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

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
