Low water plants
Water-Wise California Native Plants
California is a diverse state rich in many different plants and habitats. Much of the state is dry--from the slopes of the Sierra Nevada Foothills down to the coastal bluffs and chaparral of the coast. The plants that thrive here are beautiful and tough. By utilizing natives, specifically drought-tolerant natives, we can conserve water, energy, and create beautiful and sustainable landscapes.
