Veratrum californicum ([California] corn lily, white or California false hellebore) is a poisonous plant native to mountain meadows in southwestern North America and the Rocky Mountains. It grows 1 to 2 meters tall, with a stem resembling a cornstalk.[1]

It is a source of jervine and cyclopamine, teratogens which can cause birth defects such as holoprosencephaly and cyclopia in animals that graze upon it. These substances inhibit the hedgehog signaling pathway.[2]
