Many gardeners in the southwest are perfectly satisfied with beautiful, ornamental plants and cultivate lush lawns despite the environmental consequences of doing so. Other gardeners, however, have moved to embrace pollinator plants that provide resources to bees and butterflies. And some have embraced the xeriscape approach, which uses indigenous plant life to minimize the need for water. But this is just the beginning. 

Plants with Purpose speaks to gardeners who are mindful of the environmental impact of traditional ornamental plants and offers twenty-five alternative plantings that are beautiful, viable, and functional. Whether edible, therapeutic, medicinal, or attractive to pollinators, the plants in this collection provide a pathway to a more environmentally sustainable and functional garden and landscape. From agarita (for jelly and tarts) to wild garlic (edible greens), this selection of plants is curated specifically for warm climates and are beneficial to the larger ecosystem. 

In addition to history and description, each plant entry provides basic information and care tips such as plant type, light/water/soil needs, size, bloom and time, fruit, and availability. Many entries contain recipes, tea ideas, and herbal remedies. This “secret life of plants” provides a counternarrative to the standard texts on gardening and landscaping. 

Illustrated throughout with 200 beautiful color photographs of plants in their various stages of development and showcasing their multiple applications, Plants with Purpose will encourage readers to experiment with their gardening for a deeper engagement with plant life and the environment. 

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.
