White umbellifer plant growing in wetland, possibly Angelica? Not sure.
No interactions present.
The leaves (broadly toothed) and stem (purplish) look right, so do the inflorescences. Photo 3 seems to show the sheaths around the stalks that are typical of Angelica. Looks good to me, but I'm no expert.
