Propagation
Division of established clumps by cutting down foliage to about half its height then cutting into preferably large clumps. They may be slow to re-establish and use only minimal water. 

Sow fresh seeds in late spring and the flowers need to be hand pollinated to produce seeds and it takes up to 7 years to produce flowers from seed.

Botanic information
Leaf: The long (spear-like) petiole stands erect in a large clump up to 2m (6ft) in height. They are terete and open at the top to reveal a small reduced linear grey-green leaf blade that is up to 30 mm (1⅛ in) wide.

Flower: The bisexual tubulate flowers have 3-bright orange sepals and 3-violet blue petals with 2-united and have 5-stamens and a style in the centre. The flower head is held above the foliage on a scape up to 1,200mm (40in) long and the flowers unfold from a spathe and have sepals that enclose the petals and appear from winter to spring. 

Fruit: The fruit is a 3-celled wooded capsule. small seeds are viable but the plant is commonly reproduced vegetatively to maintain true to type.
