This was confirmed by Heather Irvine (our guide and a former student at the Northeast School of Botanical Medicine in Ithaca, NY and current student at the Vermont Center for Integrative Herbalism) on a Wild Edibles Walk at the North Branch Nature Center in Montpelier when it was pointed out to us. This plant is not featured in either of my wildflower books (Wildflowers of Vermont and National Audubon Society Field Guide to Wildflowers Eastern Region). For more information go here and here.
