The city in Sonoma County, California, falls within multiple plant hardiness designations. These zones, established by the United States Department of Agriculture (USDA), are geographic areas defined by average annual minimum winter temperatures.

For example, a plant labeled as hardy to zone 9 can withstand the minimum average temperatures experienced in that zone.
Understanding the local plant hardiness designations is crucial for successful gardening and landscaping. It allows for informed decisions regarding plant selection, minimizing the risk of plant loss due to cold weather.
