In the meanwhile - Dave, you asked how many Adeniums I have. I have three. I have a regular obesum, a multiflorum Mombassa, ( this one is somewhat miniature) and the third one is perhaps a somalense x obesum. That one grew very fast and very tall and had a trunk more typical for somalense, I used to top it off at eye height. I almost lost it a few years ago, but I took some cuttings and they took off again.
Seeds resulting from these three might give small, medium and very fast growing plants, as I have these outside in Summer blooming next to each other.
And - your name is on those seeds.
