It is endemic to California, where it grows in wet granite rock habitat covered in thin soil layers, such as vernal pools and seeps.[2] It is known from the Sierra Nevada, Central Valley, southern Cascade Range, and locations in the eastern Transverse Ranges and the Peninsular Ranges in Southern California.[3]
