Thanks! We bought it when my children were little. Somewhere they had an assortment of cactus plants meant to appeal to kids with different types of cacti having plastic wrappers with cartoon-like drawings and character names on them—so that's where I got the "monster" cactus. But the monster description does fit the plant well. :-)

It does indeed look similar to the Cereus peruvianus, though the growth pattern seems a little different.

I have one I bought a year ago n I think it's just beautiful. I plan on buying another..

Glad you have one! :-)

Hey Donnie, just as a time reference how old are those kids now?

25 and 31 :-)
