Does anyone recognize this? It seems to be very common.
Update, 26 June: Pamela Leo reports that it’s Pennsylvania smartweed.

Is it a kind of pigweed, maybe? Looks amaranthish.
This is a beautiful photo. So graceful. Can't find it in my Texas wildflower books…sorry
It's Pennsylvania Smartweed (polygonium penylvancium).
Some of your other wildflower finds are:
Spiderwort (tradescantia ohiensis)
Common or Daisy Fleabane (most likely erigeron annuus) and
White Snakeroot (eupatrium rugosum)
P.S. Thank you so much for keeping a close eye on the goings on at the NYPL.
