Most heat-tolerant plants
I'm looking for plants with the highest heat tolerance you can think of, and I'm talking seriously hot. Like middle-of-death-valley-in-summer hot. I've recently learned that one barrel cactus type can survive in up to 156 degree fahrenheit (69C) heat, so you get the idea of what I'm talking about. Very hot growing conditions. Can anybody help me?
Thanks for looking, anyway.
