Things to Know

Wheelchair accessibility is limited. There are steep hills and uneven, loose trails. Unfortunately, the width, grade, and surfacing of our pathways does not allow for safe transportation or shuttling for members of the public on golf carts. Please contact us if you have questions.

Please leave pets at home (except service dogs). Cracking your car windows does not keep your pet safe. When outside temperatures are only 70oF, it can reach 100oF in your car in just 20 minutes.. 

Photography is welcomed. 

Picnic areas are scattered throughout the garden and near the parking lot.

We encourage guests to bring water in refillable water bottles. Water is available in the Gift Shop for purchase, but there is no access to drinking water on the trails.

Restrooms are located near the parking area and in the Garden northwest of the arbor. Note: the Arbor restrooms are Port-a-Potties.

To ensure the tranquility of the garden for all, biking and smoking are prohibited

We share the Garden with rattlesnakes and mountain lions. For your safety, stay on the paths.

The Garden is a living museum with a scientifically documented collection. Many plants are rare or endangered and therefore significant to conservation efforts. Please do not remove seeds or cuttings from the garden.

Special Study: 
The garden is open year-round for horticultural students and professionals, for the purpose of botanical research and private horticultural study. Please contact us for more information.
