CALAMAGROSTIS

These Eurasian natives are sturdy, clumping grasses with feathery flower plumes that fade from purple-tinted green to yellow, then buff. These persist into winter and can be used for fresh or dried arrangements. Cut back clumps low to the ground in late winter, before new growth begins.

Calamagrostis x acutiflora
