Happy Independence Day to the Bleeding Heartland community! Enjoy the day safely, and please remember that amateur fireworks can not only hurt people, but also cause distress for war veterans suffering from PTSD.

It’s less hot today than usual on July 4, which will make walking with Jennifer Konfrst and other Democrats in this afternoon’s Windsor Heights parade much more pleasant. If you went to any parades this weekend, please share your anecdotes. I urge Democrats to wear sunscreen, comfortable shoes, and a t-shirt with a positive message. Don’t be rude to any political adversaries, and don’t respond in kind if heckled by Republicans. My go-to answers to parade watchers insulting me or candidates I support include, “My dad was a Republican” or “It’s a free country” or “Happy Fourth of July!”

This is an open thread: all topics welcome. Thanks to media coverage picking up on the Iowa DNR’s recent warning about wild parsnip, last year’s post about that hazardous plant and poison hemlock has become the most-viewed edition of Iowa wildflower Wednesday. This weekend’s follow-up with more pictures of wild parsnip has become the most-shared Bleeding Heartland piece about wildflowers, which is ironic, since very few of more than 125 posts in this series have featured European invaders.

Some people confuse wild parsnip with golden Alexanders, a North American native with small yellow flowers. But the plants look quite different, and golden Alexanders tend to boom earlier in the year than wild parsnip.
