The California Wild Rose is a beautiful rose species that grows through the coast and foothills of California, and in the mountains up to elevations of 6000 feet. It is a deciduous thicket-forming shrub with prickly, curving stems. Each rose is open-faced and generally flat, with five petals in any shade of pink from almost white to deep magenta. The fragrant flowers may grow singly or in flower clusters of several blooms. It produces typical rose hips containing yellow seeds. The plant is native to arid regions and can survive drought, but it grows most abundantly in moist soils near water sources. It is most often used as a barrier planting in a garden where it can be allowed to form a large thicket. It can go summer dormant (or partially) if it doesn't get enough water. Berries may or may not happen, but California Wild Rose is still a good background foundation plant in leaf.
