Species:canadensis

Family:Ranunculaceae

Hydrastis canadensis, commonly known as golden seal, is a perennial herb characterized by a robust rhizome that contains yellowish sap. This plant features two leaves positioned near the top of a straight stalk, which are divided into three to seven lobes. Its solitary flower comprises numerous greenish-yellow to greenish-white stamens and pistils, but lacks petals. The fruit, which is not edible, resembles a crimson berry.

Golden seal is cultivated on a limited scale in mountainous regions for its medicinal properties, particularly the rootstock, which is utilized as a digestive aid, insect repellent, and natural yellow dye. In North Carolina, it has been classified as endangered or of special concern.

In terms of habitat, golden seal thrives in mesic forests that are rich in nutrients, typically found in soils that are circumneutral and situated over calcareous or mafic rocks like limestone, amphibolite, and dolostone. Following disturbances in the canopy, such as logging, this plant can sometimes establish large colonies.
