Based on the size, leaf shape, etc. on these, I figured that's what
they were, but I didn't want to take a chance on IDing a ping with
something more substantial. That leads me to another question,
though. What sort of conditions does _P.caerulea_ require? I've been
keeping them quite warm under fluorescent lights for most of the
winter; I hope I haven't kept them from going into dormancy. Could
these reddish leaf formations at the center be winter rosettes?
