Calochortus westonii
Also called Weston's Mariposa, Shirley Meadows Star Tulip
Shirley Meadows star-tulip is a rare, bulb-forming wildflower found only in the Greenhorn Mountains of California, with white or blue flowers in May to June. It is a difficult species to cultivate and is best grown from ethically sourced bulbs or seed by experienced growers.
Calochortus westonii, common name Shirley Meadows star-tulip, is a rare endemic plant known only from the Greenhorn Mountains range of the southern Sierra Nevada, within Kern and Tulare Counties, California.
It grows in open locations in meadows and woodlands at elevations of 1,500–2,000 m (4,900–6,600 ft). It is vulnerable due to habitat loss from logging, development of ski resort, and fuel breaks.
