Propagation
Sow fresh seed during spring and maintain a temperature of 19º to 27º C. (66º to 81º F).
Division of the rhizome, including a growing tip during spring.

Botanic information
Leaf: The dark green oblong leaves are up to 150mm (6in) wide with a leathery texture and stand erect forming pseudo stems with the sheaved leaf bases.

Flower: The tubulate flowers are arranged in a terminal zigzag spike on a peduncle that is up to 300mm (1ft) long and consist of 3 to 6- sharply ascending narrow tapering bracts that are orange-green, pink or yellow. 

The flowers have yellow-orange tepals, tipped in dark green. The flowering period is during spring but can vary in tropical regions and they may appear throughout the year.

Fruit: The globular berry-like capsule contains 1 to 3 seeds that are viable but the plant is commonly reproduced vegetatively.

Culture
All plants in this genus require abundant moisture during the growing season and rich humus rich soil. They tolerate some cooler weather but prefer a hot humid environment. 

It the soil becomes frozen the plant dies off but if it is not too severe the rhizome will re-shoot. The flowers only appear on 2-year old growth and under cold conditions it may never flower. 
If grown in containers use a peat base sandy mix and use a balanced liquid fertiliser during the growing period and reduce watering during winter.
