California Suncup, also known as Southern Suncap
Family: Onagraceae, Evening Primrose
The California suncup is an important food source for bees and other pollinators, who are attracted to the sweet nectar produced by its flowers. The plant is also used in traditional Native American medicine to treat a variety of ailments, including headaches, fever, and coughs.
The California Sun Cup is native to southern California and Baja California, where it grows in several types of plant community along the coast and in the coastal hills and mountain ranges.
It is commonly found growing in sandy flats, desert scrub, coastal scrub, chaparral, and grassland.
