Veratrum californicum (California False Hellebore; corn lily)

Wikipedia Abstract

Veratrum californicum (California corn lily, white or California false hellebore) is a poisonous plant native to mountain meadows at 3500 to 11,000 ft elevation in southwestern North America, the Sierra Nevada and Rocky Mountains, and as far north as Washington State and as far south as Durango. It grows 1 to 2 meters tall, with an erect, unbranched, heavily leafy stem resembling a cornstalk. It prefers quite moist soil, and can cover large areas in dense stands near streams or in wet meadows. Many inch-wide flowers cluster along the often-branched top of the stout stem; they have 6 white tepals, a green center, 6 stamens, and a 3-branched pistil (see image below). The buds are tight green spheres. The heavily veined, bright green leaves can be more than a foot long.
