The California Wild Rose, Rosa californica , is a rather variable species that grows in the Western United States. My description is based on plants growing within 2 miles of my home in northern Monterey County, California, and may not apply to populations in other areas. R. californica is said to grow in USDA zones 5-10. It also grows in full sun where there is adequate water. We get little or no rain here from May-October, so R. californica , like all of our native plants, is quite drought tolerant.
Different individuals vary widely in height.
The tallest individuals grow 6 to 8 feet tall. The shortest individuals grow 2 to 3 feet tall. Taller individuals are more common. It seems to me that the shortest individuals tend to grow in the dryest areas. I plan to transplant some of them to irrigated places next Spring to see if they grow taller.
