Thanks. Good links! After a close look at the plant, it looks like
it has thorns but it actually does not.

Its called a caudiciform.

Adenium obesum is a member of the Periwinkle family (Apocynaceae), closely
allied to the Oleander (Nerium oleander), and has no thorns nor spines on
the stems.

The common name "Desert Rose" is a bit of a misnomer because there is
absolutely no comparison with a rose. "Desert Rhododendron" would have been
more appropriate because of the flower resemblance. One of its other common
names is "Mock Azalea".

It normally goes dormant in winter and can be expected to bloom in the
summer with the proper treatment.
