Plant Hardiness Zones in Southern California

Areas in Southern California Where Plants Are Most Likely to Thrive

Not all plants thrive under the same temperature and climate conditions. Therefore, it is important to know your state’s climate zone so you know what plants you can successfully grow there. Most gardeners use the USDA Hardiness Zone Map to determine what plants thrive in a specific location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Below is the growing zone for Southern California. Southern California contains different types of climates: Mediterranean, semi-arid, desert, and mountain. Southern California has warm to hot summers and mild winters. Depending on the area, rainfall is rare or moderate. The time in which you should plant your seeds or transplant them outside depends on what planting zone in Southern California you live in. We recommend growing lettuce, brussel sprouts, cabbage, and kale here.
