Bamboo muhly
Muhlenbergia dumosa
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.
Hardy in zones 9–11, Bamboo muhly is an evergreen ornamental grass. It grows 3–6 ft tall and 3–5 ft wide, so plant it 3.5 ft apart. Give it full sun to part shade and little water once established. It is grown for its year-round foliage rather than its flowers. 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 Desert Southwest. 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 and the Pacific Northwest, where summer heat, humidity or mild winters hold it back even inside its zone range.
