Build up the soil prior to planting by mixing in an inch or two of compost in a wide area around the plants, not just the planting hole. Your County Extension Office has free information on the best plants for your area. Their contact information is:

San Antonio, TX 78230
For some tough plant suggestions to get you started I suggest Yellow Bells or Esperanza, Salvia 'Indigo Spires', Salvia greggii, Purple Heart, Burford holly, Cenizo or Texas Sage, Crape Myrtles, and for an annual flower try Narrow Leaf Zinnias or the regular garden zinnias (not so tough but fast and beautiful, just keep watered).
Thanks for the question. Please stop in again soon!
