I should mention that I had several large seed horns busting out in late Fall/ early Winter on two of my Adeniums. I had three plants in bloom last Summer - my small Adenium multiflorum 'Mombassa', my regular Adenium obesum and my third plant which I regrew from cuttings. Now the latter was a very tall plant which I used to lop off at eye-height, and looking then at the trunk shape, I always thought it was probably a hybrid of somalense and obesum.
I am mentioning this, because you will most likely have some hybrids here, I would expect short to tall growing future plants.
I am thinking of
@Drdawg and others, are you interested in growing a flat from seeds?
I assume they can be shipped in a regular envelope wrapped in some soft paper towels?
If so, a self addressed envelope might get you plenty of future plants.....
