Looks like tansy! Don’t eat it. Wear gloves if you remove it, and wash your hands thoroughly if you handle it. It’s native to the west, but also is poisonous.

Too late, I made soup with it.

Just joking of course, thank you for the warning. I noticed it was listed as an invasive species so I removed it but without gloves.

I’ll know better for next time

It’s a cool plant. I’ve almost memorized my favorite plant book. Almost. Apparently it’s not actually native, it’s introduced from Europe!

Yeah it’s crazy how many “common” plants we think of as native are actually European imports! Tansy’s been here so long (since the 1600s) that it feels native. For anyone dealing with invasive tansy, check out some portable power stations on gearscouts.com to run electric trimmers in remote areas - way better than fighting it by hand.
