Costus speciosa is a tall spiral type ginger with large 4" white crepe type flowers that emerge from the central cone. A tough fairly hardy ginger at the root level and easy to grow with attractive tropical leaves. New shoots emerge from the root stock at regular intervals and in the tropics it would create a 3ft wide 8ft tall clump in a year! Grows to around 6ft here in pots and should take -10C when mature at root level.
