More roadside flowers

I took a drive around the "block" last night. I always find this road sign amusing..... Sharon is the name of a tiny town nearby, and there is a stone quarry on this road called Sharon Stone.
T Ridge is the inspired name one of our township trustees came up with when our road needed to be named for our new 911 service. Wish they had asked for suggestions - I would have called it Still Hollow, after our 90+ year old twin bachelor neighbors.
I like these "weeds". There is a frittiary butterfly just swooping in from the left upper corner.
Not sure what this is - I'll have to do some research - or do you know?
This is button bush. Its normally found in wet areas, so there must be a spring coming out of the hill above the road.
