Rosa californica

Rosa californica, the California wildrose, or California rose, is a species of rose native to the U.S. states of California and Oregon and the northern part of Baja California, Mexico. The plant is native to chaparral and woodlands and the Sierra Nevada foothills, and can survive drought, though it grows most abundantly in moist soils near water sources. This thorny, flowering, fruit-bearing shrub is also deciduous, and grows vertically up to six feet tall. The meaning of its name is twofold; Rosa, that it resembles or is composed of roses, and californica, that it originates from California....read more on Wikipedia.
