Invaders in your Garden

“Invasive” is a word used to describe any plant or animal that is growing or multiplying to the point of driving out other species. It’s out of control. It’s not in balance with the rest of the plants and creatures in its ecosystem. An invasive species can be native, but it’s most often non-native. But just because a plant is not native, doesn’t mean it’s invasive. Most of the horticultural varieties in our gardens are non-native, but they behave themselves and don’t spread all over your yard. They are not invasive.

However, there are some very invasive species in Old Ottawa South, and you should know about them.
