It is endemic to California, where grows in the granitic soils of several of the central and southern mountain ranges, usually between 6,000 and 10,000 feet above sea level. This is a short-stemmed onion, growing to heights of just a few centimeters from an oval-shaped bulb. It sprouts a single long, pointed onion leaf. The inflorescence contains up to 20 dark-veined purple flowers each up to a centimeter long with dark purple anthers.
