LA County Arboretum & Botanic Garden

The L.A. Arboretum has flourished for over 60 years as an educational resource focusing on unique plant collections, book collections, and historic preservation.

Our mission is to cultivate our natural, horticultural and historic resources for learning, enjoyment and inspiration. We strive to reflect Southern California’s distinct climate, community and openness to new ideas.  

The Los Angeles County Arboretum and Botanic Garden is a unique 127-acre botanical garden and historical site that includes Native American, Rancho Period, and late 19th century treasures. In addition to concerts and tours, we offer activities and events that cater to every audience.

This landscape is the setting of many rich cultural stories. Share yours with us!
