4.5" Adenium Desert Rose
Adeniums are succulent, tropical plants. They are distinctive among the class because they develop a caudex, or swollen trunk. All succulent plants have some sort of water storage system, be it leaves, stems or roots. In desert rose, the trunk swells to conserve moisture for times of drought. A nice fat trunk is an indicator of plant health. A skinny stem can indicate that the plant requires more moisture.
An interesting bit of desert rose plant info is its natural resemblance to a bonsai plant, with a short stature when mature, and tidy canopy perched atop the graduated stem. Many growers seem to have trouble caring for desert rose plants, but these can truly be easy to maintain if you keep in mind the water, temperature and lighting needs of Adenium.
