Texas Native Plants that Love Full Sun Landscapes

The Texas landscape can be hot enough as it is, plants that are in full sun areas – those areas that get over 8 hours of sunlight a day- can really need to be able to take the heat. These native plants of Texas can all thrive as well as survive the heat.
