When Flora goes to the Black Mud Swamp to prepare for her exams she tells the Winx that she is looking for the Cheerful Gladiolus to use for her potions but that it is dangerous to pick it as it has many thorns. She then shows them a rapid-growth potion she invented so that she will be able to make a Cheerful Gladiolus grow for her.
