Severity scale:

Notoriously poisonous to all species, the species of the deadly Nightshade plant, Atropa, is named after 1 of the 3 fates of Greek mythology.  Oddly enough, the Nightshade is a perennial herb in the tomato family native to Europe, northern Africa and Western Asia.  Nightshade has been used in pharmaceuticals, alternative medicine, recreational use, cosmetics (some cultures use the pupil dilation effects as a beauty regime) and as a poison.  Nightshades are branching plants growing up to 6 1/2 feet tall, and are most noted for their sweet tasting, shiny black poisonous berries.
