The western part of the park is filled with Joshua Trees that stimulate a visitor’s imagination with shapes resembling stick figures. The trees (actually yuccas) are pollinated only by yucca moths that lay eggs in the flowers. The larva feed on seeds as the fruit matures. The average lifespan of the plants is approximately 150 years although there is concern a warming climate is resulting in much shorter lives at lower elevations.

Experts tackle readers’ garden questions.

Q: I’m wondering if you can identify what is on several rocks in our frontyard in Wilton. They appear to be maybe tiny eggs of some sort; some are very clustered and others are spread out. But then when I crushed a few, it seemed to be nothing but dust. So, I guess it could be some kind of spore.
