Oops, I misread this as the wildflower forum. Didn't there used to be one?

That's tansy, tanacetum vulgare. Not native but not invasive, kind of pretty and the foliage is aromatic when crushed. An old-timely garden herb.

Thank you! They're growing along a natural path and I think they're beautiful. I also posted this on the native plant forum. Didn't mean to double-post but I wasn't sure what was the correct forum.

Not hugely invasive, but around here definitely a thug. Don't plant it near something delicate as it will spread and run roughshod over anything not fairly vigorous.
