Beetroot

A beetroot (called a beet in North America) was the edible taproot of the plant Beta vulgaris. Cultivated by humans as a vegetable, beetroot was noted for its intense red flesh, which was sometimes used to make food colouring.

On 23 June 1991, when Harry Potter innocently mentioned that he had a dream involving a flying motorbike that morning, his uncle Vernon Dursley became enraged,  making his face look like a "gigantic beetroot with a moustache."

In his book Marauding with Monsters, Gilderoy Lockhart claimed that he once helped some fans in Essex rid their yard of Horklumps, and in return was offered several bottles of their home-brewed Celery and Beetroot Wine, which he declined.
