Interior Live Oak (Quercus wislizeni) is a slow-growing, evergreen tree with a distinctive broad crown. The glossy dark green leaves and reddish-brown bark give it a formal look.
In winter and spring, the oak blooms with green and white flowers. The tree's long, narrow acorns serve as a food source for deer.
Interior Live Oak is a resilient and adaptable species. It thrives at elevations ranging from sea level to 5,000 feet, making it an essential part of diverse ecosystems throughout California. Interior Live Oak grows in part to full shade and prefers dry, loamy soil.
