There exist five distinct types of Desert Rose, all originating from arid or semi-arid climates. However, they are capable of adapting well to tropical and semi-tropical environments as long as they receive ample sunlight, heat, and well-draining soil. The Desert Rose flourishes in direct sunlight with temperatures of at least 70°F and can tolerate temperatures up to 100°F. In cooler environments where temperatures drop below 40°F for extended periods, the plant blooms abundantly during the warmer months and attracts hummingbirds, bees, and butterflies. When the weather turns cold, it’s best to bring the Adenium indoors to enjoy during the winter.
The flowering desert rose thrives in full, strong sunlight and will bloom beautifully when given this environment. Although bright morning or afternoon sun is also suitable, the plant may not flower as heavily. These plants become weakly stalked and bony if kept in the shade. While strong sun stimulates flower production, the desert rose takes a break during the hottest and wettest months of the growing season, resulting in two periods of flowering. If the plant receives the right amount of light, it should bloom steadily until mid-summer before taking a 6-8 week pause and resuming flowering in early autumn.
During hot weather, water moderately, but during cold weather, cut back on watering. The roots must never become waterlogged, and it is best to think of the Adenium as a tropical plant in spring and summer and a cactus in fall and winter. During the growing season, check the soil every few days in container plants, and when the soil is completely dry, water slowly and carefully. The soil should be moist, not wet, with no standing water. Use a well-drained soil and allow the mixture to dry out thoroughly before watering again. Adenium planted directly in the landscape should be placed on a slope so that water can run off after heavy rains. The Desert Rose outdoors is very drought tolerant and may not require water once established. In times of extreme drought, water deeply, sometimes with a slow drip for several hours during the coolest part of the day.
