Adenium or Desert rose has become a popular ornamental garden plant.
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.
First, we need to remember that Adenium plants are native to regions with poor, gritty soil and hot, sunny climates. So, we can’t expect the plant to thrive in overly moist soil in a site with limited light. They are also not frost tolerant and will succumb to a freeze if exposed. The plant will not survive long if exposed to temperatures below 40 degrees F. (4 C.) but will thrive in temperatures reaching up to 90 degrees F. (32 C.).
Desert rose succulents like bright light, so a southern window exposure provides enough sun for the plants to flourish and bloom. In the garden, choose a sunny location that has some protection from noonday sun, as this can scorch the foliage.
