There is no such thing as Aeonium obesum. You mean Adenium obesum.

The popular common name "Desert Rose" is not really appropriate. It
looks more like it should be called "Desert Rhododendron" from the
appearance of the flowers.

There are many plants with inappropriate common names. That does not
detract from the fact that the common name of Adenium obesum is
"Desert Rose"
