Well, what we have established is that I never had xenia, it (the one in question) grows really slow, I had a (rescue) devilshand in the exact same spot that I completely forgot about and it most likely that that's growing back.
I can think of a few logical reasons to think it is indeed the devils hand regrowing, but 2 people come forth and say xenia.
If you had indeed read the whole post and you still think it's xenia, I was curious as to why...
