Yesterday's Wildflower

Daisy Fleabane, Erigeron annuus, Brooklyn.

It likes fields, roadsides and waste places and apparently so must I, because I keep seeing it. I've seen it described as a native weed, which may or may not be an oxymoron. Now I hope I have the species of Erigeron right, because it seems like there are many, but I've been trying to distinguish this species based on the fact that it doesn't have clasping leaves like some others and seems to be flowering at the right time. According to Brooklyn Botanic's New York Metropolitan Flora project, I see at least four species listed in the genus for the area, so it's not like I can be certain. The funny thing is that when I saw the plant, I thought I knew what I was seeing and yet again, I was on the hunt.
