A desert bloom is a climatic phenomenon that occurs in various deserts around the world. The phenomenon consists of the blossoming of a wide variety of flowers during early-mid spring in years when rainfall is unusually high.

The blossoming occurs when the unusual level of rainfall reaches seeds and bulbs that have been in a latent or dormant state, and causes them to germinate and flower in early spring. It is accompanied by the proliferation of insects, birds and small species of lizards.
