    This comment is about the former Adenium arabicum, a wide-bottomed Arabian form of the desert rose. This form is apparently considered a synonym of the type species of Adenium obesum, according to the CoL. I don't know the details. I will use the former name here.

    Adenium arabicum is a native of Yemen and Saudi Arabia, and it can be distinguished from the typical Adenium obesum based on a few features other than geography. The leaves tend to cluster at the top of stems and they are minutely pubescent. The stem is wider at the base and more bottom heavy in its general proportions.

    This plant has been used in hybridization with other forms of Adenium because of its shape (vegetative characteristics). When you raise it the right way, exposing the roots, you can arrive at a fascinating, otherworldly form where the difference between stem and roots blurs in a really attractive way. This is particularly popular in southeast Asia. Really old plants can be totally spectacular, almost unreal, especially in bloom.

    Like other Adeniums, this variant likes good drainage, full sun and warmth, regular water at a higher frequency during the leafy phase than during the leafless one. It does not tolerate cold but there's no problem in our zone 11 climate.

    However, our climate maxes out around 90°F and my plants do not put on much stem growth until we have temperatures in the 80s for several days. Otherwise the internodes are really short, which makes for an excellent form if your goal is for a fat-bottomed plant. Expect limited stem growth in cool climates.
