Plant Hardiness Zones

Clicking on the map above will take you to the official versions of the hardiness and minimum temperature maps available on the Natural Resources Canada website.

As our climate changes, zones will continue to shift and may not always follow the expected patterns from one year to the next. Experimenting with plants outside of their traditional hardiness zones is known as "Assisted Migration of Plants."

Assisted Migration acknowledges the fact that historically, plants had tens of millions of years to adapt to climate changes. As our climate continues to change - and with increasing rapidity - growing plants outside of their traditional hardiness zone may afford them an opportunity to increase the chance they have for adapting to new climate patterns. Risks do exist when introducing new species to an area though, as they may out-compete the native species of that region (which may also be struggling to maintain their habitat and adapt to climate-changes).

All species in the store have a "Canadian Hardiness Zone" label.
