Hetty, where did you get these?
I have a double white that's fragrant occasionally, at its' whim, but just faintly. I have a Siam Adenium double pink that's doing poorly, hasn't bloomed yet. The three are all doing poorly, I believe the trip was too much for them.
One person in the Yahoo group claims a strongly fragrant plant, I'm going to go steal the plant!!! But she'd someplace in Florida, maybe I can send Jim...
Congrats on those pretty plants, Hetty!
