Agave celsii

Syn Agave micrantha 

This is a small colony forming agave with dark green rosettes and leaves edged with neat rows of tiny dark teeth.  It seems to love the growing conditions in the southwest - enjoys the high rainfall but doesn't enjoy low temperatures.  It also flowers quite regularly too.  Not sure how it will grow in colder areas.

Agave celsii var albicans

A heavily glaucous almost white variant.
