Was Persephone the goddess of flowers?
She is the goddess of spring, along with the underworld.
Persephone is indeed the goddess of flowers. She is only the goddess of flowers and the reason is clear- she was kidnapped by Hades, the greek god of the Underworld and forced to be his wife. I feel sorry for Persophone because I wouldn't want a husband known for bringing people to their death to the underworld.
Persephone was the goddess of springtime, and Demeter, the goddess of the harvest's daughter. Persephone is the Goddess of the Underworld and the Goddess of Harvest. She is the Goddess of the Underworld because she was forced to marry Hades, God Of The Underworld, and Goddess of Earth because she is the daughter Of Demeter, Goddess of Bountiful Harvest.
Hades kidnapped Persephone to take her to the Underworld. He wanted her as his wife and Queen. Hades at that time, was in love with Persephone, the daughter of Demeter, the goddess of spring and harvest. Persephone at that time, was dancing and picking flowers, such and such where she was then pulled into the ground, and thus, into Hads or the Underworld.
