Deschampsia flexuosa (Wavy Hair Grass) is a fairly obscure native grass that I have enjoyed growing in my garden. It was slow to take, but as can be seen in the picture above it has begun to fill in nicely. It is notable in part because it is shade tolerant unlike most other grasses, and it forms short dense mats with pleasantly soft flower and seed heads. I saw a line drawing in William Robinson's The Wild Garden of peonies growing in a swath of grass. Maybe this Deschampsia can be that swath of grass for my peonies growing on the edge of the canopy of a silver maple.
