Description

Calochortus striatus erects a stem usually only a few centimeters tall but sometimes quite a bit taller, and a long basal leaf which may lie flat on the ground.

At least halfway up the stem it may branch, and atop each branch is a bell-shaped lily bloom. Pointed sepals form the base of the flower and above are three rounded petals, which may be slightly toothed and 2−3 centimeters long. The petals are very light to very dark pink, lilac, or purplish with darker pink or purple veining or mottling. The cup of the flower is somewhat hairy. The anthers are bright to dull pink, with pink pollen. The bulb blooms from April to June.

The capsule fruit is up to 5 centimeters long, producing flat seeds.
