Know your plant zones

To determine if a plant is sufficient cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number, the colder the winter. Santa Fe is rated zone 5, meaning our temperatures don't drop below -10 degrees Fahrenheit. However, some areas around your home, like a sun-free north side, could possibly drop below that number. You should plant the hardiest specimens in these areas. Similarly, some zone 6 plants can make it through our winters when planted in a sheltered, mulched south side location. Any plants rated zones 3-5 will survive our winter temperatures. It's always wise to stick with plants rated for the zone we live in.
