Propagation
Division of the rhizome, including a growing tip during spring or division of the clump in spring.

Botanic information
Leaf: The leaves are long cordate to oblong with a cordate base and is held erect on a slender petiole up to 1m (3ft) long. The upper surface is dark green with a yellow-green mid rib and pinnate venation. The underside is grey-green and the apex is acuminate.

Flower: The tiny 3-lipped tubulate flowers appear in a spike that has 2-ranked orange-yellow bracts and has a scape that is up to 1m (3ft) tall and grows from the ground. The irregular flower has 3-sepals and a 3-parted tubular corolla with a 3-celled inferior ovary. They appear during early summer.

Fruit: The tiny fruit is a 3-celled capsule and the small seeds are viable but the plant is commonly reproduced vegetatively. The flowering and fruiting period may vary in tropical regions.

Culture
This plant requires an average temperature of 10ºC (50ºF) to 15.5ºC (60ºF) avoiding sudden variations in temperature. They prefer a humid environment and respond to regular misting of the leaves. 

When grown indoor place in a position with bright indirect light as the colours in the leaves fades in direct light. 
Keep the soil moist not wet and use tepid soft water, reducing during the winter period.

If the plant forms brown and dry stunted growth it normally is the result of the air being too dry.
Excessive moist soils will cause rot at the base of the plant.
