In Disney's 1991 animated Beauty and the Beast, the enchantress leaves an enchanted rose as a warning. Its falling petals mark the limited time the prince has to break the curse.
The rose is kept beneath a glass cover in the castle. The enchantress warns that the prince must learn to love and earn love in return before the rose's last petal falls. If he fails, he and the castle's servants will remain transformed permanently.
The rose is not the gift Belle receives from the Beast; that separate moment involves a library. The flower functions as a visual clock throughout the story, making the approaching deadline clear without repeated explanation. Its final petal falls during the Beast's battle with Gaston, just before Belle declares her love.
