Adenium Arabicum
IntermediateAdenium arabicum
An Adenium with wide spreading caudex, more caudex-focused than obesum, popular with collectors.
About
Adenium arabicum is native to the arid regions of Yemen and Saudi Arabia, closely related to A. obesum but distinguished by its broader, more dramatically swollen caudex that spreads outward rather than growing tall. The trunk has a rough, grayish-brown texture and develops a highly sculptural form with age. Leaves are thick, glossy, and dark green, generally larger than those of A. obesum. Flowers are beautiful shades of pink to red. Growth tends to be slightly slower than A. obesum, but the caudex becomes more impressively massive over time. Full sun is essential—sunlight exposure directly influences caudex development. It is particularly prized for bonsai-style cultivation and the practice of exposing the roots above soil level for dramatic effect.

Growing Tips
Light & Placement
It prefers full sun, and the caudex fills out in proportion to the light it receives. Give it a sunny outdoor spot.
Watering
From spring to autumn, water thoroughly once the soil dries. Withhold water in winter and let it live on moisture stored in the caudex.
Temperature & Overwintering
Overwinter indoors in a bright spot kept above 10°C. Dry soil plus warmth keeps the caudex sound through dormancy.
Soil & Repotting
Use a well-draining mix. For an exposed-root style, lift the caudex a little higher at each repotting.
Pruning & Shaping
It suits bonsai-style training. Cut back overlong branches in the growing season and shape it to show off the wide, spreading caudex.
