June 2nd Chapter Meeting: Encouraging Native Landscapes in HOA Neighborhoods

Our Tuesday June 2nd chapter meeting will be available to attend in person at the Heard Museum in McKinney or online via Zoom. The program will feature Diane Wetherbee presenting on “Encouraging Native Landscapes in HOA Neighborhoods”. Plus, we will have a guided walk of the Heard’s Gardens before the meeting.

Texas Discovery Gardens

Presentation Summary

We often hear, “My HOA won’t let me plant native plants.” The fact is, Texas state law prohibits HOAs from disallowing water-wise landscaping but does allow them to require that landscaping fit the neighborhood’s general aesthetic. How can we encourage the use of more native plants in our community while keeping HOAs happy?

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
