Sorry, pic is fuzzy. Buds seemed to be pink.

It's Philidelphia Fleabane I believe, but I cant verify whether or not the stem leaves are clasping the stem, because of the angle of the shot. It's always helpful to show how the leaves are attached to the stem. They should be clasping the stem. Erigeron philidelphicus often has pink flowers. Philidelphia Fleabane is the most garden or prairie worthy of all the eastern Erigeron species after Robin's Plantain, Erigeron pulchellus. I like philidelphicus better than Daisy Fleabane, Erigeron annuus. I usually keep a few philidelphicus vollunteers if they aren't a threat to my other plants, but I have a tiny garden, so I have to keep them under control. I deadhead them before the seeds ripen, but there are still vollunteers that land in my beds.
