Peniocereus gregii. Considered rare in this area, the Desert Night Blooming Cereus is difficult to photograph. The blossoms open only once, after dark, and close at first light. Moreover, because this cactus cannot support its own weight, it always grows inside another “nurse plant.”
This photo was taken with the aid of a bit of flash and a pocket LED penlight. Worth the wait, though…

Stunning! I’ve never seen them in bloom, and they are sometimes in these parts if you know where to travel. I still remember the plants of this species you showed me last Thanksgiving!
Oh, well done. Just getting any old photo of one of these babies is an achievement but you’ve gone further. A photo to be proud of .
