It is a scrambling shrub, able to grow up to 3 m tall and with a spread of 2 – 3 m wide. Leaves are obovate with crenulate margins, up to 25 mm long, thin and light green in color. The leaf axils are winged with ear-shaped appendages at the base of each leaf. Another salient feature is the abundant axillary growth of leaves, resulting in many leaves of varying sizes being found all over the plant, and a distinctively dense and bushy appearance even in small plants. Flowers are white in color, borne on rounded terminal clusters.
Adenium is grown as a houseplant in temperate regions. Numerous hybrids have been developed. Adeniums are appreciated for their colorful flowers, but also for their unusual, thick caudices. They can be grown for many years in a pot and are commonly used for bonsai.
