Bulbed woodland star is a California native perennial found in the Klamath Ranges, high Cascade Range, Sierra Nevada Mountains, Modoc Plateau, and northern eastern Sierra Nevada in dry, gravelly places at elevations up to 3,200 meters. Flowering from March to July, this plant produces delicate pink to white flowers 3 to 7 millimeters long with deeply lobed petals.

Its basal leaves are deeply three-lobed, with each lobe further divided and featuring sharp-tipped teeth, creating an intricate, delicate foliage structure. The plant produces spiny seeds and can have chromosome counts of 14 or 28.
