Gillyweed is a magical plant native to the Mediterranean and resembling a bundle of slimy, grey-green rat tails. When it is eaten by a witch or wizard, one grows gills and webbing between the fingers and toes. There is some debate among Herbologists as to the duration of the effects of Gillyweed on fresh water versus salt water, [1] but the effects of Gillyweed in fresh water seems to last about an hour.

Gillyweed can also, presumably, be used as an ingredient in a drink called Gillywater. Professor McGonagall once ordered a glass of it in The Three Broomsticks. Romilda Vane offered Harry a glass of gillywater spiked with a love potion in an attempt to get Harry to ask her to Professor Slughorn's Christmas Party.

Harry Potter used Gillyweed during the Second Task of the 1994 Triwizard Tournament. Dobby gave it to him, under the direction of Barty Crouch Jr. who was disguised as Professor Moody.
