About

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.

How to grow it

Rosa californica is used in California native gardens and habitat gardens, forming colonies, and attracting wildlife with the bright rose hips in autumn. Hard, dry internal seeds can be extracted by hand from mature, bright red hips. The wildrose can also be propagated with stem or rhizome cuttings.

Where it grows

Rosa californica is a common plant native to California. It is primarily found in elevations of below 6,000 feet. While most common in moist regions like river banks, the plant can also adapt to various soil textures, develop drought resistance, and has common-pest and disease resistance.

Uses

Rosa californica is readily acclimated. Its natural propagation helps restore damp areas. Subterranean stems stabilize the surrounding earth. Thorny thickets offer ground cover, shelter, and even nests for organisms.
