Today I learned that wild parsnips can cause burns on your skin. We'd been picking blackberries for a couple of days, and I wore long sleeves but my shirt would get caught on thorns and ride up sometimes when I was climbing from one place to another. It took some googling to find plants that make the kind of non-itchy marks I had on my torso, but the images of wild parsnip matched the stuff that was mixed in with the brambles. Of course, my kid knew all about it when I mentioned it, but I didn't think to ask her first.
She wants to cook and eat the roots, but I think I'm going to just put on some gloves and do my best to remove them from the walking path.
I also learned that if you keep millipedes and dirt in a gallon tapjar, you have probably ended that jar's life as a tea dispenser.
