Propagation
Sow fresh seeds as viability is short in a well-drained moist media and place in a warm humid environment. Prick out and pot up when large enough to handle. The seedlings may be variable.

Division of offsets during spring.

Botanic information
Leaf: The soft leathery textured mid to bluish green lanceolate to oblong leaves are up to 700 mm (28 in) long by 140 mm (5½ in) wide and have an acuminate apex. The bases are overlapping and sheaved to the other leaves forming a tube and are upright at first and droop with age. The waxy upper surface is concave and the underside has a purplish tinge.

Flower: The creamy-white funnelform flowers are up to 80 mm (3⅛ in) long and wide with green sepals and 3-recurved linear petals. They have 6-exserted curved stamens and a protruding style. They are arranged in a large upright branched panicle that is up to 5 m (16 ft) tall. They appear during late spring or sporadically throughout the year in tropical regions.

Fruit: The small capsule contains numerous seeds with basal tufts of long straight hairs. There are between 80,000 to 200,000 seeds produced on a single inflorescence and are viable but the plant is commonly reproduced vegetatively to maintain true to type.
