Tofi I had one that reverted to green. Only the Albo's revert. Thai Constellation don't. I planted my reverted one out in the yard on a tree and it got knocked back by a freeze, when the new growth came out, some of it was variegated....not a LOT but some. People have suggested that if you section up a reverted Albo, at least some of the pieces will resprout with some variegation
