Spiral Gingers take their names from their spiral arranged leaves. There are a number of species native from tropical America, Africa, and Australia. They are fairly different from other gingers, and many botanists give them their own family (Costaceae).

Cultural Practices:
Spirals Gingers are not adapted to Phoenix weather, winter is difficult since they don't tolerate long periods of weather below 68° F (20° C). Keep them inside in winter. They also need more humidity than the average garden in Phoenix provides. Use regular application of palm fertilizer, and use mulch.

Blooming Habits:
The Costus barbatus is a very popular cut flower. The blossom can last as long as a month on the plant.
