Adenium or Desert rose is a sun-loving plant, so grow it in the brightest spot you have. It's equally outstanding grown in landscape beds or borders as it is in containers and planters on decks, patios, and other outdoor spaces. Water it sparingly; in many areas, summer rainfall is enough to keep the plant flourishing in all but the worst drought conditions. Fertilize it in spring and summer, if you wish, with a general-purpose fertilizer. Because desert rose is a slow-growing plant, pruning is not necessary. Note: Adenium is not meant for human or animal consumption. All parts of this plant are considered poisonous.
