Veratrum viride, known as Indian poke, Indian hellebore, false hellebore, green false hellebore or giant false-helleborine, is a species of Veratrum native to eastern and western (but not central) North America. It is extremely toxic, and is considered a pest plant by farmers with livestock. The species has acquired a large number of other common names within its native range, including American false hellebore, American white hellebore, bear corn, big hellebore, corn lily, devils bite, duck retten, itch-weed, itchweed, poor Annie, blue hellebore and tickleweed.
V. viride is a herbaceous perennial plant reaching 0.7 to 2 metres (2.3 to 6.6 ft) tall, with a solid green stem. The leaves are spirally arranged, 10 to 35 cm (4 to 14 in) long and 5 to 20 cm (2 to 8 in) broad, elliptic to broad lanceolate ending in a short point, heavily ribbed and hairy on the underside. The flowers are numerous, produced in a large branched inflorescence 30 to 70 cm (1.0 to 2.3 ft) tall; each flower is 5 to 12 mm (0.2 to 0.5 in) long, with six green to yellow-green tepals. The fruit is a capsule 1.5 to 3 cm (0.6 to 1.2 in) long, which splits into three sections at maturity to release the numerous flat 8 to 10 mm (0.3 to 0.4 in) diameter seeds. The plant reproduces through rhizome growth as well as seeds.
There are two recognized varieties of V. viride:
The related western North American Veratrum californicum (white false hellebore, corn lily) can be distinguished from sympatric var. eschscholzianum by its whiter flowers and the erect side branches of the inflorescence.
In eastern North America, var. viride occurs from southwestern Labrador and southern Quebec south to northern Georgia. In the west, var. eschscholzianum occurs from Alaska and Northwest Territory south through Yukon, British Columbia, Alberta, Washington, Idaho, Montana, and Oregon to northwestern California (Del Norte, Siskiyou, Trinity, and Humboldt Counties).
