I have found yet another useful site in my neverending quest to identify the flora that visits my yard: Weed Science Society of America. Tocqueville was right; Americans will form an association for every conceivable object of interest. The Weed Society has some useful resources for plant identification, but they also wax nerdy, as science folks typically do. Mark your calendars; the W.S.S.A. will conduct its WeedOlympics at the University of Tennessee at the end of the month. The general student body at that state school may expect something rather different, though, when they hear of the event.
“When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.” (I do not know the source of this wisdom, but it is rather true.)
