This plant is found in Africa and can take a lot of drought. It is an ideal plant for the living room; it can be grown in the full sun, so a windowsill is no problem and it can take the dry heat of the central heating. It is very easy to grow from seed, but the seed needs to be fresh. It can germinate within one or two days. The more sun it gets, the quicker it will flower, possibly within six months.
Wild Adeniums are usually various shade of red, but occasionally white ones do appear. In Thailand, a lot of breeding has taken place and because of the inherent colour variation in the wild plants, a whole range of colours are now available in cultivation, ranging from white to very dark red and all shades in between. Efforts are now made to produce a true yellow one.
