Beach Evening Primrose Camissoniopsis cheiranthifolia (beach suncup or beach evening primrose) is a member of the evening primrose family that is native to dunes and sandy soils of coastal California and Oregon. These can easily be found along the inland side of the beaches in Santa Monica Mountain National Recreation Area between Sycamore and La Jolla Canyons. If you look through the archive you will find several other Evening Primrose flowers....

The Beach Evening Primrose grows prostrate (spreads out rather than up) along the beach surface, forming mats more than 36 inches in width. Long stems grow from the center. Silvery grey-green leaves with fine hairs that reflect the sun away are alternate, smooth-margined, the crown of the plant has oblanceolate leaves that are thick and form a rosette. Upper leaves are shorter and wider, ovate and clasp the stalk. By growing low to the ground with flexible swinging stems and having a deep taproot, this plant is able do well on the ever shifting sands of the dune environment.

The three quarters of an inch bright yellow, four-petalled flowers open in the morning (typical among suncups). Flowers fade to red /orange as the flower ages. A dense covering of pale hairs protects this plant from the hot summer sun. There are eight stamens and the stigma is classifed as capitate (ending in a distinct compact head). Terms describing this plant: Native, Yellow, Medium, Large, Clusters, Solitary, Simple, Herbaceous, Perennial, Early Spring, Late Spring.
