This succulent shrub features a distinctive swollen basal stem, known as a caudex, and leathery, spirally arranged leaves clustered at the shoot tips. It produces showy, trumpet-shaped flowers in shades of red, pink, white, or yellow, often blooming in spring and summer. All parts of the plant contain a poisonous milky sap, traditionally used as an arrow poison in Africa.
Where it works in Kilifi
Ideal for a Kilifi-coast garden, this plant thrives in full sun, requiring at least six hours of direct sunlight daily, though it benefits from some afternoon shade to prevent scorching. Plant in well-drained, porous soil, suitable for succulents or cacti. It serves as an excellent ornamental specimen, a striking container plant, or can be trained for bonsai.
Growing notes
Adenium obesum is a slow-growing plant that is highly drought-tolerant once established, storing water in its thick trunk. Water regularly during hot weather, allowing the soil to dry completely between waterings, and reduce watering significantly or withhold during cooler, dormant periods to prevent root rot. It is not frost-tolerant and prefers warm temperatures (above 10°C), with its poisonous sap requiring careful handling.
