Q.  What is the difference between aggressive and invasive plants?

A.  The 51�Թ� defines an invasive plant as “a species, usually nonnative, that is able to establish itself within existing native plant communities and is posing a threat to the integrity of the community.”

An aggressive plant is one that spreads faster than preferred, or into an area of your garden where it is unwanted. A plant may be aggressive in one area of a garden or neighborhood and well behaved in another.
