David, I had bought a Brazilian Plume plant from a Conservatory that's was where the Scale came from. I finally tossed the plant maybe I had it a whole year and never did get rid of the scale. It would start looking good but then the scale would come back. I used all kinds of systemics and still couldn't get rid of them. Finally gave up.
@Cinta, I have either a Siam Ruby or Zebrina that has a few pups. I would be glad to share.
