nope. I was tempted a while back and found a bunch of troubling details that made me shy to slap down the dinero. It is one of those more desert plants that spread its range into Colorado.. Many of them just can't handle our long range of hot humidity and no cool nights. I have tried on similar plants from New Mexico,Utah and they all do not do well for me. It is a beauty. My rubber rabbit bush died last year after a life of looking like hell. My friend grew them in OKC , but their summers are shorter, but wicked.. Hers still died and she manipulated her soil beautifully. Also these guys come from a sandstone soil and that is a whole lot different from a limestone base. Oops, slap me silly LBJ says "Limestone canyons" 3500- 8000'. CaC03 tolerance is high so that is good.All I saw was sandstone canyons. "Important Deer Browse" made me cross it off my list. I wasn't going to pay the HCG's high price for expensive deer food. I found a mention that Mexican cliff Rose P tridentata does not tolerate water on its leaves. Also a mention of Z4 - Z7. Put on top of our long hot humidity, I decided to pass . If you do get it and make me eat my words, I will be off to buy one too. It is a beauty. It is one of those that maKE me drive 800 miles there and back for a looksie at the landscape. P mexicana sounds like it will live in northern Mexico.

They are all from higher altitude and further west so "higher and drier" and cool nights do go hand in hand with that. If I remember college botany right there are 3 different variants of photosynthesis C3,C4, and CAM. One of those needs cool nights for some reason I no longer recall. Some desert plants do fine , especially in a pot with good drainage others are impossible

It sure is a pretty thing!

I can't find any plants online. Maybe ill buy some seeds see if they grow.

HCG used to sell them , but I see no longer. Great Basin Native nursery in Utah used to but their site is down. Good luck on your search
