San Diego Region

Selecting plants suited to the San Diego climate is a key step to success.

A plant's performance is governed by many climate related factors including the length of the growing season, the amount of rainfall, winter lows, summer highs, wind or humidity. Various initiatives have taken place to determine how well plants would withstand the cold winter temperatures (Plant Hardiness Zones) or when plants would start suffering from the heat (Plant Heat Zones). A more sophisticated approach has been followed by Sunset which defines Climate Zone Maps based not only on hardiness or heat tolerance, but also on precipitations, wind, humidity and various other climate related factors.

The region of San Diego lies in Climate Zones 7, 11, 13, and 18 through 24. If you know your climate zone, find the best plants or exciting garden ideas for your geographic area.
