What’s my Zone?

“The 2012 USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones.”

USDA Plant Hardiness Zone Map

The USDA Zone Map gives you a snap shot of your area. USDA provides the average low temperature for your region. It can help determine if the plant your considering will survive the winter in your area. Although, it does not help determine if that same plant will survive the summer. According to the map, Intermountain Nursery is in Zone 9b. For a more in depth look at your own micro-climate, look to “Sunset Climate Zones”.

A plant’s performance is governed by the total climate: length of growing season, timing and amount of rainfall, winter lows, summer highs, wind, and humidity.
Sunset’s climate zone maps take all these factors into account, unlike the familiar hardiness zone maps devised by the U.S. Department of Agriculture, which divides most of North America into zones based strictly on winter lows.
