The Ontario Invasive Plant Council is already counting down to the May long weekend.
The council is launching a 24 day campaign this week to raise awareness of the types of invasive plants we're introducing into our environment.
Rachel Gagnon says the plants might look nice, but they are potentially harmful.
Gagnon says purple loosestrife is the most famous invasive plant, but says there are numerous others plants people don't realize aren't native to Ontario.
