This blue-eyed grass species is a variable perennial, 3-18 in. tall, with umbels of starry, blue, violet or white flowers depending on the form. Individual flowers last only one day but are produced in great quantities. Foliage may be evergreen depending on moisture and temperature. Leaves are narrow and sword-shaped, occuring in fan-like sprays from creeping rhizomes which enlarge the colony each year.
Blue-eyed grass becomes very drought tolerant when established and may self-sow.
