The Mohave Desert is dotted with Joshua Trees – and is the ONLY area where they grow. Joshua trees can grow up to 40 feet tall and the branches jag every which way giving them interesting shapes. They are pollinated by moths.
Because of the uniqueness of the tree in the Mohave, there is even a Joshua Tree National Park where the Mohave Desert merges with the Colorado Desert … called very originally Joshua Tree National Park. Although we didn’t get to the park this time, Ken and I did visit it on one of our visits to California.
So no park, but we did see a lot of Joshua trees.
