This cactus is 3 m tall! However if you cut it shorter it will branch out and keep growing (see photo 3.) it will also produce 'babies' that can be planted. As well as the really tall barrel this cactus has a smaller growth at the bottom (see picture 2) Not sure of the variety but it's the kind they make 'rain-makers' from. It's very spiky!
Comes in an earthenware pot.
