Costaceae are the only gingers that can be propagated by stem cuttings. Propagation: Pieces of the rhizome, division of the clumps, or stem cuttings. This is the most cold-hardy of the spiral gingers, and has been tested and proven root hardy down to 0☏ (-17.8☌).

Moisture: Requires regular moisture but not standing water. Light: Prefers part sun but will grow in full sun if it gets plenty of moisture. A single rhizome will produce new shoots and increase to a 3 ft wide clump in the second year under ideal growing conditions. Crepe ginger grows from thick fleshy roots called 'rhizomes'. Monthly applications of a balanced fertilizer during the summer growing season will benefit this plant. For best results, this plant should get from 3 to 5 hours of direct sunlight daily, and be grown in fertile, organic, moist but well-drained soil. They have red and pink shades of bracts that might look like the bloom, but the inconspicuous white flowers on the top are the actual flower of the plant. The flowers look like crepe paper - thus the common name of crepe ginger. Sometimes Costus are still listed with other gingers in family Zingiberaceae, but generally they are accepted classified in a separate plant family, Costaceae, along with Dimerocostus, Monocostus and Tapeinochilos.
