Spring is here and the Joshua Trees are blooming!
The Joshua tree typically grows in the Mojave Desert, in southwestern North America. They grow on average 3 inches a year, although because its trunk is made of thousands of small fibers, it lacks the typical tree rings, making it tough to determine its exact age. We do know that it can live for hundreds, if not thousands, of years.
The flowers don’t bloom every year, but when they do they can be seen at the ends of the sword-like evergreen leaves from February to late April. Once they bloom, the trees are pollinated by the yucca moth. Wildfires can be devastating, since the moth will not find it advantageous to pollinate trees left isolated by fires, but prefer instead to pollinate within tree clusters.
