Persephone's Flowers are a type of magical flowers grown by the goddess Persephone in her garden in the Underworld. While some of them are just regular flowers, as she is the goddess of springtime and flowers, others can be used for more specific objectives, such as when Percy Jackson, Thalia Grace, and Nico di Angelo were on a quest looking for the Sword of Hades, in which Persephone gives them a tracking flower and a travel rose to help them find the thief.
