Upcoming Events

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.

You can help!

We welcome community volunteers at the garden. If you enjoy working outside in a garden, or even indoors in a greenhouse, we'd love to have you join us. Our workdays are Wednesday and Saturdays from 9 am–noon. You can come for all or part of the time. Sign up for our mailing list, to get updates about workday information.

Note that all volunteers need to sign a UC ANR waiver form. Bring it with you or fill one out on your first volunteer day.

Our history

In the summer of 2015, Master Gardeners began working on a four-acre parcel covered in weeds. After a year of hard work, there was a thriving Native Garden, 51 raised beds for research and ornamental plants, a Farm Stand, a Barn with rain catchment, and pathways into the parcel.

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.
