[Wikipedia] Range, Habitat, Flower Info: Calochortus westonii, common name Shirley Meadow 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).[3] It is vulnerable due to habitat loss from logging, development of ski resort, and fuel breaks.[4] Flowers bloom from May to June and petals are white or blue in color.[9] (link added by Mary Ann Machi)
