Botanical Name

Plant Common Name

Muhly Grass, White Muhly Grass

General Description

White muhly grass is a clumping, warm-season perennial native to the eastern United States, Mexico, and the West Indies. This fine-textured grass blooms in late summer with a cloud of ivory flowers on upright flower stems.

Muhly grass needs very little care, and tolerates a wide range of conditions, from wet to dry sites, acidic to alkaline soil, salt spray, and poor soil conditions. It is drought tolerant, but limiting water can also limit the mature vigor and size of the plant. The spectacular fall color makes 'White Cloud' a great accent in a mixed border, especially alongside pink-flowering muhly grass and tall asters. In winter, the dried stems cast a soft mystical silhouette in moonlight or at dawn or dusk. Cut off dried stems low to the ground in late winter.
