"I was lookin' fer a Flesh-Eatin' Slug Repellent...."They're ruinin' the school cabbages.
-- Hagrid's reason for being in Knockturn Alley (CS4)
A mundane edible vegetable.
- Hagrid maintains a cabbage patch for Hogwarts, presumably to supply the school kitchens. According to Hagrid, flesh-eating slugs have been known to get into them (CS4).
- Strangely, the taste of Polyjuice Potion reminded Harry of "overcooked cabbage," but perhaps that was just the essence of Goyle (CS12).
