There is a wisteria, Wisteria frutescens (American wisteria), native to North America that is very attractive and not nearly so invasive as the Asian wisteria, or Wisteria sinense, which is probably what you have. Unfortunately, that native wisteria grows no further west than Texas, and would not do well in California. In the western edge of Riverside County, near the border with Mexico, you are going to need plants that are semi-tropical in nature. You did not say if you wanted a shrub or a vine for your patio cover, so we will look for both in our Recommended Species for Southern California. Unfortunately, we did not find a single evergreen vine native to Southern California, so hopefully some of the flowering evergreen shrubs we found will suit your purposes. Follow the links on each plant to find out more about its habits, wildlife attractions and light requirements.
