About Tolmie's Star Tulip (Calochortus tolmiei) Calochortus tolmiei is a species of flowering plant in the lily family known by the common names Tolmie star-tulip and pussy ears. It is native to the west coast of the United States from Washington to California, where it is a common member of the flora in several types of habitat. It is a perennial herb producing a slender stem, branched or unbranched, to 40 centimeters in maximum height. There is a basal leaf up to 40 centimeters long which does not wither at flowering, and generally a smaller leaf farther up the stem. The flower cluster is a solitary bloom or a cluster of bell-shaped flowers. Each has white to pale pink or purple petals, each up to 2.5 centimeters long, and three narrower sepals beneath. The petals are usually very hairy on their inner surfaces, and may be fringed with long hairs as well. The fruit is a winged capsule 2 or 3 centimeters long containing several dark brown seeds.
