I saw the first pic and thought boneset- I've looking at this blooming near our hives in the country- also in the same field is what looks like smartweed. I've never noticed either before keeping bees.
What a difference a monitor makes - first pic is NOT butterfly bush, and I don't know what the 2nd one is. I just moved to the country 10 years ago, so if it isn't a city weed I'm still figuring out what it is. Speaking of which, can anyone id this? Hoping the bees will work it, it seems to have green blooms
