Just to clarify and explain, based on what zuzu's comments.... Adenium socotranum (now known as a ssp. of obesa) is relatively new to cultivation and still not widely available (which would explain why it might be necessary to say "true" Soco when describing a plant, especially given the misuse of that term in the trade). No doubt there are people trying, but I've never heard of a hybrid or cultivar of socotranum, just the (sub)species. The main problem with the plant to preclude this (other than availability, which is becoming less of a problem) is that it is very slow, undergoes extended dormancy, and takes a long time to reach maturity.
