Other Uses
Basketry Fibre Weaving
A watertight basket can be made from the leaves[21, 46, 61, 99, 257]. This basket has been used for cooking food in[257]. The fibres are split from the leaves and then used[92]. The plant is also used to decorate baskets[257]. The small leaves have been used to make dresses[257]. The plants were burnt every year. The leaves were harvested in the spring when they first started to grow out of the charred rhizome. Prior to using, the leaves were soaked in water to make them pliable, but if left too long they turned green[257]. The dried and bleached leaves are used for weaving into hats and capes[207, 257].

Cultivation details
Requires a well-drained soil in full sun[187]. Prefers a fairly moisture-retentive sandy peaty soil[1, 200]. Requires a damp peaty soil[233]. Plants can be difficult to cultivate[188]. Plants are hardy to about -20°c[187], especially if the roots are given a good mulch in the winter[200]. If left undisturbed, plants can form quite large colonies, spreading by means of their tough rhizomes[200]. Plants do not flower every year, there are often gaps of 5 - 7 years between flowering[212].

Plant Propagation
Seed - we have no information for this species but suggest sowing the seed in a cold frame as soon as it is ripe if possible, otherwise in early spring. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division as the plant comes into growth in the spring.
