Most of my younger years were spent in the Salt River Valley and particularly in Phoenix, Arizona. Some of the most fascinating plants in this low desert area were the bottlebrush trees. This one is called a Dwarf Weeping Bottlebrush. The Callistemon are a genus of shrubs or trees in the Myrtaceae family. There are about 50 species of Callistemon and all originated in Australia. This particular plant we found in the Los Angeles County Arboretum.
