genus native to open dunes and sandy soils of coastalCalifornia andOregon . The genusCamissonia was distinguisned fromOenothera relatively recently, so this species was formerly known as "Oenothera californica".The Beach suncup grows prostrate along the beach surface, forming mats more than 1 m. across. It forms long stems growing from a central crown, lined with silvery grey-green leaves. The prostrate form and swinging stems allow the plant to survive well on the windy, shifting sands of the coast. The four-petalled flowers open in the morning (typical among suncups) and are bright yellow, fading to reddish.
