Very nice. Is this a grafted plant? I have one of these which is quite solitary.

I think it is a plant which I dropped on the ground and broke off the stem at ground level. Like some others this has happened to (I don't make it a habit), the roots put forth a number of pups and ended up with a clump which looks better than the original plant (which rooted separately).

Esteban amigo, that's a nice clump you got there!!!
