Bloomeria crocea, also known as Goldenstar, is a geophyte of the Themidaceae from California and northern Baja California. It is found along hillsides, in grassland and chaparral edges, and in dry flats. Growing in full sun, itt prefers porous soil and semi-dry conditions. Its distribution ranges along the south coast from Santa Barbara County and western Kern County down to Baja California. It is also found on the California Channel Islands. The corm has a fibrous exterior and usually produces only one leaf. Plants produce six-petaled golden flowers that are clustered in a loose umbel. When the three-lobed stigma is fertilized, Bloomeria produces capsules that contain small black seeds. The seeds then require three to four years to become a mature plant.

Two varieties are currently recognised:
B. crocea var. aurea
B. crocea var. montana
