Costus speciosus is the tallest species of Costus attaining a height of 10-12′. In South Florida this plant goes dormant dying back to the rhizome. In the summer months it has large papery white flowers protruding from a cone like structure. There is also a pink flowering variety that doesn’t get quite as tall. Young canes tend to spiral as with other species of Costus. This plant can grow in partial shade or full sun and does best when kept moist.
Richard Lyons Nursery currently has the white and pink varieties in stock.
