Dominant Weeds in 2009

Everybody knows weeds since we all curse/hate/want to mangle them. But have you noticed some that have done exceptionally well this year? Here at the Extension office, I have noticed 2 that have really gotten my attention.

Virginia Copperleaf

My Weeds of the Northeast book lists this weed as a summer annual, reproducing via seed each spring. It says it can tolerate all moisture conditions. But as anyone living here knows, it's been a rainy year. This weed has always been at the office, but it's population has seemed to skyrocket and the dang things are BIG.

Virginia Buttonweed -- I see a pattern here....

The book says this is a perennial with thick stems growing prostrate. It can root at the nodes (like large crabgrass or bermudagrass). And get this -- this thing is supposed to produce flowers UNDERground!!! My reference says 'little is known about the belowground flowers'. And it seems this one does prefer moist areas. I don't remember seeing any of this last year, but it's come and decided it likes it here.

Weeds are definitely over-the-top this year.
