Yeah, that's what they called it, when I bought plants last year. But look at those leaves. Dahlia leaves. It even makes little tubers like dahlias.
I think some botanist mis-classified it, and they just haven't got around to looking at it again yet. It's no big deal, lovely plant I wish I could grow here . . .
I grow orchids now, and the crazy orchid gurus are changing classifications all the time on orchids.
