Mandrake

A Mandrake, also known as Mandragora, is a plant which has a root that looks faintly humanoid. The root of the Mandrake is often used in alchemy, although through means as-yet unknown, upon plucking the roots will sometimes appear to not only be animate, but sentient as well - often screaming as soon as the root touches daylight. For this reason, most Mandrake harvesting must take place at night.
