The California Wild Rose bears an abundance of pure-white to magenta-tinted flowers through Spring and Summer, giving way to dark-red rosehip fruits through the winter. The flowers attract hummingbirds, bats, and countless pollinators, while the root systems are some of the most effective, fast-growing systems for erosion control.
California Wild Rose (Rosa Californica)
•Flowers are great for pollinators, including native bees, butterflies, and beneficial insects—providing pollen and nectar over a long blooming period. 
•Rosehips (fruit) stay on the plant into fall/winter and feed birds, mammals, and small wildlife when other food is scarce. 
•Dense growth and thorny branches give excellent cover and nesting habitat for birds and small mammals. 
•Strong root and underground stem systems help control erosion along streambanks and moist soils.
