genus Wilcoxia

Confirmed! None of the former Wilcoxias tolerate the summer heat of Yuma, even when completely shaded. The native Peniocereus greggii hangs around and grows, but is finicky here. The Mexican species don't like the extreme heat, either.

However, most of the former Wilcoxias tolerate the winter cold of the Chihuahuan Desert perfectly fine (since most of them are native there) and grew beautifully for me in Alpine, Texas.

I have only been growing them since returning to
Texas and
I doubt Wilcoxia could have survived the heat of the low
desert near
the Salton Sea where we lived before. I found by experience
that very
few cacti can survive 120F+ high temps!
