Hello LindaMcGill, thank you for joining us.
I am not familiar with which plants would do best in south Texas, but I will try to suggest some that I think will work.
You already have Mesquite and Anacua, very good trees, but Chinaberry is not native and is on the Texas invasives list.
You might try to add these Trees.
Pecan, Cedar Elm, Texas Mountain Laurel, Roughleaf Dogwood and Mexican Buckeye.
Shrubs
Rock Rose, Turk's Cap, Texas Kidneywood, Barbados Cherry, Texas Lantana, Salvia gregii, Flame Acanthus, Zexmenia,
Western Ironweed, Heartleaf Hibiscus, Red yucca, Skeletonleaf Goldeneye, Texas Sage.
Button Bush is very nice but it loves water.
Vines
Crossvine and Coral Honeysuckle.
Here is a link to recommended plants for South Texas from the Wildflower Center.

I hope this list helps.
Work hard and have fun!!!
Josephine.
