Agave titanota (hort)

A medium sized agave that is extremely robust looking - very thick leaves, very pronounced teeth and teats - which should develop in maturity a heavily glaucous covering so as to appear almost white.  Looks lovely in the pictures, my seedlings are nothing like it at the moment.  The plants in culture are probably a hybrid or another species entirely - the real titanota is almost completely white it is so glaucous, but for now I will keep referring to the more commonly seen plant as 'titanota'
