Most nurseries will carry those plants although some are not in season right now. You have some great nurseries nearby but I think they are wholesale only. :( My biggest advice to you is to not buy from Lowes or Home Depot. Yes you can get some decent plants from them but nurseries generally have better product. There are other reasons but I'll leave it at that for now. Mortellaros(would definately recommend) in New Braunfels has a nice selection plus their prices werent too much higher than the wholesalers. Shultz(although I havent been there in years) used to carry a decent selection. I think they switched management since I have been there though.
