The Year of the Arrow-Leaved Tearthumb

Polygonum sagittatum

Sometimes we say to each other "Last year, weren't there more New England asters?" or "Isn't it much snowier this year than last?" or "Gosh, I don't remember seeing mosquitoes in February before, maybe it's global warming..."

Just for the records, this was the year in which every modestly wet spot with a dab or two of sun was overrun with... Arrow-Leaved Tearthumb.

Slope (!) near greenhouse, tearthumb higher than blackberry canes

A wave consisting of carpgrass, stiltgrass, and, above them all, tearthumb.
