Description
Adenium obesum subsp. boehmianum, also known as Adenium boehmianum, is a slow-growing shrub or small tree with barely succulent stems and only modestly fat roots. Leaves are glossy green, club-shaped, and up to 6 inches (15 cm) long. They are the largest in the genus. Flowers are trumpet-shaped, up to 2 inches (5 cm) in diameter, and appear in summer. They range in color from white and bright pink to crimson red with a dark purple throat.
Hardiness

How to Grow and Care
These are not difficult plants to grow well if they get enough sunlight and warmth. However, like all succulents, they cannot tolerate sitting in water and if you err, do it on the side of too little water. Use a specialized soil mix designed for cacti and succulents.
Repot as needed, preferably during the warm season. To repot a Desert Rose, ensure the soil is dry before repotting, then gently remove the plant from the pot. Knock away the old soil from the roots, removing any rotted or dead roots in the process. Treat any cuts with a fungicide and antibacterial solution. Place the plant in its new pot and backfill with potting soil, spreading the roots as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
