It requires moist or wet soil and can grow in water.




Habitats


Pond; Bog Garden;

Edible Uses


Edible Parts: Leaves; Pollen; Root; Seed; Stem.


Root - raw or cooked[2, 85, 95, 183]. Rich in starch, it can be dried
and ground into a powder or made into a syrup[13, 85, 95, 183]. The
buds at the end of the rhizomes are crisp and sweet, making excellent
eating raw[183].
Young shoots - raw or cooked[85, 183]. Used in spring.
Seed - ground up into a powder and mixed with flour for use in making
cakes etc[85, 183]. The seed is small and rather fiddly to harvest and
utilize.
Base of mature stems - raw or cooked. Somewhat tough[85].
Pollen - raw or cooked. Rich in pollen, it is mixed with flour and used
in making cakes etc[85, 183].



Other Uses


Paper; Thatching; Weaving.


The stems are frequently used for making matting, chair bottoms etc and
thatching[1, 4, 23, 85, 100, 115]. They were at one time imported in
large quantities for this purpose[4].
The pith of the stems is used in paper making[100].


Cultivation details



Succeeds in any wet to moisture retentive soil, pond margins and
shallow water in full sun or shade[1, 200]. Plants can succeed in
fairly deep water.
Hardy to about -25°c[187].
Some named forms have been selected for their ornamental value[187].


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.


Cultivars


There are some named forms for this species, but these have
been developed for their ornamental value and not for their other uses.
Unless you particularly require the special characteristics of any of
these cultivars, we would generally recommend that you grow the natural
species for its useful properties. We have, therefore, not listed the
cultivars in this database[K].
