i have tried on several occasions to grow the winter-hardy varieties, and each has met with death. I have a front yard that I made all sand and gravel to a depth of 12 inches to have great drainage. I have a great variety of plants from sagebrush to imbricata and ball cactus, rabbit brush, that have grown well for 6 years, but the agaves have not fared well. I am not sure if it is still the moisture or other reasons. We have banana yucca and red yucca that has survived here but does not appear to get any larger than when they were planted. Would anyone know the reason for this, as well?
