Photo: Joshua Tree Flower Panicle

Standing out vividly against the deep blue desert sky, a flower bud on a panicle emerges from the dark green, bayonet shaped leaves of a joshua tree.

There are a number of events which have to "line up" in order for a Joshua Tree to flower. Usually, a joshua tree only flowers after heavy rainfall, provided it rains at the right time of the year.

Prior to the heavy rainfall in spring, the tree requires a winter freeze not unlike some of the spring bulbs we plant in our gardens.

Once the joshua tree is exposed to these elements and the flower emerges on its panicle, the only thing left is for the yucca moth to lay her eggs and in turn pollinate the tree.
