The World of Trees
Welcome to an arboretum of approximately five acres in Sonoma County, CA. We are in USDA Zone 9b and Sunset Zone 16, receiving maritime influence in both summers and winters. The Petaluma Gap in the coastal hills increases our mildness in both heat and cold weather. Thus, the arboretum has magnificent trees that thrive in Zone 5, such as Fagus sylvatica, and those that shine in zone 10, like Banksia or Hakea. Choosing the proper spot is critical; some need expose to wind, some need protection.
