Lily

The lily is a type of plant that grows from bulbs and sprouts large flowers. According to Rubeus Hagrid, ghosts tend to generally like lilies, which led to them being used during funerals. Minerva McGonagall also had a fondness for the flower, and kept one in a vase in her office. Hagrid refused to grow them in his garden, as they attracted large slugs.

When Lily Evans first presented Horace Slughorn with the fish Francis, she Transfigured her into a lily petal, set the petal to float inside a bowl filled with very little water in it, and left the presentation for Slughorn to find.

Behind the scenes

 * In the Game Boy Colour version of Harry Potter and the Chamber of Secrets (video game), Harry Potter stole the lily from McGonagall's desk to give to Moaning Myrtle as an act of kindness so she would talk to him about the night Mrs. Norris was petrified. In the book and film, she did so without needing such an act, albeit reluctantly.
