The name refers to the colorful raspberry colored stem, but that's not the only colorful thing about this Spiraling Ginger. The leaves are dark green, long and glossy with velvety deep purple undersides. The inflorescence is a vivid red with tight bracts and bold yellow flowers. The butterflies love to drink the nectar from the flowers. This is a large vigorous ginger, growing up to 5-6 ft tall.
