Semi-Annual Native Plant Sale
Our next Native Plant Sale will be held in the spring of 2023. Last fall, nearly 200 enthusiasts visited us that morning to take advantage of an excellent native-plant selection and support the Arboretum. Plants are generally priced from $5 to $20, and the proceeds benefit the Arboretum. We will post the date for the sale as soon as it’s decided.
Explore the Forest
This family- and dog-friendly trail is nearly one mile long. Descending and then rising gently, it’s an easy hike with numbered signposts along the way. An information-rich trail guide, keyed to those numeric posts, makes your hike even more interesting and educational.

The Arboretum’s gardens display a wide variety of flowers, shrubs and other plants. Largely native to the San Bernardino Mountains, many of them are identified by easy-to-read signs. The nearby Information Booth offers print and visual aids to help you learn even more!
