Hi saintlorilea,
When I looked at the photo of your plant, my first impression was that it was a Plumeria, although the vertical ridges on the stem are something that I've never seen before.
I took the liberty of showing your photo to a friend of mine,
she knows a LOT more than I do about Plumerias
and she felt the same as I did, that it looks like a Plumie,
but neither of us understands those vertical ridges.
Have you ever seen this plant flower?
