The plant in the photo looks to me more like Verbena urticifolia to me because the hairs are not hypodermic. Here is a photo I took of the stinging hairs on the stem of Urtica gracilis (with short non-stinging hairs) later in the summer, when the plant puts out fewer of them on its main stem.

A long-beaked sedge clump burned yesterday over here, probably for the first time. It had mounded up rhizomes, but they looked like they didn't get cooked.

Yes, I'm very pleased with their work. We are looking forward to burns in the volunteer stewardship area around the Wildflower Garden. The white oak leaves finally started seriously dropping after the hard frosts a few days ago. Here are some pictures of the 36th Street Savanna from this morning.

I was really excited to discover a population in Minneapolis last week. The leaves are so pretty.
