Description of Plant(s) and
Arum is a perennial plant; its tuberous rootstock is poison when fresh but edible when dried or sufficiently cooked. It is about the size of a walnut and is brown outside, white inside. Arum's arrowhead-shaped leaves are also poisonous when eaten. Its flowers, which bloom in May and June, trap insects which the plant digests for food.

It grows in moist, shady places, along hedges, among bushes, and in deciduous forests.
