Erigeron sanctarum is an uncommon species of flowering plant in the family Asteraceae known by the common names saints fleabane and saints daisy. It is endemic to California , where it is known from San Luis Obispo and Santa Barbara Counties including two of the Channel Islands (Santa Rosa and Santa Cruz, both in Santa Barbara County).[1][2]
Erigeron sanctarum grows in coastal and inland chaparral and oak woodland, and sandy coastal scrub habitat. It is a perennial herb producing an upright stem up to 40 centimeters (16 inches) long surrounded at the base by spoon-shaped or oblong leaves a few centimeters long. There are smaller, narrower leaves along the lower part of the stem. The inflorescence is 1-3 flower heads lined on the lower outside with hairy phyllaries. The head has 45–90 blue or purple ray florets surrounding many yellow disc florets. The fruit is an achene with a pappus of bristles.[3][4]
