Cactus Flowers

Not sure if this belongs here but I woke up to the great pleasure of the rare overnight cactus bloom.

Wow, is that a dragon fruit lurking behind your other cactus? I wouldn't expect an organ-type cactus to have that large of flowers coming out the sides.

They're only here for one day... One night really... Once the heat comes they're gone.

No dragon fruit unfortunately. I have two plants and I don't know where to put them. I'm considering letting my black sapote tree grow up so the dragon fruit can climb the sides, now that would be a spectacle. For now they're potted hanging off a pair of wooden steps so they can grow over. They're still quite young.

I think what you are referring to is an unblossomed flower! Maybe it will come out tonight.
