The plant forms a huge caudex that is filled with tunnels and chambers. There are smooth chambers and rough chambers. The smooth chambers are where the ants live and the rough chambers are where they put their garbage and excrement. The ants have a warm, dry home and the plants receive nourishment from the waste products. A win/win situation for both the plant and the ants.

Of course, we have no ants in our plants (or pants) when we grow these in our homes, but in their native habitats, the ants are definitely in the house(plant).
