Native plants of California are species that have evolved in the region over thousands of years. They are adapted to the local climate, soil, and ecosystems, making them crucial for maintaining biodiversity. Examples include the California poppy, the state flower, and the coast live oak, which provides habitat for various wildlife. These plants play a vital role in supporting local ecosystems by providing food and shelter for native animals. They also help prevent soil erosion and conserve water. By using native plants in landscaping, residents can create sustainable gardens that require less maintenance and are more resilient to local environmental conditions.
