Hardiness Zones in Canada
Regional Gardening, Hardiness Zones, Canadian Climate
Be aware of the hardiness zone of your area before you decide to buy plants. Some plants might not survive over winter!
- Canada's plant hardiness map provides insights about what can grow where. It combines information about a variety of climatic conditions across the entire country to produce a single map. The original map was developed in the 1960's for trees and shrubs. Since then, it has been regularly updated, using extensive climate data and modern interpolation techniques.
- If you are planning to buy a shrub, perennial or tree, you need to make sure that this new plant will tolerate year-round conditions in your area. Therefore, to ensure your new acquisition will survive and grow year after year, you will need to compare the hardiness zone of your area with the hardiness zone of your plant (included in most North American reference books, nursery catalogs and gardening magazines describing plants).
- Keep in mind, however, that this plant hardiness map is mostly a guideline. It does not include micro climates, humidity, summer heat tolerance either.
If you are not sure which hardiness zone you belong to, please check the maps below:
