Family: Apocynaceae.

A. obesum. Common name(s): Desert Rose, Impala Lily
Adenium Genus of about 5 species of perennial succulent from semi-arid regions of the Arabian Peninsula and E. to S.W. Africa. The true species forms a caudex at an early age, tends to naturally branch and flower at an early age. Flowers range from pink to reds with even a white form in nature. A highly variable species with many regional forms and varieties. Just remember a small pot with excellent drainage is a must. Do not over-pot and allow the plants to dry out between heavy waterings. Adeniums need bright light if they are to flower. Most hybrids and species start blooming in the spring when the conditions are warm and days start to increase its length. Many continue blooming through the fall and winter (in warmer climate zones). Light quality is very important. Bright filtered light is best. In areas of too high light intensities, more shade may be necessary, but in areas where light is not as burning, plants may be kept outdoors unprotected. Please note that the caudex (the swollen base trunk) is very susceptable to sun scalding. Protection by a smaller shrubby succulent growing at the base of the pots will help shade the trunk. Adenium
Growing conditions Watering and misting Propagation
Keep the plant warm - minimum 60F in winter. Direct sun is essential. Water moderately from spring to autumn. Compost must dry out before watering. Water sparingly in winter. Misting is necessary. Take stem cuttings in spring. Use a rooting hormone and provide bottom heat. Young plants should be pot bound before transplanting. When placing in final containers, remove top roots from woody root mass and plant with the upper part of the main root ball above the soil line to expose the decorative, gnarled roots. Sow seed as soon as ripe at 70 F (21 C).

Desert Rose Adenium is beautiful; easy care does well in my back yard under a tree, some sun, water once a week. My plant is healthy and I can see some growth post 3 weeks. I use Miracle growth soil.
