Cool plant! I just ordered some Adenium seeds, think it's the same species. Any growing tips for early blooming? It's always fun when the size of the flower dwarfs the plant itself. Some of my cacti are like that.
They get moved to full sun after their first set of true leaves. I use a 15-9-12 9 month formula osmocote on the soil and feed with a mild solution of 20-20-20 water soluble about once a week. I don't fertilize when they are predicting cold cloudy weather.
