Since we are on the subject of mystery Aloes, does anyone want to have a go at identifying this one? It looks like it has a lot of the characteristics of A. chabaudii, in terms of the flowers and the darkening of the leaves in the Fall/Winter, but of course A. chabaudii is not spotted/speckled and has somewhat larger teeth. I have not been able to find a matching speckled/spotted Aloe, so am suspecting some kind of hybrid, but I mostly have literature for the southern African Aloes, not the central and eastern ones, so I guess I have not exhausted the options that it is a true species. It has been a prolific bloomer, sometimes it has two to three generations of flowers over the winter/spring. This year it started blooming late November which is incredibly early (previous earliest pictures with blooms were late January/early February).
I got it in the winter of 2007 and it has steadily grown from 1 rosette to a nice clump of multiple rosettes with many different flower stalks and it has survived any freezes during that time quite well.
Thanks Palmbob. After seeing all the other articles you wrote for DG on Aloes I should have searched for Spotted Aloes to get to the article you wrote on them. I looked at A. macrosiphon, indeed looks like it captures the leaves and coloration of the plant quite well, but the flowers are definitely a little different, the individual flowers stand off from the stalk more than those of A. macrosiphon, so maybe some form of hybrid.
