Agave americana
Genus: Agave.
Species: Agave americana.
I have one of the variegated forms, not sure of exact cultivar name as the original plant was an offset donated by my mother. I usually leave it outside all summer, unheated greenhouse in winter. I may consider leaving it outside in winter this year, but I'll keep it in a container rather than planting it out as I suspect it will hate having wet feet all winter in my clay soil. Snails eat the leaves, or try to, leaving unsightly notches which is why the lower leaves have been cut.
