About the Mercer Society

The Mercer Society (TMS) is a collaboration of committed individuals dedicated to continuing Thelma and Charles Mercer’s legacy by providing support to the Mercer Botanic Gardens- Houston’s premier botanic garden.

Our goal is to engage, inspire and enlighten those of all ages through garden and plant-related educational, networking, volunteerism, social and fund-raising activities and events. A 501(c)(3) non-profit organization, we strive to enhance and beautify the Gardens for our visitor’s enjoyment by donating proceeds from our efforts to the botanic gardens.

The Mercer Society is known for its signature plant sale events: March Mart (March), Summer Color Conference and Plant Sale (June) and Autumn Plant Sale & Market (October). Plants are also sold nearly all year long at the Gift Shoppe. We pride ourselves on offering the area’s most unique and eclectic selection of trees, shrubs, tropicals, annuals, perennials, herbs, fruits and vegetables.

Mercer Grown: Our on-site Grower and her team of volunteers tend to our private nursery stock to bring you the very best in both distinctive and popular species.

All are welcome at The Mercer Society and the Gardens! Explore the other pages on our website! Follow us on Facebook too.

All proceeds from The Mercer Society events and fund-raising activities go to enhance the Mercer Botanic Gardens.
