Ken, it was my fault. A landscaper not familiar with plumeria took the initiative to hard prune it when it wasn't neccesary. At least not the way he did it, anyway! All I wanted was my grass cut.
Usually I don't let any of my plummies be touched by other people, just me.
Anyway. Pudicas grow so well here in S. Florida, with very little care. It kept producing lovely blooms until the mishap. At any rate, I'm happy my TLC is paying off, finally.
