What to see and do
The extraordinary presence of this garden within a 287-acre agricultural setting in a County and State Park provides a unique learning environment for the public. Community hands-on training to support and encourage healthy communities and ecosystems through sustainable landscape practices is the main focus. Water conservation, green waste reduction, and local sustainable gardening practices are just a few of the classes we deliver to youth and adults in a hands-on learning environment.

By the end of 2016, we completed construction of a 72-foot Solar Light Greenhouse. The greenhouse is used to grow most of the plants for Master Gardener projects throughout Santa Clara County. Many of the vegetables, flowers, herbs and plant seedlings grown on-site are sold at our Spring and Fall Garden Markets. Other plants are used for research and teaching purposes.
