Cultivation:
Succeeds in subtropical and tropical climates at low to moderate elevations. It is found in areas with an annual rainfall of 1,000 – 1,600 mm.
The plant grows best in a well-drained soil with a high organic matter content. Prefers sandy loams. The plant requires support and shade and is often grown among cocoa trees.Removal of the flowering shoots encourages leaf production. In northern Sierra Leone two varieties are recognized and the leaves of both are eaten.

Propagation: Threough Seed – Stem cuttings 20 – 25 cm long, obtained from mature shoots. The plant is described as being an annual which, if true, makes this a rather strange method of propagation.

Edible Uses:
The whole young plant and the semi-succulent leaves are mucilaginous and are used as a pot-herb eaten in soups and sauces. They are especially relished when cooked with groundnuts and tomatoes. In some areas the leaves are said to cause stinging in the mouth and to be not well-liked.

Medicinal Uses:
The leaves are slightly laxative. They are used in traditional medicine to treat a range of complaints. They are given to women after childbirth for their laxative effect; they are used as a treatment for ‘belly palava’ (stomach-ache); when eaten in quantity they are used to treat liver-complaints; they are used as an infusion against colds.

Applied externally, they are made into a poultices to treat burns. The leaf-sap is applied to sore eyes and is also instilled into the eye to remove filaria parasites. They are crushed in water and rubbed into the ear to treat earache.

A trace of alkaloid has been reported present in the leaves.The powdered root has been used prepared as a paste for external application to breast-cancer in Nigeria.

Other Uses : Like garlic, the whole plant has repellent properties to crocodiles.

Cota tinctoria

Botanical Name: Cota tinctoria
Family: Asteraceae
Kingdom:
Plantae
Order: Asterales
Genus: Cota
Species: C. tinctoria

Synonyms:
*Synonymy
*Anthemis tinctoria L. (basionym)
*Anacyclus tinctorius (L.) Samp.
*Anthemis brachyglossa K.Koch
*Anthemis chrysantha Schur
*Anthemis coarctata Sm.
*Anthemis debilis Fed.

Common Names: Golden marguerite, Yellow chamomile, or Oxeye chamomile.

Habitat: Cota tinctoria is native to Europe, the Mediterranean and Western Asia and naturalized in scattered locations in North America.

Description:
Cota tinctoria is an erect, clump-forming, evergreen perennial plant with stems that branch near the base and can become more or less woody. The plant grows around 60cm tall.
The plant is harvested from the wild for local use as a medicine and a dye. It was at one time often grown as a dye plant, though modern synthetic dyes have greatly reduced the use of this species. It is often grown as an ornamental, the plant is especially valued for its flowering display – there are several named varieties.
Human activity, especially the growing of cereals, has led to this plant being spread widely from its original range. As a weed of cereal fields, the seeds were often a contaminant of the grain and were sown where and when the grain was sown. Modern seed screening methods have greatly reduced the spread of this plant, though it has become established in many countries.

Cultivation:
Cota tinctoria is a very hardy plant, tolerating winter temperatures down to about -15°c according in one report, or to about -25°c according to another. It dislikes hot, humid summers.

An easily grown plant, succeeding in a sunny position in most dry to medium soils so long as they are well-drained. It grows well on chalk, but does poorly and is short-lived when grown in heavy, clay soils. It is tolerant of drought and poor soils. Plants succeed in maritime gardens.

This species has formerly been cultivated as a dye plant, the var. ‘Kelawayi’ is said to be the best form.
Plants are often short-lived – they are apt to over-flower and exhaust themselves. It is best to remove the flowering stems as soon as they stop flowering in order to stimulate the production of basal shoots for the following year.

Propagation:
Seed – surface sow early spring in a greenhouse. Do not allow the soil to dry out. Light aids germination. The seed usually germinates in 2 weeks at 20°c. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer.
Cuttings of soft wood early summer in a frame. Very easy.
Division in spring or autumn. Divide the plant every other year in order to maintain vigour.

Medicinal Uses:
The whole plant is antispasmodic, diaphoretic, emetic, emmenagogue and vesicant. It is used internally as a tea, which can be made either from the flowers or the whole plant.

Applied externally, it is used as a poultice on piles and can also be applied to the bath wate.The leaves are rubbed onto insect stings.

Other Uses: A distinctive yellow dye is obtained from the flowers.

Coriaria myrtifolia

Botanical Name: Coriaria myrtifolia
Family: Coriariaceae
Kingdom: Plantae
Order: Cucurbitales
Genus: Coriaria
Species: C. myrtifolia

Synonyms:
*Coriaria hermaphrodita Turra
*Coriaria tinctoria Dulac

Common Names: Redoul, Myrtle-leaved sumach, Myrtle-leaved tanner’s tree, English redoul.

Habitat: Coriaria myrtifolia is native to Europe. It grows in the Mediterranean coastal Spain and Southern France (from the Gironde to the Alpes Maritimes), penetrating into Italy as far as part of the Apennines.It prefers to grow on dry woods, hedges and rocky places.

Description:
Coriaria myrtifolia is a deciduous Shrub growing to 1.8 m (6ft) with branches greyish square section. The leaves are sessile, mostly opposite but sometimes in groups of three or more, oblong, acuminate, with three ribs. The small greenish flowers, which appear from April to June in racemes, have five reddish highlights styles, five sepals and five petals, with ten stamens. The black fruits are formed of five fleshy carpels, each containing one seed.
The species is hermaphrodite (has both male and female organs).

The root nodules of this plant carry out symbiotic nitrogen fixation, Coriaria myrtifolia is one of the 13 Coriaria species known to bear actinorhizae.

CLICK & SEE THE PICTURES

Cultivation:
Prefers a fairly good loamy soil in a sunny sheltered position. Succeeds in light shade[200]. Plants are hardy to about -5°c, succeeding outdoors in Britain from London and south-westwards. The stems are often cut back by winter cold but the plants usually resprout from the base. This new growth does not flower in its first year. The roots of plants in this genus bear nitrogen-fixing nodules[218]. Whilst much of the nitrogen will be utilized by the growing plant, some of it will become available for other plants growing nearby.

Propagation:
Seed – sow February/March in a greenhouse. The seed usually germinates in 1 – 3 months at 15°c. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7cm with a heel, July/August in a frame. Fair percentage[

Uses:
Traditionally, leaves of redoul were intensively collected for their tannin content, for tanning and dyeing purposes. During the medieval period, ecclesiastical institutions and the aristocracy clearly sought to establish some royalties on this resource, the samples are being especially on the distribution and sale of material first. These uses are due to the wealth of Coriaria spp tannin, particularly concentrated in the root and the bark of the stem, but also present in leaves, where they coexist with yellow dyes from the chemical group of flavonoids. These tannins are part of the group of hydrolyzable tannins, such as gall tannins. The chemical composition of redoul thus makes a tanning substance, capable of transforming recently flayed animal skins into leather, which is rot resistant, flexible and relatively impermeable, known as Basil leather. These properties allow for its widespread use in many industries. Moreover, the well-known chemical reaction of tannins with iron salts, producing black precipitates, is the basis for the manufacture of some inks used since the Middle Ages, and is also used to dye a variety of textiles black or gray. Until the mid-fourteenth century, the material was the subject of extensive trade between the north of Catalonia and Languedoc. The M?ori used species of Coriaria from New Zealand: they produced traditional tattoo inks from the fruit juice, made musical instruments from the hollow stems, and despite its extreme toxicity ate the fruit sparingly due to its sweet taste; using it to sweeten drinking water or jellies made from seaweed.

Coriaria myrtifolia is also used as an ornamental plant,

Known Hazards: This plant is very poisonous, the poison having the same effect as alcoholic intoxication.
