Regions / Western States
A plant's performance is not only governed by its hardiness or heat tolerance but also by many other factors such as the length of growing season, timing and amount of rainfall, winter lows, summer highs, wind, and humidity. Sunset Magazine has developed a Climate Zones map, which takes all these factors into account and has long been the standard among gardeners who live in the 13 western states. Unlike the U.S.D.A. map which tells you only where a plant may survive the winter, the Climate Zones map shows where that plant will thrive year-round.
