The Butterfly Mariposa is easily the most variable species of Calochortus in California. It can range in color from a delicate white, or pale yellow to a firey, or wine-like red--and the patterning of its petals can be even more variable. More than any other, this species lives up to its name in the way each petal can look like a butterfly wing.
