What's In Bloom?

MONSOON
July - September

Trees that bloom in Arizona’s rainy season are responding to increased moisture along with intense heat. Rains often stimulate insect hatches, insects which may be important pollinators (or serve as food for pollinators such as bats). Rain also allows an increase in foliage; many trees put on most of their canopy growth in the warm wet season.
