Adding native plants to your garden can...
- reduce yard work.
- lower water bills.
- mitigate fire risk.
- increase biodiversity.
- help endangered animals.
Some animals need specific native plants to survive. One well-known example is monach butterflies, who would die out without milkweed. Adding native plants to your garden, no matter how small, can make a difference to you and your community, and we’re here to help!
Explore and Restore
Improve your health at the Arboretum! Study after peer-reviewed study has shown that nature exposure is linked to:
- better sleep
- better cognitive function
- improved mood
- decreased stress
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!
