About Weed's Mariposa Lily (Calochortus weedii) Calochortus weedii is a species of flowering plant in the lily family known by the common name Weed's mariposa lily. It is native to the coast, foothills and mountains of southern California and Baja California, where it is a member of the chaparral flora. It is a perennial herb growing from a bulb, producing a slender, branching stem 30 to 90 centimeters tall. There is a basal leaf up to 40 centimeters long which withers by the time the plant blooms. The flower cluster bears 2 to 6 erect, widely bell-shaped to spreading flowers. Each flower has three narrow sepals and three wider and sometimes shorter petals, each segment up to 3 centimeters long. The petals are oval or wedge-shaped and may be any of a variety of colors, from cream to deep yellow to reddish purple. The petals often have reddish brown borders and flecks, and a coating of hairs on the inner surface. Don't expect it to flower every year. The bulb needs a few years to recover after flowering. The fruit is an angled capsule 4 to 5 centimeters long. There are two recognized varieties; var. intermedius is a rare plant with a more restricted range.
