Quercus agrifolia, commonly known as the California live oak, is a species of oak tree native to California and parts of Mexico. It typically grows to a height of 20 to 60 feet and features a broad, spreading canopy. The leaves are dark green, leathery, and have a distinctive spiny margin, which helps the tree conserve water in its native dry environments. This tree is an important part of the California ecosystem, providing habitat and food for various wildlife species. It is also valued for its durable wood, which is used in furniture and flooring. The California live oak is well-adapted to the Mediterranean climate, thriving in both coastal and inland areas.
