Safety note: All parts are highly toxic; one of the most poisonous plants in western North America.

Corn Lily is a tall, robust wildflower of wet mountain meadows that superficially resembles corn with its large, ribbed leaves. Despite its lush appearance, it is highly toxic to livestock and humans, containing potent alkaloids. Elk avoid it, but deer and many insects can visit the clusters of white flowers. Early shoots can be mistaken for edible plants.
