Mandrakes are a fictional creature from the Harry Potter Universe.
Mandrakes are living plants that first appear in the Chamber of Secrets. They babies when the 2nd years first repot them in their Herbology class. Adult Mandrakes screams are deadly to anyone who hears them, but the babies just knock you out if you hear them. Nonetheless, the 2nd years still have to wear earmuffs. After the people start to get petrifed, Sprout starts to grow the Mandrakes so that they can be made into a potion that cures the petrification.
