What are the Flower Growing Zones in Canada?
Knowing which flower growing zones are suitable for your garden is essential so you can pick blooms that will thrive in your area. Canada’s flower growing zones range from 1a to 8b and vary by region. The further north you live the lower the zone designation.
For instance, zone 1a is found in the far north, zone 8b is in the south. If you’re looking for flowers that will bloom in zone 2a, for example, you can look for varieties that are suited for zones 1a-3b.
Keep in mind, different types of plants tolerate different temperatures, so make sure to check the hardiness zone of the plant you’re considering planting.
Often times you’ll find listings for perennials that not only give you the zone but also let you know if it’s a cold-tolerant or heat-tolerant plant. It’s also helpful to look into the type of soil and level of sunlight recommended for the variety. It’s important to note that although you can often find plants that will survive and even thrive in conditions outside of their ideal climate, they will require extra care. Knowing the right flower growing zone for your area will help you choose the perfect plants for your garden.

If you live in Canada, then you’re likely to have Zone 1a flower growing conditions. Zone 1a is considered the coldest zone in Canada and the coldest zone in the world. It covers northern areas of Canada such as Nunavut, the Northwest Territories, and northern parts of the Yukon Territory.
It’s also found in northern Manitoba, northern Quebec, and northern Ontario. In zone 1a, the average annual minimum temperature is between -50 and -40 Celsius.
Because of this, plants and flowers that can survive in this cold environment are the only ones suitable for planting in Zone 1a. Examples of flowers that can thrive in this zone are mountain arnica, arctic poppy, and purple saxifrage.
When gardening in Zone 1a, it’s important to remember that the growing season is quite short. The spring thaw and the autumn freeze come early and stay late, leaving a very small window for planting and harvesting.
It’s also important to pick flowers that are well adapted to the cold environment.
