Native to arid regions of Arabia and Africa, desert rose (Adenium obesum) is a caudiciform (“fat plant”) prized for its grotesquely swollen, water-storing trunk (caudex) and spectacular 1–2 inch saucer-shaped flowers in red, pink, or white. Sparse, small leaves appear only on new growth. Indoors it reaches 2–5 feet tall and 1–3 feet wide.
Provide maximum light (south window), a fast-draining cactus mix, and water only when the soil is bone-dry. The caudex should sit partly above soil level to prevent rot. It’s nearly impossible to kill if not overwatered. Dormant in cool, dark winters—reduce water to a bare minimum.
The sap contains cardiac glycosides; highly toxic if ingested. Keep far from children and pets; wear gloves when handling.
