As a MG volunteer in my county, I often come in contact with novice, homeowner gardeners who are concerned about invasive plant species but are confused by commonly available literature. This might even describe some more advanced gardeners. Well, I have stumbled upon a very informative website which is dedicated to identifying and discussing invasive species of all types. Put this one in your “reference materials” folder. Lots of photos also.
