I have a bunch of leaf variegation in my plant collection, particularly red and purple, so it's a delight but not terribly surprising when a plant that lost its variegation regains it.
This, however, is something a bit different. Leaves from a Pachyphytum NOID I received as a "welcome back" cutting started rooting, and I was all like "Whoa, dude, you're pink."
And root they did, but I didn't really expect the whole pink situation! You can even see some little nubbins of what may be growing points around the base of the leaf as well.
I've read around the Internets and seen Pachyphytum with pink roots, as well as mention of the same with Kolanchoe, although I haven't found any sort of even semiauthoritative source that describes the pigmentation and why it's useful for the plant.
