Annette, I don't think I've ever seen a pink Pudica. I have a lot of the white ones. I don't envy the extra work you have by moving your plumerias inside. I have a couple of the plumie trees outside, in the ground, and they are now beginning to look very "ragged". Quite a few leaves have dropped off and I've picked others off because of the underlying rust. Actually, I do have some extra work, because I pick up the fallen leaves.
Even though I live in sunny Florida, it's not unusual to get a few very cold nights. Then I bring out my frost cloths, because I have a lot of tropicals, orchids, succulents and cactus, etc. That is work I dread doing.
My plumeria trees are far too big now to be covered if/when the temperature really drops. Have to keep my fingers crossed now.
