As gardeners, we bear a heavy responsibility for the plague of exotic species that is spreading over our landscape, displacing native plants and disrupting ecosystems. Our desire for the new, the unusual, the eye-popping has fuelled a massive importation of species from far-flung locations. Unwittingly, we have set the stage for ecological disaster.  But we can step back from the brink. And fortunately, gardeners are beginning to understand that their work is far more than decoration, and the question to ask when buying a plant is not, What does it look like? but What role does it play? and most important, Where does it come from? 

This section will offer resources and information on invasive exotic species.
