Can you ID a Cactus?

Q: Please identify this cactus plant. I purchased it at a drugstore without a "name tag" but did have two fake flowers attached' Thank You, John J.

A: John,

Your cactus is a Cereus hildmannianus monstrose, or commonly called 'Fairy Castle'. It is a dwarf mutation of Cereus hildmannianus (which grows to tree size) and is native to southeastern Brazil and northern Argentina. Your plant will stay small and have many branches. The largest Cereus hildmannianus monstrose I have ever seen was only six feet tall, though I have seen the non-mutant species about thirty feet tall.

Good luck with your plant,
Hap

Oy, that's tall.
