Hydrophyllum virginianum — eastern waterleaf

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Eastern waterleaf is found in moist, often rich deciduous and riparian forests in Connecticut, Massachusetts, New Hampshire and Vermont. The leaves often have white mottling, which gives them a water-stained look, hence the common name. The Iroquois and Menominee ate the young plants and leaves after cooking.
