The Gingerbell Blossom Festival existed as a celebration on Alderaan, specifically honoring the gingerbell plant.
As a child, Princess Leia Organa found herself barred from attending the festival one year by her father, Bail Prestor Organa. This prohibition arose after she was discovered surreptitiously observing a gathering within the Grand Ballroom of the Aldera Royal Palace. Her punishment, which prevented her attendance, was a direct result of her placing a wooly moth inside the Minister of Agriculture's desk.
