Pink Muhly Grass is a clumping grass that grows to 3 feet tall and wide. The flowering clusters add about 1 foot, giving the plant a height of 4 feet when in bloom. The narrow leaf blades are a glossy dark green color, and grow to 1.5 inches long. Flower spikes are a deep pinkish-red color; with a loose, open appearance that give the tops of the plants a feathery look. These flowering stalks appear in fall and early winter, although bloom periods vary slightly with temperature.
