What does your Zone number mean?

Your planting zone number indicates the annual minimum temperature in the zone's designated area.

For example, Zone 5' minimum temperature is -25 degrees Fahrenheit/-28.9 degrees Celsius.

Before buying any rose, check to see what Zone is on its label. If a rose has a Hardniness Zone 5 designation it should be able to survive temperatures less than -25 degrees Fahrenheit/-28.9 degrees Celsius.
