Costus spicatus, or Indian Head Ginger, is a herbaceous tropical perennial plant that grows from rhizomes. It is one of the easiest of the ornamental gingers to grow. It has tropical looking foliage with leaves that spiral around the main stem. It also has bright red cone shaped bracts, with orange and yellow flowers that emerge one at a time. The flower bract is long lasting and makes an excellent cut flower. It will flower in spring and summer, or year round in tropical conditions. The plant does best in tropical to sub tropical zones, but can also be grown in colder areas that experience frost. It may die down in colder months, but will reshoot again when warmer weather comes. It is a vigorous grower that can quickly make a large clump. It can be grown as a container plant, in large containers.
Costus like a well drained fertile soil. They like a part shaded position, regular fertilising and watering. They can take a sunnier position if kept well watered. They have few pests and diseases.
Propagation is from division of the clump, or by stem cuttings.
Costus spicatus is also known as Costus scaber and Alpinia spicata.
