Desert rose (Adenium obesum) is not a rose that grows in the desert, nor is it closely related or similar to a rose. It's actually a succulent flowering plant in the dogbane family.
The plant is a slow growing tree that has a thick trunk and waxy coating, so it can retain more water in a dry environment. The plant originates from tropical areas of eastern Africa, which means they need to store more water to survive in dry climate. Plus, the plant produces few flowers a year so it can save more energy.
Its flowers are usually pink or red. When you grow a desert rose plant, make sure it gets full sunlight and only water it when the soil is dry.
Here are some photos of this lovely plant.
