About Southlake PGS
Southlake Perennial Garden Society is a non-profit organization in Southlake, Texas. We are dedicated to educating our members and the community on gardening topics specific to the North Texas area.
Our purpose is to promote, encourage and share practical and responsible gardening techniques with other gardeners encouraging the implementation of native and adapted plants and perennials in the suburban Texas landscape.
As a nonprofit focused on education, we use funds raised from our biennial Garden Tour to educate the community and sponsor the Butterfly Release at the Southlake Monarch Butterfly Festival.

Event - Annual Butterfly Release

September 17, 2022
Southlake PGS sponsors the annual Monarch Butterfly Release, a University of Kansas Science Research Program called "Monarch Watch". The City of Southlake purchases the butterflies and PGS maintains and coordinates the butterfly tagging event. The tags enable the University to learn about Monarch migration patterns. Along with the City of Southlake, PGS helped over 400 children plus their parents release the butterflies to the delight of everyone in 2021..
