Find your growing zone

Enter your city or town to find your Canadian hardiness zone.

Perennials and trees

Compare your Canadian zone with the plant’s hardiness rating. Canadian and USDA zones use different scales.

Annuals and vegetables

Use local frost dates and the seed’s growing instructions to plan when to sow.

Your garden’s conditions

Sun, soil, drainage and shelter also affect how well a plant grows.

About this finder

This finder uses Natural Resources Canada’s 1991–2020 hardiness map and Canadian place names. Each result is an estimate at a mapped point, so zones may vary across a city or town.

Searches run in your browser. The location button asks your browser for your position; OSC Seeds does not receive or save your coordinates. Your browser may use a location service. Your selected location is remembered only in this tab.
