One of the most fragrant Yellow 'Doctor Moy' Ginger Lilies blooms late in the Fall and has bloomed as late as January in South Georgia during warm winters. The 'Doctor Moy' Ginger Lily is often called the Giant Yellow Butterfly Ginger. The fragrance of the Yellow Butterfly 'Dr. Moy' Ginger flower and foliage is more intense than most Ginger lilies. Many species of butterflies swarm on the Yellow 'Doctor Moy' Ginger flowers to gather the nectar.
