I live in East Texas and am putting my home on the market around mid-May. Do you have any suggestions for adding "color" to the front of my home in the way of flowers? The front of my home faces west, so it gets the hot sun. I already have schrubs in the front, but I need color. What flowering plants do best in the Texas heat and are the least expensive? If I had my "rathers", I would prefer a flower with a larger bloom to be more easily seen from the road. What do you suggest?
