I have Adenium obesum and Adenium mombassa multiflorum, but they stay small.
I bought this one as a small plant, but it took off right away and grew really tall. For years I topped it off regularly about eye - level, but lately I let it grow higher.
Looking at pictures of Adenium somalense, mine has the same typical trunk but the blooms are not quite correct. That's why I think it is maybe a hybrid somalense x obesum, or something like that.
