Newfoundland and Labrador Plant Hardiness Zones

Hardiness zones, also called growing zones or planting zones, show which plants can survive the winter in a given place. The zones on this map are Canada's plant hardiness zones for 1991 to 2020, published by Natural Resources Canada in 2025. Canadian zones combine several climate measures, including winter low temperatures, the length of the frost-free season, rainfall, snow cover and wind, so the temperature range shown with each zone, its extreme minimum winter temperature, is a guide rather than the whole definition. The previous edition, based on 1981 to 2010 data, is still available: Newfoundland and Labrador hardiness zones, 2010 edition.
Under the 1991-2020 zones, Newfoundland and Labrador spans 13 hardiness zones, from zone 0a (-56.7°C to -53.9°C) to zone 6a (-23.3°C to -20.6°C). Of the 232 cities and towns listed below, 74 are in zone 5a, the most common zone. St. John's is in zone 6a, Mount Pearl is in zone 5b, Corner Brook is in zone 5a.
