Be a PLANT WISE gardener and stop the spread of invasive plants.

Guide to PLANT WISE Gardening

Make good choices.  Purchase and grow non-invasive plants.  Select the right plant for the right place.

Replace existing invasive plants in your garden with non-invasive plants

Properly dispose of invasive plants.  Remove invasive plants before they flower to prevent seed spread.  Either burn them or bag them for landfill disposal.  Never dispose of invasive plants “over the fence” in natural areas or parks.  Never compost invasive plants!

Check reliable local sources before you plant.  Do your research. Ask your local garden centre or ask a local horticulture expert. Check out

Trade only plants and seeds you know are non-invasive.

Consider native plants. Use local suppliers only. Check out theAlberta Native Plant Council website

Avoid collecting pretty “wildflowers” from roadsides or natural areas.  Many are highly aggressive invasive plants.  Allow true native plants to thrive in their natural setting.

Avoid pre-packaged wildflower mixes unless the contents are identified and contain only non-invasive species.

Encourage others to plant non-invasive plants and to replace existing invasive plants.

Use mulches and/or ground covers in open garden areas to prevent invasives plants from establishing

Report the location of invasive plants to your local weed inspector or by-law officer (in Calgary phone 311)

Why eliminate invasive plants from your garden

Some plants from other parts of the globe, originally introduced as garden flowers, for landscapes, or for their medicinal or food value, have jumped the garden fence to become invasive in the natural environment.  Invasive plants are spread, intentionally and unintentionally, by people and their activities.  They have no natural predators to stop their spread so they survive, thrive, and dominate, in the wild.  Accidental or intentional, these invaders cause not only environmental and habitat degradation, but social and economic loss as well.  Their growth and rapid spread is detrimental to native plants and damages natural areas, rangelands, parks, watersheds and lakes.  They threaten the biodiversity of our native habitat and endanger wildlife. While only about 10% of introduced ornamental plants actually become invasive, effective action needs to be taken to avoid planting the ones that do.  Choosing suitable alternatives can help prevent future spread and serve to protect and preserve Alberta’s natural environment.


Against the Law

It is against the law to grow any of the invasive plants featured.  The Alberta Weed Control Act was put in place to protect Alberta.  Fact sheets on all Alberta-regulated plants, both Noxious and Prohibited Noxious, can be found on this website under the FACT SHEETS tab on the menu bar.


For the avid gardener check out the Alberta Gardener magazine.  Lots of great information on gardening.
