There was some debate on here whether Plant Delights Nursery had the correct locality for these(Welfare, Texas) or if they even naturally existed that far west at all.

I dedicated some time after a roadtrip today into an attempt at locating them. I figured with everything turning red, orange, or brown they might stick out. A few Yucca, Nolina, and Dasylirion
