Wildbloomers,
Thank you so much for your elaborated answer, much appreciated, very helpful. I guess all I have to do now is to wait for it to bloom. I will upload a photo when I will have one (in spring). The wire trained around the stamp is for support. When I bought the plant it was in a very bad shape. I loved it as it was different visually from my Adenium Obosum and Swazicum.
