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

Botanic information
Leaf: The leaves are oblong to lanceolate with an acuminate to acute apex. The dark green upper surface has lateral stripes that are reddish when young becoming white and the undersides are purplish. The petiole is terete and is up to 400mm (16in) long.

Flower: The tiny 3-lipped tubulate flowers are arranged in a terminal spike with bracts on a scape that is up to 80mm (3⅛in) long and may be hidden under the foliage. 

The irregular flowers have 3-sepals and a 3-parted tubular corolla that is violet-coloured and the contains a 3-celled inferior ovary.
The flowering period is from late spring to early summer but can vary in tropical regions and they may appear throughout the year.

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 require an average temperature of 10ºC (50ºF) to 15.5ºC (60ºF) avoiding sudden variations in temperature. It 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.
