Invasive Plants & Alternatives
BC is a large and diverse province with a variety of growing conditions. There are currently two systems used for classifying hardiness, the Canadian Hardiness Zone and The United States Department of Agriculture (USDA) Hardiness Zone System. The information provided here is based on the USDA system due to its current extensive use by gardening enthusiasts, commercial horticulture, and industry professionals.
Zones are based on the annual minimum temperature; zone 1 is coldest, zone 9 is warmest. Select your region and/or specific zone to:
- INVASIVE PLANTS: learn about horticulturally invasive plants that thrive in certain zones to avoid/replace; and
- ALTERNATIVES: find expert-recommended alternative, exotic and native plants to choose instead
