Deschampsia —commonly called hair grass–is an ornamental clumping grass with narrow, rough leaves that are often topped by airy clouds of yellowish flower panicles in late spring or early summer.

Deschampsia leaves are thread-like and linear. They are suited for mixed, herbaceous, shrub borders. They can be used in mass plantings. Deschampsia is best suited for cool-summer regions.

Descahmpsia is a genus of about 50 species of tufted or tussock-forming herbaceous or evergreen perennial grasses. Descahmpsia is native to damp meadows and woodland clearing in temperate zones and on high mountains in tropical regions.
