Probably the most basic factor in selecting the right plants for your landscape depends on the region in which you live.
The USDA divides the United States, including Puerto Rico, into 13 regions, or Plant Hardiness Zones.
These zones are defined by an area’s average low temperature and are separated by a difference of 10 degrees Fahrenheit. Zone 1 is the coldest region with an average low temperature of -60 degrees Fahrenheit and zone 13 is the warmest region with an average low temperature of +60 degrees Fahrenheit. These zones can be further divided into “a” and “b” with a difference of 5 degrees Fahrenheit.
The USDA Hardiness Zones are divided according to average low temperatures since they represent the minimum temperatures a plant variety can withstand to survive. This means that it is most hardy in temperatures that do not drop below 0 degrees Fahrenheit.
Though the USDA Hardiness Zones provide reasonable guidelines when selecting plants for your area, it’s good to remember that they are only guidelines – there are always exceptions and other factors to consider if you really want to grow a plant variety just outside your zone.
Most likely a plant that is hardy in zone 8 – 10 will not survive a zone 6 winter since there is a 20 degree average low difference, but you may find success growing a zone 8 – 10 plant in zone 7 or a zone 7 plant in zone 6.
If you’re growing a plant variety in a slightly colder region than recommended (or even if your region is experiencing colder than usual temperatures) plan to use extra winter protection by adjusting the watering schedule, spreading additional mulch, and covering the plant with breathable material.
You can also grow plants in containers and bring them indoors for winter. Test it out by planting one of our Encore Azaleas in a container and bringing it indoors for winter. Place the container near a light source, e.g., a window or lamp, but make sure it doesn’t get chilly! Once spring comes, take your Encore Azalea container back outside and watch it thrive. See "Container Planting Encore Azaleas" for more information.
