Typha latifolia

Physical Characteristics

Typha latifolia is a PERENNIAL growing to 2.5 m (8ft) by 3 m (9ft) at a fast rate. See above for USDA hardiness. It is hardy to UK zone 3. It is in flower from June to August. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and is pollinated by Wind. It is noted for attracting wildlife. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers wet soil and can grow in water.

Distribution

Edible Uses

Edible Parts: Flowers Leaves Oil Pollen Root Seed Shoots Stem Edible Uses: Oil Roots - raw or cooked[2, 12]. They can be boiled and eaten like potatoes or macerated and then boiled to yield a sweet syrup. The roots can also be dried and ground into a powder, this powder is rich in protein and can be mixed with wheat flour and then used for making bread, biscuits, muffins etc[55, 62, 95, 183]. One hectare of this plant can produce 8 tonnes of flour from the rootstock[85]. The plant is best harvested from late autumn to early spring since it is richest in starch at this time[9]. The root contains about 80% carbohydrate (30 - 46% starch) and 6 - 8% protein[85]. Young shoots in spring - raw or cooked[12, 55, 62, 94, 102, 183]. An asparagus substitute. They taste like cucumber[212]. The shoots can still be used when they are up to 50cm long[85]. Base of mature stem - raw or cooked[2, 9, 55]. It is best to remove the outer part of the stem[62, 183]. It is called 'Cossack asparagus'[183]. Immature flowering spike - raw, cooked or made into a soup[62, 85, 94]. It tastes like sweet corn[183]. Seed - raw or cooked[2, 257]. The seed is rather small and fiddly to utilize, but has a pleasant nutty taste when roasted[12]. The seed can be ground into a flour and used in making cakes etc[257]. An edible oil is obtained from the seed[55, 85]. Due to the small size of the seed this is probably not a very worthwhile crop[K]. Pollen - raw or cooked. The pollen can be used as a protein rich additive to flour when making bread, porridge etc[12, 55, 62, 94, 102]. It can also be eaten with the young flowers[85], which makes it considerably easier to utilize. The pollen can be harvested by placing the flowering stem over a wide but shallow container and then gently tapping the stem and brushing the pollen off with a fine brush[9]. This will help to pollinate the plant and thereby ensure that both pollen and seeds can be harvested[K].

Medicinal Uses

Anticoagulant Astringent Diuretic Emmenagogue Galactogogue Haemostatic Miscellany Refrigerant Sedative Tonic Vulnerary The leaves are diuretic[218]. The leaves have been mixed with oil and used as a poultice on sores[257]. The pollen is astringent, diuretic, emmenagogue, haemostatic, refrigerant, sedative, suppurative and vulnerary[218]. The dried pollen is said to be anticoagulant, but when roasted with charcoal it becomes haemostatic[238]. It is used internally in the treatment of kidney stones, haemorrhage, painful menstruation, abnormal uterine bleeding, post-partum pains, abscesses and cancer of the lymphatic system[222, 238]. It should not be prescribed for pregnant women[238]. Externally, it is used in the treatment of tapeworms, diarrhoea and injuries[238]. A decoction of the stems has been used in the treatment of whooping cough[257]. The roots are diuretic, galactogogue, refrigerant and tonic[218]. The roots are pounded into a jelly-like consistency and applied as a poultice to wounds, cuts, boils, sores, carbuncles, inflammations, burns and scalds[222, 257]. The flowers are used in the treatment of a wide range of ailments including abdominal pain, amenorrhoea, cystitis, dysuria, metrorrhagia and vaginitis[218]. The young flower heads are eaten as a treatment for diarrhoea[222]. The seed down has been used as a dressing on burns and scalds[257].
