There are a multitude of different cacti for your yard. It really comes down to what you like. I think some of the opuntias which are commonly called prickly pear including some without thorns. Barrel type cacti are also nice as are the Echinocereus. You may want to also include yuccas, aloe and agaves in you cactus garden.
Thanks for the question. Please stop in again soon!
