I have come across pictures that look like yours (If the the one I'm thinking of is the one your referring to) as 'Pink Allusion,' but then there are pictures of mine also with the name cultivar name. That makes IDing the plant confusing because I'm not convinced that what we have are the same plants. At least I'm not convinced yet.
I used to have one that had pink leaves, but they never turned green.
