I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Your question is really many questions in one. I will provide a few suggestions and then refer you to some additional resources for more assistance. A few good plants for most gardens in your area include yellow bells (Tecoma stans), various Salvia's, maiden grass, semi-dwarf crape myrtles, and Plumbago.
For more information and assistance contact your county extension office at 512-854-9600. The following website will also be very helpful:
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
