Veratrum Album
''Veratrum album'', the false helleborine, white hellebore, European white hellebore, or white veratrum ( syn. ''Veratrum lobelianum'' Bernh.) is a poisonous plant in the family Melanthiaceae. It is native to Europe and parts of western Asia (western Siberia, Turkey, Caucasus). Description ''Veratrum album'' is a tall herbaceous perennial plant with alternate, pleated leaves. The flowers are white, marked with green on the top portion of the stalk. The fruit is a small pod containing winged seeds. The stout, simple stems are tall. The plants have an estimated lifespan of several centuries and often achieve dominance in wild areas as they are unpalatable to grazing herbivores. Uses Extracts from dried rhizomes of ''Veratrum album'' were briefly used as a pesticide against the Colorado potato beetle.

Veratrum Californicum
''Veratrum californicum'' (California corn lily, white or California false hellebore) is an extremely poisonous plant native to western North America, including the Sierra Nevada and Rocky Mountains, as far north as Washington and as far south as Durango; depending on latitude, it grows from near sea level to as high as 11,000 feet. 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. ''Veratrum californicum'' displays mast seeding; populations bloom and seed little in most years, but in occasional years bloom and seed heavily in synchrony. The species us ...
