About
Veratrum viride, known as Indian poke, corn-lily, 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, devil's bite, duck retten, itchweed, poor Annie, blue hellebore and tickleweed.
Where it grows
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).
