Beach Primrose
Onagraceae (Evening PrimroseFamily)


Beach evening primrose is a prostrate-stemmed perennial with dense gray-green pubescent herbage, and alternate, smooth-margined leaves, the lower oblanceolate, thick and in a rosette, and the upper shorter and wider, ovate and clasping.  The flowers are solitary and sessile in the leaf axils and are composed of four reflexed sepals and four bright yellow petals rarely with 1 or 2 red spots near the base.  The eight stamens are unequal, four short and four long, and they surround the headlike stigma.  The fruit is a somewhat coiled, densely hairy, quadrangular capsule not quite an inch long containing several ovoid brownish-black seeds in one row per chamber. Beach primrose is a common coastal strand plant, forming dense mats on beaches and in sand dunes along the entire coast of California and blooming from April to August. These pictures were taken at Torrey Pines State Park.
