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.

Mornings at Martial Cottle Park is a program offering field trips for kindergarten–4th graders to learn about gardens from UC Master Gardeners.

Demonstration gardens map and plant lists

We have several demonstration gardens with different themes. Use the links below to see a list of the plants in each of the gardens. 

Please understand that while we attempt to update the plant lists on a regular basis, gardens do change. Plants may be added, moved, replaced, or simply die. Also, some of the plant lists are still in progress, and may have little to no information yet.

Important: While many of these plants are edible, do not eat any of them until you have done research or taken a workshop to be sure you know which parts are best to eat. Not all related species are edible. Be careful and don't make assumptions.

Please respect our gardens and do not pick any parts of the plants.

Our history

Raised bed planters
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 Fairs. Other plants are used for research and teaching purposes.
