foliage to 1.5 mt tall bearing narrow plumes of feathery, purplish-green flowers which turn golden as the seeds mature in summer and eventually tan. This ornamental grass brings vertical accent to the landscape. Thrives in wet soils. Use as a specimen or group together. Easily grown in average, medium to wet soil in full sun. Does well in heavy clay soils, unlike many of the other ornamental grasses. Prefers moist, rich soils which do not dry out. Cut clumps to the ground in late winter just before the new shoots appear.
