Despite the difficult soil and weather conditions gardeners encounter on the Texas High Plains, we don't lack in the number of plants that can thrive quite well, many with only monthly moisture supplementation. I've compiled lists of annuals, perennials and bulbs, grasses, shrubs, cacti, agaves and yuccas. This is not by any means a complete list. I may have left some of the more common and traditional plants off the list, but hopefully, as time goes by, I will add more. For many of the plants listed below, there are other varieties, cultivars or hybrids that work equally well – as well as some that do not. I apologize in advance for not being as complete or thorough as you might wish. But I don't believe there is any one source or list of plants one could turn to to learn whether it is suitable for our climate. And indeed, more and more species, varieties, cultivars and hybrids come on the market each year.
