Small, clumping, semiievergreen grass with showy flowers. Soft green leaves form dense clumps. Flowers are small and heart shaped and will quiver in the breeze.

This is a clumping cool season grass.

Prefers rich, moist soil in full sun. Tolerates light shade but will not bloom well. In hot climates needs to be watered or it will go dormant. Cut back in spring before new growth starts.
