No interactions present.
Not that much to go on from the picture. It would be useful to put a picture of the leaves, as well; and fruits, if there are any. Looks possible, but not enough to go on, for me.
Incidentally, you could add the scientific name by editing and pressing 'Get recommended'. That would bring up other pics of the species (if there are any), for comparison.

Thanks - a friend took the picture so I've no more information. The field certainly has numerous previous recordings of Corky-fruited Water Dropwort
