About GVST and our History

Gardening Volunteers of South Texas is a non-profit, 501(c)3 organization, founded in 2002. It is organized exclusively for educational, civic, scientific and charitable purposes. Our fundamental efforts are focused on water conservation, and environmental awareness while working collectively with fellow private, public and educational organizations to serve as an educational resource for the community.  




GVST started as a group of gardeners that were part of the BCMG program.  These members wished to take a different path and with the encouragement of several prominent garden mentors, began the organization in 2002. Today, it is great to have members that are not only current and past members of  the Master Gardener program, but members of other organizations such as San Antonio Garden Club, Native Plant Society, Rose Society, Herb Society and other groups that have as their focus water conservation and best practices gardening in the South Texas area.

GVST’s original “charter group” were also all members of Texas A & M’s Dr. Jerry Parsons’ Research and Development team that researched and propagated new-to-the-market plants at the old Peterson’s greenhouse on Seale Road. Dr. Calvin Finch, who was then the Conservation Director at SAWS, saw the potential in a new outreach group with a “Can do! When do we start?” attitude. With Calvin’s encouragement,  a non-profit 501c3 corporation, GVST, was formed.

Calvin suggested that “educator turned Hill County Gardener” Tom Harris, Diane Dondero and Anne Schiller get things organized.  When Diane passed away a few years ago, GVST planted a tree in her memory at Mitchell Lake Audubon Center. When Tom passed away in 2020, a GVST scholarship fund was established in his name. Anne is still very active in the gardening community.
