Tufted hair grass

Deschampsia cespitosa

Preview: plant data is awaiting horticulturist review. A professional horticulturist hasn't reviewed our plant table yet. Lists still follow fixed rules for zone, sun, pets, deer and invasive status.

Deschampsia cespitosa is a semi-evergreen ornamental grass for gardens in zones 4–9. It grows 2–3 ft tall and 1.5–2 ft wide, so plant it 1.5 ft apart. Give it full sun to part shade and average water, and it copes with wet soil. It flowers yellow in June to August. In a FloraVista list it usually plays the grass role: a grass or grass-like plant that adds movement and fine texture in the middle. It is native to the Pacific Northwest, California, the Mountain West and the Northeast. Deer usually leave it alone, and it is not listed as toxic to dogs or cats. Our rules leave it out of lists in the Southeast, Florida and the Gulf, Texas and the South-Central states and the Desert Southwest, where summer heat, humidity or mild winters hold it back even inside its zone range.
