Edible Uses

Edible Parts: Leaves  Pollen  Root  Seed  Shoots
Edible Uses:

Root - raw or cooked[159, 161, 172, 183]. Rich in starch. The bruised young roots, when boiled in water, furnish a sweet syrup[183]. The rhizomes are 3 - 10mm in diameter[270]. Young shoots - cooked[55, 62, 85, 183]. The tender base of the stem is eaten raw in salads[183]. The pollen is used in soups or mixed with flour and used in making bread[177, 183]. It is rich in protein. Seed[62, 85, 159, 183]. No further details are given but it is probably ground into a powder and used in making bread etc. Small and rather fiddly to harvest and utilize.

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses

Basketry  Weaving

The stems are used in weaving and basket making[189, 257]. They are used to make good quality mats for use on the floor, for sleeping on and for making temporary partitions[257]. The stems are pulled off the plant rather than cut to ensure the maximum length of stem[257].

Cultivation details

We have very little information on this species and do not know if it will be hardy in Britain. However, judging by its native range, it is likely to succeed outdoors at least in the milder areas of the country. The following notes are based on the general needs of the genus. This species may be no more than a synonym for Schoenoplectus tabernaemontani[270]. Succeeds in any wet to moisture retentive ground, pond margins and shallow water in full sun or shade[200].

Plant Propagation

Seed - sow in a cold frame as soon as it is ripe in a pot standing in 3cm of water. Only just cover the seed with soil[200]. The seed usually germinates fairly quickly. Prick out the plants when large enough to handle and plant out in their permanent positions in early summer. Division in spring. Very easy, larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
