About California Sun Cup (Camissoniopsis bistorta) Camissonia bistorta is a species of flowering plant in the evening primrose family known by the common names southern suncup and California suncup. It 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. This is a hairy annual or perennial herb spreading from a basal rosette with stems reaching up to 80 centimeters long. Leaves are lance-shaped to narrowly arrowhead-shaped and sometimes toothed, and 1 to 12 centimeters in length. Toward the end of the spreading stems are nodding flower clusters of flowers, each flower with four bright yellow petals dotted with red at their bases. At the center are stamens and a protruding, nearly spherical stigma. The fruit is a straight or slightly coiled capsule up to 4 centimeters long.
