Aggressive plants
can be more than pretty perennials that have gotten out
of hand in your garden.
As I mentioned in the Garden Thugs article in Garden Gate
issue 69, some can become invasive. They escape from a garden and
spread into the wild. Often they’re so fast spreading and
rampant that they kill native species that get in their way. To
learn more about this serious problem, check out these links.
