Invasive Plants

Invasive plants do untold damage to Ontario’s natural areas, displacing native plants and damaging habitat. These invaders do untold damage and the cost of removal is high . Many nurseries still sell invasive plants exacerbating the spread. The above list from Credit Valley Conservation Authority has been approved by the Ontario government. If you have plants in your garden that are listed under Category 1, Transformers, or Category 2, Highly Invasive, should be removed immediately.  cvc-appendix-guide-to-invasives

The Ontario Invasive Plant Council has an excellent booklet, Grow Me Instead, which can help gardeners find alternatives to invasive plants.   Southern-Grow-Me-Instead 

Keystone Species

Keystone plants are native plants critical to the food web and necessary for many wildlife species to complete their life cycle. Without keystone plants in the landscape, butterflies, native bees and birds will not thrive. 95% of our terrestrial bids rely on insects supported by keystone plants.”  National Wildlife Federation

In the native plant community 5% of native plants support 75% of our native insects and birds. They include our native oaks, cherries and willows.  Among perennial species, goldenrod, aster and rudbeckia are keystone species.

Recommended Reading

Doug Tallamy, an entomologist and educator, has several excellent books on the importance of native plants.  His recent book, Nature’s Best Hope, is a recommended read.  Tallamy outlines how native plants support our local ecosystems and how our home gardens are important to preserving native species.

Lorraine Johnson’s book, 100 Easy to Grow Native Plants is a great resource to help plan your garden. It contains excellent photos and descriptions of native plants.

Pollinator Gardens

Check out our attached lists of the best plants for pollinator gardens, including an excellent list from Credit Valley Conservation and a list from the Xerces Society.

As well as providing nectar, a pollinator garden should include host plants for the caterpillars of butterfly and moth species, as well as pollen for our specialist bees.
