Adenium

Adenium is a genus of flowering plants in the family Apocynaceae, native to Africa and the Arabian Peninsula. These plants are commonly known as desert roses or impala lilies. They are characterized by their succulent habit, often featuring a swollen caudex or stem base, which serves as a water storage organ.

Adeniums are popular as ornamental plants, particularly for bonsai and container gardening, due to their attractive flowers and interesting forms. Flower colors vary widely and include shades of red, pink, white, and combinations thereof. Hybrids are commonly cultivated to produce diverse flower colors and patterns.

The sap of Adenium plants is poisonous and has historically been used as arrow poison in some African cultures. All parts of the plant should be handled with care.

Adeniums thrive in warm, sunny environments and require well-draining soil to prevent root rot. They are relatively drought-tolerant due to their water storage capabilities. Propagation is typically achieved through seeds or stem cuttings.

Common species include Adenium obesum, which is the most widely cultivated species, and Adenium socotranum, native to the island of Socotra. Other notable species include Adenium swazicum, Adenium multiflorum, and Adenium boehmianum. Each species exhibits unique characteristics in terms of size, shape, and flower morphology.
