This Desert Rose plant had beautiful red blooms in the summer but when we had a tremendous down pouring of rain at one period, I think it drowned the plant. At one point, the stalk and base of the plant was so soggy, it felt like mush. I was ready to toss it out. Instead, I cut off all the branches and most of the mushy trunk then left it alone to see what it looked like after drying out. This is the result after several months of doing nothing.

Top petals are yellow with prominent thick pink (almost red) line in the center of each petal. Bottom petals are curled to form a circle. All of the petals have frilly edges. The lower part of each petal exhibits splatters of purplish-brown hue, giving it a striking contrast against the vibrant yellow petals. The top petals have a tendency to not fully open during hot summer months, causing the purplish-brown color to become more visible.

Talking about Adenium (Adenium obesum 'Desert Christmas'), GigiAdeniumPlumeria wrote:

'Desert Christmas' is a multipetal adenium. Not all blooms will have pollens but some blooms do produce thick healthy pollens. Since the petals are thick and the throat is deep, the easiest way to coax it to produce seedpod is via hand pollination.

Talking about Desert Rose (Adenium 'Red Dragon'), GigiAdeniumPlumeria wrote:

Red Dragon is a single petal adenium. All blooms produce thick healthy pollens. Since this produces big single petals, it is easy to make it produce a seedpod via hand pollination. For best result, this can easily be cross pollinated with double or multipetal adeniums.

Adenium Multiflorum stays leafless and flowerless most of the year. It is active and has flowers in winter time.
