The desert rose (Adenium obesum) is a striking plant with swollen succulent stems and deep red flowers. The plant is deciduous in cooler winters, but it can be kept in leaf provided there is sufficient warmth and light water. There is no part of these plants that doesn't command interest, from the dramatically swollen stems on older plants to the bright flowers to the tight clusters of narrow, green leaves. Beware, though, the sap of the desert rose is poisonous and should never come into contact with children or pets. If you get sap on yourself while handling the plant, wash your hands immediately.
Water: Water during the summer and spring. Reduce water in the winter, but keep hydrated enough to retain its leaves.
Temperature: Keep at least 50º at all times; if you keep temperatures of 60º or higher during the winter, the plant may retain its leaves.
Soil: A well-drained succulent mix, with an ideal pH around 6.0 (slightly acidic).
Fertilizer: Fertilize during spring and summer with controlled-release fertilizer or liquid fertilizer according to label directions.
