There is a kind of flower called desert rose, also known as Tianbao flower. It is a desert rose in the genus Tianbao of the Apocynaceae family.

On the street in Wuzhou, Guangxi, there is a vendor selling a plant that looks like dead grass. The vendor introduces the plant to customers as desert rose. It is easy to grow and can turn into green after being soaked in water for four to six hours. Green, beautiful flowers will bloom in three to five days. The flower is shaped like a rose, hence the name desert rose. It was later confirmed that the desert rose is actually a fern called "Selaginella", which is very drought-tolerant. In the dry season, it will become yellow and wilted, just like withered grass. If the water supply is sufficient, the branches and leaves will It stretches and turns green again, so it is also known as the "resurrection plant", but it does not actually bloom.

Ordinary roses cannot survive in the desert.

Strictly speaking, the desert rose I am talking about can only grow near the desert. It is called desert rose because its origin is close to the desert. It cannot survive in a desert where no grass grows.
