As far as I know, Adenium plants have the capacity to be re-grown through cuttings of the mother plant. I tried the last time, but did not bother to take care of it well. But this time, since I had success growing my banyan plant from the mother plant’s cutting, I wanted to try the same method on Adenium as well. After a week, the bigger leaves dried away, and I just assumed the cuttings will take time and left it at that. Now I see new growth in the leaves, but no new roots. I do not want to jinx this or anything, but I am beginning to think that Adenium cuttings can sustain growing in water. Time will tell.
