Ever since Governor Jerry Brown announced his plans to mandate water restrictions in California, our phone has been ringing off the hook with people wanting to replace their lawns with drought-tolerant plants and natives. It’s comforting to know that people are taking the water issue seriously and doing their part to conserve. With everyone doing at least a little bit, we will be able to get through this drought and be able to continue to take showers and wash our dishes. We know that watching your green lawn turn brown is a sad thing and is a sacrifice that should be commended, but just because you don’t have a lawn anymore doesn’t mean that you need to have just a brown plot of land in your front or back yard. This can be an opportunity to beautify and get some gorgeous flowering California natives or other drought-tolerant plants in. Here is a list of some colorful flowering shrubs that, once established, take little to no water.
A large shrub about 8 feet tall and wide that spreads by underground rhizomes. The large paper-mache like flowers can get up to 5 inches in diameter with a large yellow center. Romneya likes well drained soil and full sun. It can be difficult to get this plant to establish after transplanting, due to the sensitivity of its roots, but once established can be a very vigorous grower. As with any plant establishing its roots in new soil, water well after transplanting. Then water about once a week during it’s first summer. By the following Spring no water will be necessary.
This cottage or wildflower garden plant has showy blooms that attract hummingbirds. Penstemon is about as low-maintenance as it gets. This plant loves dry conditions and will actually flower less if fertilized. Keep your Penstemon in full to part sun in well drained soil and she will thank you with gorgeous bright flowers throughout the Spring and Summer. There are many different varieties and colors to choose from.
