What is a hardiness zone?
Hardiness is the plant’s ability to withstand the rigors of winter. The Canadian territory is classified into 9 hardiness zones that range from 0 to 8. The highest numbers are for areas with the mildest winter. In addition, each zone is divided into two classes, “a” and “b”. Class “a” is slightly colder than the “b”.
An indicator for choosing your plants
You can grow perennials, trees and shrubs with the area number of your area or a lower number. For example, if you are in a 5b ranked area, you can plant the range of zone 5b plants or colder zones (5a, 4, 3, 2, etc.).
There are often microclimates within a given area. These microclimates are often favored by shelterbelts or by various other means. The layer of snow can also play a big role in plant survival during the winter. Snow remains the best insulation. It prevents the soil from freezing when it arrives early and it protects from the cold parts below its surface.
When there is snow and you are in a microclimate, it is sometimes possible to plant plants from higher areas in a lower zoned area.
