    I have two of these plants, bought two years apart. The first one did not come back yellow this year. It was a pale pink. It seemed to be the original plant that overwintered, but perhaps the original plant did die and whatever came back was from seed. I don't think this is the case. I am not a fan of the mutation, but I kept the plant anyway to see what it does next year.

One specimen (north of Shantung) is blooming. 2nd specimen is barely showing any growth. Too much water perhaps?
