The growth pattern is similar to my Agave Kissho Kan, but mine is variegated. It's definitely an agave.

Agave potatorum is the species. 'Kissho Kan' is a variegated version that may be a potatorum hybrid. This one looks like the species.

very cool the way it is growing but my potatorum does not grow high like that...is that how it usually grows?

I think it's agave parryi var truncata.

No, I'm wrong. It's potatorum.

Ok, so Agave potatorum, thanks!!
