So I'm outside, quietyly picking weeds from my garden. I grab one and it stings me! Expecting to see a bee, I look at my finger and see nothing. I look at the weed and it as little, think white thorny hairs all over it's stem. THAT was the culprit! It managed to sting me no less than 4 more times during the course of my weeding. I think it's a type of broadleaf. I live in zone 6ish (on the border between 6 and 5). What type of weed is this? If you know... I need to know the little bugger next time so I can adequately curse at it besides saying, "YOU! You!"
