Plant hardinesss zone map
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 below 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.
