Fiber Plants

People have been using plant fibres for thousands of years in order to make clothing, rope, paper etc. Whilst all land plants contain fibres they are

usually too short or too weak to be used for anything other than paper-making, but there are well over 100 species suitable for growing intemperate climates that produce long and relatively strong fibres. These fibres vary greatly in their physical properties and can supply us

with cloths ranging from fine and silky to coarse sackcloth or ropes strong enough to berth large ships. We will describe a few of these fibre

plants in more detail and, will confine the list to the perennial species. However, we must mention Flax (Linum usitatissimum), a well known

fibre (and oil) producing annual which can be grown successfully all over Britain.

We'll start this list with a few native plants. Our common Stinging Nettle (Urtica dioica)

probably deserves an article to itself since it has so many uses. Apart from its wildlife value, it can supply us with food, medicine, liquid fertilizer

and compost material. It also produces a good quality fibre suitable for cloth, indeed it has in the past been cultivated for this purpose. It prefers a

rich soil and is more than capable of fending for itself so doesn't really need to be cultivated. Almost any species of nettle can be utilised for

fibre.

The Hop (Humulus lupulus)

is often cultivated as a herb or a flavouring for beer. Found wild in hedgerows, it responds very well to generous treatment in the garden, looking

especially ornamental in early autumn. Tender young shoots in spring are very nice cooked. The stem fibres are used to produce a coarse cloth.

Those people with more space could grow our native Lime Trees (Tilia cordata, T. x. europaea and T. platyphyllus). The fibre is found in the

inner bark and is best from trunks 6-12 inches in diameter so a 10 year coppice rotation is probably the best way of growing these trees. The fibre

can be used for cloth or ropes. These trees produce the nicest edible leaf that we've as yet found on a tree. Only eat young leaves, which can beproduced from April to October on coppiced plants, they are mucilaginous without any strong flavour. A refreshing herbal tea is made from the

dried flowers, the fresh flowers are a magnet to bees and a mixture of fresh flowers and immature fruits is said to make a delicious chocolate

substitute.

Moving into S Europe, Spanish Broom (Spartium junceum)


3/13

is a medium sized shrub growing in dry situations amongst rocks and shrubs. Easily grown in a sunny position and well-drained soil, this plant

has become naturalized in S Britain. The stem fibres are a hemp substitute being used mainly for coarse fabrics, cordage and paper. The stems are

very pliable and can be used in basketry.

Going much further east we find in China one of the very finest and strongest fibres, Ramie (Boehmeria nivea).


4/13

This member of the nettle family is probably only suitable for the warmer southern part of Britain, it is a herbaceous perennial and requires a

rich well-drained soil. It prefers conditions of high humidity and fairly high rainfall so might need irrigation in dry years. The fibres from this

plant are the longest known in the plant world. Their tensile strength is seven to eight times that of silk or cotton and this is actually improved by

wetting. Cloth made from this fibre is said to be moth-proof, it is also used for making very strong ropes and nets.

The Paper Mulberry (Broussonetya papyrifera) is a small deciduous tree whose range extends from China to the tropical South Sea Islands and

yet it is hardy in Britain if given a warm position and a fairly rich soil. When grown for its fibre it is usually coppiced on an annual basis (though

perhaps less often if grown in our cooler climes). To make cloth from this plant the bark is usually cut into strips about 4 x 12 inches and laid out

flat on a smooth wooden surface. It is then beaten with wooden mallets, the more it is beaten the thinner and finer it becomes. Size can be

increased by overlapping other strips of bark and beating them together. Depending upon the degree of beating the resulting cloth can range froma thick material suitable for sacking to the very finest gossamer thin clothing. This plant also produces a delicious fruit but only a very small

proportion of the structure is actually edible which makes it too fiddly to be very worthwhile.

Moving on to New Zealand in this journey around the globe, New Zealand Flax (Phormium tenax)


5/13

Dwarf

is found growing wild in lowland swamps and on low ground. A member of the Lily family, so completely unrelated to our native flax plants, itis easily grown in most soils and is so tolerant of maritime exposure that it can be grown as a screen and windbreak near the coast. The fibre is

found in the long leaves and it can be used to make fine cloth and ropes. There is some difficulty, however, in preparing these fibres due to the

presence of a gum in the leaves. The residual leaf pulp can be fermented to make alcohol for fuel, a fast brown dye is produced from the flowers,

a strip of leaf can be used as an emergency garden tie and the whole leaf is used in basketry.

Finally to N. America where there are a number of fibre plants. Indian Hemp (Apocynum cannabinum)


6/13

not related to Marijuana - is a herbaceous perennial growing in moist or shady places and is easily cultivated in most soils in sun or shade. The

fibre, obtained from the stems in early to late autumn, is very strong, does not shrink and retains its strength in water. It is used mainly for sails,

twine and garden nets. Two other members of this genus A. androsaemifolium


7/13

and A. venetum

produce a similar though slightly inferior fibre.

Along the Pacific west coast of America grow a number of Iris species (I douglasiana, .


8/13

I. macrosiphon

and I. purdyi)


9/13

whose leaf fibres produce a beautifully strong and pliable rope. Traditionally the N. American Indians would take just one fibre from eachoutside edge of the leaves, though I know of no reason why all the fibres could not be used. The Indians would have needed thousands of plants

by their method in order to produce any quantity of rope. Usually found wild on grassy slopes, these beautiful plants are easily grown, preferring

rich well-drained lime-free soils in sun or semi-shade.

The Milkweeds (Asclepia species) are also very good fibre plants - see our leaflet The Milkweeds.

The Milkweeds

Every so often in our researches we come across a plant with so many uses that we wonder why it has never been commercially exploited. One

such group of plant - all of them ideal for the Permaculturalist - is the Milkweeds (Asclepias species) from North America. The genus Asclepias

contains over a hundred species of mainly perennial herbs growing in temperate and topical regions. We will look at four of these species:-

A. incarnata Swamp MilkweedGrowing to 4ft in swamps, wet thickets and on shores.

10/13

A. speciosa Showy Milkweed

Growing to 2.5ft on prairies in sandy and loamy, usually moist soils.

A. syriaca Common Milkweed

Growing to 3ft in thickets, roadsides, dry fields and waste places.


11/13

A. tuberosa Pleurisy Root

Growing to 2ft in dry, open soils.


12/13

All the above are fairly easy to grow preferring a rich light or peaty soil and a sunny position. A. icarnata is probably the easiest to grow and is

the most adaptable to different soil types. They all succeed in most areas of Britain. The only real problem We have has in growing them is thatyoung plants are very attractive to slugs who will totally decimate them. However, established and strong growing plants seem to be little

affected.

Virtually all parts of these plants are edible when cooked though there are reports that large quantities can cause stomach upsets. The young

shoots, gathered in April-May, can be used as an asparagus substitute whilst the younger parts of old shoots can be cooked like spinach.

Young flower buds have a delicious pea-like flavour as do the very young seed pods (before the seed floss is produced). The flowers are used as

a flavouring and a thickener in soups and were also harvested in the early morning when dew was still on them and then boiled down to make a

sugary syrup. In hot weather the flowers often produce so much nectar that it forms crystalline lumps. This can either be sucked or picked off the

flowers and is a real delicacy. In our experience to date A. tuberosa is the most likely to do this. A. tuberosa, as the name suggests, also produces

a tuberous root and this is edible when cooked, with a nutty flavour. The seed of all species are said to be edible raw but we have not tried them,

they certainly do look very interesting.

All these edible qualities, though, are just one aspect of the plants uses, they have much more to offer. All the species produce a tough fibre intheir stems. This can be used to make cloth, twine, etc and was traditionally harvested from the dead stems in autumn and winter, a fairly simpleprocess. Dry summers produce the strongest fibres.

Mature seed pods contain quite large quantities of floss. This is a lovely white silky material with a number of applications. It can be used as a

kapok substitute for stuffing soft toys etc, and being very water repellant, it has been used in life preservers where its buoyancy can keep a person

afloat for days. Although difficult to spin on its own, it can be mixed with other fibres to make cloth and it has also been used for making candle

wicks.

The plants also contains a latex which can be extracted and made into a good quality rubber. This latex is largely found in the leaves, is produced

mainly in hot weather when grown on drier soils and is destroyed by frost. Concentrations vary and are considered to be too low for commercial

exploitation. The latex has also been used as a chewing gum and regular applications are said to be a cure for warts.


13/13

The seeds contain up to 20% of an edible semi-drying oil. This oil can be used in making soap etc, though, since the seed is quite light, vast

quantities of plants would need to be grown in order to obtain reasonable quantities of oil. The plants also have medicinal applications, for moredetails on these you should consult a good herbal such as 'A modern Herbal' by Mrs M Grieve.

Plants are very easily raised from seed, sown in a cold greenhouse from February to April. Seedlings should be potted up when quite young sincethey resent much root disturbance. Plant them out in their permanent positions in early summer and look out for slugs. If the plants have been

well grown and are in vigorous growth then they are normally alright but any weaker plants are likely to disappear. We have had very little

trouble with older plants. If done with great care, plants can be divided in spring when they come into active growth though We have not done

this myself since seed is so easy.

One final thought - all of the above plant uses come from wild grown plants, there has been no attempt made, for example, to increase the latex

content by selective breeding. We feel that there is vast potential with this group of plants and with many other species for improvements in

yield, flavours, etc.

(You might also like to have a look atMilkweeds and Monarch Caterpillars a site with a lot of info about the plant and about the catapillers

which like them. )

Obtaining the fibres from the plant is usually a fairly straightforward though smelly and labour intensive process. We don't intend to go into any

great details having no experience of the extraction process. The basic principle however is to encourage the softer parts of the plant to rot so that

only the stronger fibres remain. This is usually done by either immersing the plants in water or tying them up in bundles outdoors for the dew and

rain to work on them. Once the softer parts start to rot the fibres are separated and cleaned and are then ready for use. At least it sounds easy,

though we would advise you to read up on the subject before trying it.
