Propagation
Division of the rhizome during spring is the normal method of propagation. Plant the shoot buds upwards at a depth of 40mm (1⅝ in) in a pot and place it in a warm semi-shaded position and apply slow release fertilise and keep moist. Plant out when established.

Sow fresh seeds in containers during spring.

Note:
Torch Ginger is one of the tallest species in the genius and the flower buds are edible and a commonly used in Southeast Asia cooking.

Botanic information
Leaf: The glossy dark green linear to lanceolate leaves are up to 1 m (3 ft)  long with entire-undulating margins and an accumulate apex. The petiole is short and the underside is purplish-green with a prominent mid-rib. They are arranged alternately on a single plane along the unbranched psudostems.

Flower: The small red labiate flowers have 3-corolla lobes with a lip-petal that has a yellow or white margin. They are arranged in a terminal cylindrical spike up to 180mm (7 in) wide and 150 mm (6 in) long (pine cone shape) with large basal waxy red to pink bracts with white margins and the flowers appear amongst the smaller crimson bracts. The inflorescence appears on a leafless scape from the rhizome during early summer.

Note
The flowering period can vary in tropical regions and the flowers may appear throughout the year.

Fruit: The small capsule contains tiny seeds that are viable but the plant is commonly reproduced vegetatively.
