Stephanomeria diegensis
Also called Wreathplant
San Diego wirelettuce is a wild annual herb of coastal hills and open ground in southern California and Baja California, grown mainly in the wild rather than in gardens. It is a tall, twiggy plant that can exceed two metres and drops its leaves early, so it is best grown from seed in full sun with well-drained soil.
Stephanomeria diegensis is a species of flowering plant in the family Asteraceae known by the common name San Diego wirelettuce. It is native to the coastal hills and ranges of southern California and Baja California, where it grows in many types of open habitat. It evolved as a hybrid of Stephanomeria exigua and S. virgata. Furthermore, it is thought to be the result of homoploid hybrid speciation, which is uncommon. The plant is frequently misidentified as one of its parents, especially if older taxonomic keys are used. This is an erect annual herb easily exceeding two meters in height. Its slender stem has many spreading branches. The basal leaves are linear to lance-shaped and up to 10 centimeters long. The leaves wither early and are absent for most of the year, giving the plant a twiglike appearance. Leaves on the upper stem are small and reduced.
