Hardiness zones in southern Ontario

The range of Plant Hardiness Zones in Canada is reflected in the colours used. At a glance, you can appreciate the subtle but important differences.

For example, in the Ontario sample at right you see the colder zones are in the green colours while the warmer zones are in browns and the colour of terra cotta pots — such as zone 6b near Windsor and St. Catharines.

      Not sure why part of the province is cut off in the map. Will need to update. Thanks for letting us know.

    Apparently Agriculture Canada doesn’t think Pelee island or Point Pelee exist? Would they be 6b, 6a or even 5b??
