Salvia leucantha (Mexican Bush Sage) This drought tolerant Mexican native prefers sunny, well-drained sites and will survive with no supplemental irrigation is most parts of the state. In order to promote an abundance of late summer and fall flowering spikes, the plant should be sheared several times during the summer months. The subsequent regrowth produces a sturdier more compact plant as well.
Try Plants That Take the Heat For hot, sunny areas, you can't beat a festive combination of 'Victoria' blue salvia, 'First Kiss Orchid Halo' annual vinca, and white narrow-leaf zinnia. These tough-as-nails plants love the sun and require almost no maintenance. Once established, they're relatively drought tolerant.
