Frequently asked questions:

Why is native landscaping so important in California?

  • Native landscaping uses 50%-100% less water than conventional landscaping. At least 60% of our potable water ends up on the ground for landscaping, and natives are an ideal way to meet (and exceed) Gov. Brown's mandatory 25% water use cuts.
  • Native landscapes need little to no pesticides. The average gardener uses 20 times more pesticides than the average farmer. Excessive and incorrect pesticide use can be harmful to our health, the health of our children and pets, and the environment.
  • Native landscapes promote soil health and permeability. In contrast to landscapes that are dependent on imported water and chemical fertilizers, properly planned and well managed native landscapes promote chemical free landscapes. They support healthy soils and reduce pollution in urban runoff. Pollution from urban runoff is California's number one source of river and ocean pollution.
  • Native plants promote the health of beneficial animals better than non-natives. The future of our edible gardens depends on healthy pollinators. Native pollinators are the most effective, and they thrive best in native environments.
  • California native landscapes celebrate California's uniqueness. We owe our enviable "California lifestyle" to our wonderful climate. Also thanks to our climate, we have a wonderfully diverse palette of native plants. It's time to express our pride in their beauty and benefits to the world by embracing them in our landscapes.
