No one correctly guessed the most recent plant quiz, Galeopsis tetrahit, common hemp nettle. Below are photos of the plant in flower.
The genus name Galeopsis means "looks like a weasel," which is supposedly a reference to the flowers. I don't see it. This plant was found in Superior, Wisconsin, but as I said earlier, it is non-native and found throughout much of northern North America.
Since no one got this quiz correct, do I post the next one?
