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.


Operated in partnership with the Santa Clara County Parks & Recreation Department.
