Garden centres free of invasive plants
The City of Calgary is pleased to partner with local garden centres in 2011 on an innovative program aimed at weeding out threatening invasive species from store shelves. Together, the businesses listed below and The City are making it safer for Calgarians to select attractive, hardy and non-invasive ornamentals. Each of these stores has signed up to be a Certified Invasives-Free Retailer.
How the program works
Through consultation and partnership with local plant retailers, Landscape Alberta Nursery Trades Association (LANTA), federal and provincial governments, The City of Calgary developed a voluntary invasives-free certification status for greenhouses and garden centres committed to providing Calgarians with a shopping environment free of recognized invasive species.
Whether you are a long-time gardener or relatively new to Calgary's growing conditions, you can easily help safeguard Calgary's parks and neighbourhoods by selecting non-invasive species for your yard. When selecting plants, make sure that you aren't inadvertently buying a species that is not only illegal in Alberta but likely to spread out of your garden and threaten nearby lands. Plants that find themselves on the Alberta Weed Control Act list have proven to be aggressively spreading invaders that are damaging to the environment and costly for farmers, municipalities and private citizens who are required by law to control them. No plant is worth sacrificing Calgary's rich natural capital, no matter how pretty!
For more information on damaging invasive species to avoid, see the list below of plants that Calgary Invasives-Free Certified Retailers refuse to carry in their stores or check out the Alberta Weed Control Act Regulation for a complete list of provincially regulated invaders.
