Other Uses
Paper;  Soil stabilization;  Stuffing;  Thatching;  Weaving.

The leaves are woven to make mats, bags and raincoats[46, 61, 193]. The inflorescences are valued for stuffing pillows and cushions[272]. The stems are used in thatching roofs[46, 61, 178, 272]. A fibre obtained from the leaves is used in making paper[46, 61, 154]. Can be planted on sandy soils to prevent erosion[154, 272]. The plants form impenetrably dense clumps and when planted close together in drifts make an excellent ground cover[200].
Cultivation details                                         
Landscape Uses:Alpine garden, Border, Massing, Rock garden, Specimen. Succeeds in ordinary garden soil in sun or partial shade[162, 187]. This species is only hardy in the southern part of Britain, tolerating temperatures down to about -15°c when dormant[187], though the young growth in spring can be damaged by late frosts. The var. I. cylindrica major. (Nees.)C.E.Hubb. is used medicinally in China[176] and as a wild food in Australia[193]. This species is quite closely related to sugar cane, it has been interbred experimentally with that species in India[193]. Plants grow away vigorously after a fire, often spreading freely to infest the burnt areas[144, 193]. Special Features:Attractive foliage, There are no flowers or blooms.
                                                                                 
Propagation                                         
Seed - surface sow in spring in a greenhouse. The seed germinates quickly, prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer. Division in spring as the plant comes into growth. Division is very easy and can be carried out at almost any time in the year, though winter divisions are best potted up in the greenhouse and planted out in late spring[K].
