Got a massive cactus for $2 from a garage sale November 2011.
This cactus is about 7 feet tall and looks ominous at night.
Despite its didgy base which seems to be getting thinner this cactus just keeps getting taller and taller.
Definatly looking healthy at the top but the base is still really rotten looking. Will have to get a photo of it.
Seems to be growing, hard to tell, but i think its added several inches to each of its top horns.
