Hair Grass

Deschampsia

Deschampsia caespitosa ( Tufted Hair Grass )
A fast growing, finely textured grass, forming a semi-evergreen ( evergreen zones 7 to 9 ) foliage clump reaching a maximum size of 3.5 x 5 feet. It is native to North America ( from far northern Alaska to Nunuvat to Greenland; south to California to South Dakota to North Carolina ) as well as northern Eurasia. It is critically endangered in Indiana and Kentucky. Threatened in New Jersey. It was once widespread but localized throughout Pennsylvania though it now threatened in that state and completely absent from the middle. The Tufted Hair Grass is a cool season grass that grows mostly during spring and fall though remaining green during summer.
It is an excellent choice for mass plantings on wet sites.
The deep green leaves are very narrow, up to 0.2 inches wide.
The pale purplish-green flower panicles up to 10 inches in length, appear during mid-summer.
They are followed by loose, airy, hazy seed panicles, reaching up to 6 feet high.
This grass remains attractive during autumn and winter.
Hardy zones 4 to 9 ( likely 1 or 2 for seed source from the Northwest Terr. & northeast Alberta ) in sun or partial shade ( may need protection from hot afternoon sun ) on moist, well drained soil. Very soil tolerant including wet clays. Cut back ( to 1/3 height - more may damage the crown ) very early during spring before new growth begins. Dividing should also be done very early in spring.
