Does anyone grow/has/heard of this one? I found a rooted cutting on e-bay and bought it. The flower shows black and I thought it was interesting to try.
I paid $11.20 + 14.99 shipping, so it is not too expensive if it turn out to be not true.
Dark-Maita plumeria.
might take a few years before you figure out what you have. If it dies you have not lost much
