Adenium somalense - 5 seeds


Adenium somalense occurs in Somalia, Ethiopia, Kenya, and extends a bit into adjacent nations. The most popular form in cultivation grows a tall, conical, succulent trunk, but there are also shrubby forms with subterranean caudexes. Only A. arabicum (some populations) and socotranum have larger caudexes. The flowers are rather small especially considering the size of the plant. The most identifiable characters are the conical caudex, light-colored veins in the leaves, and nectar guides that extend onto the petal bases. This species is extremely intolerant of cold. Temperatures below 50° F (10° C) for a few weeks will usually cause the roots to die and the plant will topple.Even keeping the plant dry in winter will not reliably prevent this collapse. Probably for this reason and because of its large size it is not common in cultivation.

These are not difficult plants to grow well, provided they get enough sunlight and warmth. Like all succulents, they cannot tolerate sitting in water.
Use a specialized soil mix designed for succulents and cacti.

Light: Full sun - sunny window.
Water: Water during the spring/summer. Reduce water in the winter, but keep hydrated enough to retain its leaves.
Soil: A well-drained succulent mix, with an ideal pH around 6.0 (slightly acidic).
Fertilizer: Fertilize during spring and summer with controlled-release fertilizer or liquid fertilizer according to label directions.

Repot as needed, preferably during the warm season. To repot a succulent, make sure the soil is dry before repotting, then gently remove the plant from the pot. Knock away the old soil from the roots, making sure to remove 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 out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
