Cyperus distans

Cyperus distans, also known as slender cyperus, is a species of sedge native to tropical and subtropical wetlands in sub-Saharan Africa, Asia (India, Indochina, China, Indonesia, Philippines, etc.), Madagascar, New Guinea, Australia, Latin America (from Mexico to Argentina), the West Indies, the southeastern United States (Florida, Georgia, North Carolina) and various oceanic islands.

Description

A sedge. It keeps growing from year to year. It grows 30-100 cm high. It forms a loose tuft. The stalks have 3 angles and are thickened near the base. There are small corm-like underground stems or rhizomes. The blades are narrow and 4-6 mm wide. They are weakly folded The sheaths are light brown. The flowers are in groups at the one level and there are leafy bracts.

Edible Uses

Tuber - raw or cooked. Used in sauces. The rhizome is used in food as a condiment and a spice. The plant ashes are extracted for salt. No further details are given, but the general process is to burn the dried plant then percolate water through the ashes to dissolve out the salts. The water is then evaporated to leave behind the salts. We have no specific information for this species, but it is said that the inner base of the young stems of all species in this genus can be eaten raw, and make an excellent survival food in times of need.

Traditional Uses

The rhizome is used in a sauce.

Cultivation

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it is unlikely to succeed outdoors in any but the very mildest areas of this country. The following notes are based on the general needs of the genus. Prefers a moist sandy loam.

Propagation

Surface sow seed in spring and keep the compost moist; germination usually takes 2–6 weeks at 18°C. Prick seedlings into individual pots as soon as large enough to handle, grow through their first winter in a greenhouse, and plant out in late spring after the last expected frosts. Division in spring or autumn essentially involves harvesting tubers and replanting them; tubers lifted in autumn are best stored in a cool, frost-free place over winter and planted out in spring.

Other Uses

The leaves are used for weaving hats, matting, and similar items.

Notes

There are 550 Cyperus species.
