James, I looked pretty thoroughly on every plumeria informational site I could think of, and I could not find a single mention, much less a photo, of roots growing on the trunks of trees. Perhaps this is something seen in S. FL, but I sure don't remember having ever seen even a single root form the way Sandi's tree has done.
I am waiting for
@Dutchlady1 to tell us what becomes of those roots. This is sure an interesting phenomenon, at least to me.
