Luna Moth Ginger. This is probably the most fragrant of the gingers with the most aromatic "gardenia-like" scent that one can imagine. Hedychiums make a dramatic foliage statement before the flowers emerge in late summer and fall. We have a customer at the Tennessee Aquarium in Chattanooga, TN, which has had great success there growing this selection in the landscape. I was surprised! They love heat. Grow in full sun to part shade for the best flower production.
