Who we are

We are a collaboration of individuals dedicated to engaging our visitors in learning about plants, preserving Thelma and Charles Mercer’s legacy by providing financial support to Mercer Botanic Gardens, inspiring future generations and continuing the rebuilding of Mercer Botanic Gardens following the devastation left by Hurricane Harvey. We are a non-profit 501(c)(3) organization partnering with Mercer Botanic Gardens.


We are pleased to announce that Mercer Botanic Gardens officially reopened on Saturday, March 17, 2018! We are delighted to be back and invite the community to return to our lovely gardens and see how we survived Harvey!

Key structural damages resulted following both the April 18, 2016 Tax-Day Flood and Hurricane Harvey. Access to Storey Lake, long a favorite destination for visitors, with its striking pavilion, fountain jets and delightful turtles that beg for treats, was barred and still remains so.
