American white hellebore

American white hellebore, also known as American hellebore or itchweed, is a poisonous herbaceous plant belonging to the genus Veratrum. This genus, part of the Melanthiaceae family, comprises approximately 25 to 30 perennial species native to damp areas across the Northern Hemisphere.12

American white hellebore is characterized by simple, parallel-veined leaves and terminal clusters of small flowers, which can range in color from greenish-white to brownish-purple. While some hellebore species are cultivated as garden ornamentals, the poisons derived from Veratrum have found applications as insecticides and in medicine. The plant was first documented in 1816.123
