Cultivation:
Requires a hot, well-drained dry position in full sun. Plants are tolerant of drought. Tolerates a pH in the range 6.3 to 8.3. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. A perennial species, this plant produces annual stems from a woody base. The flowers open in the early morning and fade by midday. Capers are often cultivated in tropical and sub-tropical zones for their aromatic flower buds, which are used as a condiment, they are also frequently gathered from the wild. There are some named varieties, the most commonly cultivated form tends to be the spineless C. spinosa inermis. Special Features: Not North American native, Invasive, Attractive flowers or blooms.

Propagation :
Seed – best sown as soon as it is ripe in a greenhouse. Prick out the seedlings into individual pots of well-drained soil when they are large enough to handle. Grow on the young plants for at least their first winter in a greenhouse and plant out in late spring or early summer. Cuttings of half-ripe wood, July/August in sand in a cold frame.

Edible Uses: The flower buds are pickled and used as a flavouring in sauces, salads etc. The young fruits and tender branch tips can also be pickled and used as a condiment. The flower buds are harvested in the early morning and wilted before pickling them in white vinegar. Young shoots – cooked and used like asparagus.  CLICK  & SEE  THE PICTURES

Medicinal Uses:
Analgesic; Anthelmintic; Antihaemorrhoidal; Aperient; Deobstruent; Depurative; Diuretic; Emmenagogue; Expectorant; Tonic; Vasoconstrictor.
The root-bark is analgesic, anthelmintic, antihaemorrhoidal, aperient, deobstruent, depurative, diuretic, emmenagogue, expectorant, tonic and vasoconstrictive. It is used internally in the treatment of gastrointestinal infections, diarrhoea, gout and rheumatism. Externally, it is used to treat skin conditions, capillary weakness and easy bruising. The bark is harvested in the autumn and dried for later use. The stem bark is bitter and diuretic. If taken before meals it will increase the appetite. The unopened flower buds are laxative. They are used internally in the treatment of coughs, and externally to treat eye infections. The buds are a rich source of compounds known as aldose-reductose inhibitors – it has been shown that these compounds are effective in preventing the formation of cataracts. The buds are harvested before the flowers open and can be pickled for later use – when prepared correctly they are said to ease stomach pain. A decoction of the plant is used to treat vaginal thrush. The leaves are bruised and applied as a poultice in the treatment of gout.

The unopened flower buds are laxative and, if prepared correctly with vinegar, are thought to ease stomach pain. The bark is bitter and diuretic, and can be taken immediately before meals to increase the appetite. The root bark is purifying and stops internal bleeding. It is used to treat skin conditions, capillary weakness, and easy bruising, and is also used in cosmetic preparations. A decoction of the plant is used to treat yeast and vaginal infections such as candidiasis. Capers are an appetizer and digestive. Since ancient times, caper poultices have been used to ease swellings and bruises and this led to the belief that rutin had properties affecting the permeability of the blood capillaries; such as reducing their fragility though clinical evidence is inconclusive .

Other Uses: An extract of the root is used as a cosmetic and is particularly useful in treating rose-coloured rashes and capillary weaknesses. The plant is used as Landscaping :Cascades, Container, Erosion control, Ground cover.

Botanical Name ; Fagopyrum esculentum
Family: Polygonaceae
Genus: Fagopyrum
Species: F. esculentum
Kingdom: Plantae
Order: Caryophyllales

Synonyms : Fagopyrum sagittatum. Fagopyrum vulgare.

Common Name:Buckwheat

Habitat : Fagopyrum esculentum is native to Central Asia.  It occurs  occasional casual in Britain. It grows in waste ground as an escape from cultivation. Its original habitat is obscure.

Description:
Fagopyrum esculentum is an annual plant, growing to 1.5 m (5ft) by 0.3 m (1ft in) at a fast rate.
It is frost tender. It is in flower from Jul to September, and the seeds ripen from Aug to October. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Bees, flies.It is noted for attracting wildlife.

It is a plant cultivated for its grain-like seeds, and also used as a cover crop. To distinguish it from a related species, Fagopyrum tataricum that is also cultivated as a grain in the Himalayas, and from the less commonly cultivated Fagopyrum acutatum, it is also known as Japanese buckwheat and silverhull buckwheat.

Despite the name, buckwheat is not related to wheat, as it is not a grass. Instead, buckwheat is related to sorrel, knotweed, and rhubarb. Because its seeds are eaten and rich in complex carbohydrates, it is referred to as a pseudocereal. The cultivation of buckwheat grain declined sharply in the 20th century with the adoption of nitrogen fertilizer that increased the productivity of other staples.

Cultivation:
A very easily grown plant, it prefers dry sandy soils but succeeds in most conditions including poor, heavy  or acid soils and even sub-soils. Prefers a cool moist climate, but it also succeeds in dry and arid regions. Buckwheat is frequently cultivated for its edible seed and leaves, it can produce a seed crop in 100 days from sowing and a crop of leaves in 8 weeks. There are some named varieties. The seed ripens irregularly over a period of several weeks so it is difficult to harvest. Plants have poor frost resistance but they are disease and insect resistant. They inhibit the growth of winter wheat. The flowers have a pleasant sweet honey scent and are extremely attractive to bees and hoverflies.

Propagation:
Seed – sow from the middle of spring to early summer in situ. The seed usually germinates in 5 days. The earlier sowings are for a seed or leaf crop whilst the later sowings are used mainly for leaf crops or green manure.

Edible Uses:
Edible Parts: Leaves;   Seed.

Leaves – raw or cooked like spinach. Not that wonderful raw, they improve somewhat with cooking. The leaves are rich in rutin (see below for more details) and so are a very healthy addition to the diet. Seed – raw or cooked. A nutty flavour, though it has a somewhat gritty texture. The seed can be soaked overnight in warm water then sprouted for a few days and added to salads. It can also be ground into a powder and used as a cereal when it can be made into pancakes, noodles, breads etc or be used as a thickening agent in soups etc. Rich in vitamin B6. An excellent beer can be brewed from the grain.

Medicinal Uses:

Acrid; Astringent; Galactogogue; Vasodilator.

Buckwheat is a bitter but pleasant tasting herb that is frequently used medicinally because the leaves are a good source of rutin. Rutin is useful in the treatment of a wide range of circulatory problems, it dilates the blood vessels, reduces capillary permeability and lowers blood pressure. The leaves and shoots of flowering plants are acrid, astringent and vasodilator. It is used internally in the treatment of high blood pressure, gout, varicose veins, chilblains, radiation damage etc. It is best used in conjunction with vitamin C since this aids absorption. Often combined with lime flowers (Tilia species), it is a specific treatment for haemorrhage into the retina. The leaves and flowering stems are harvested as the plant begins to flower and are dried for later use. They should be stored in the dark because the active ingredients rapidly degrade in the light. Some caution should be exercised in the use of this herb because it has been known to cause light-sensitive dermatitis. An infusion of the herb has been used in the treatment of erysipelas (an acute infectious skin disease). A homeopathic remedy has been made from the leaves. It is used in the treatment of eczema and liver disorders.

Buckwheat is used to treat a wide range of circulatory problems. It is best taken as a tea or tablet, accompanied by vitamin C or lemon juice to aid absorption. Buckwheat is used particularly to treat fragile capillaries, but also helps strengthen varicose veins and heal chilblains. Often combined with linden flowers, buckwheat is a specific treatment for hemorrhage into the retina. The leaves and shoots of flowering plants are acrid, astringent and vasodilator. It is used internally in the treatment of high blood pressure, gout, varicose veins, chilblains, radiation damage etc. A poultice made from the seeds has been used for restoring the flow of milk in nursing mothers. An infusion of the herb has been used in the treatment of erysipelas (an acute infectious skin disease).

Other Uses:
Dye; Green manure; Soil reclamation…………..A very good green manure plant, it can be used to reclaim badly degraded soils and subsoils.  A blue dye is obtained from the stems. A brown dye is obtained from the flowers.

Known Hazards : This plant has caused photosensitivity in some people, only the dehusked grain is considered to be safe.

Ginkgo biloba

[amazon_link asins=’B00016R3DA,B008OPK8EQ’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’8e8e42f0-fa59-11e6-81be-7df47ad492e9′]

Botanical Name : Ginkgo biloba
Kingdom: Plantae
Division: Ginkgophyta
Class: Ginkgoopsida
Order: Ginkgoales
Family: Ginkgoaceae
Genus: Ginkgo
Species: G. biloba

Synonyms : Salisburia adiantifolia. Pterophyllus salisburiensis. Ginkgo macrophylla. Salisburia biloba

Common Names: Ginkgo, Maidenhair tree ,
Chinese: Pinyin: Yínxìng; Japanese pronunciation: Icho, Ginnan; Korean: Romaja: Eunhaeng; Vietnamese: Bach quo, Acceptable variant gingko

Habitat :Ginkgo biloba is native to E. Asia – N. China. Found wild in only 2 localities at Guizhou and on the Anhui/Zhejiang border, where it grows on rich sandy soils
Description:
Ginkgos are large deciduous trees, normally reaching a height of 20–35 m (66–115 ft), with some specimens in China being over 50 m (160 ft). The tree has an angular crown and long, somewhat erratic branches, and is usually deep rooted and resistant to wind and snow damage. Young trees are often tall and slender, and sparsely branched; the crown becomes broader as the tree ages. During autumn, the leaves turn a bright yellow, then fall, sometimes within a short space of time (one to 15 days). A combination of resistance to disease, insect-resistant wood and the ability to form aerial roots and sprouts makes ginkgos long-lived, with some specimens claimed to be more than 2,500 years old.

Bloom Color: Green. Main Bloom Time: Early spring, Late spring, Mid spring. Ginkgo is a unique species of tree with no close living relatives and is one of the best-known examples of a living fossil.

Ginkgo is a relatively shade-intolerant species that (at least in cultivation) grows best in environments that are well-watered and well-drained. The species shows a preference for disturbed sites; in the “semiwild” stands at Tian Mu Shan, many specimens are found along stream banks, rocky slopes, and cliff edges. Accordingly, ginkgo retains a prodigious capacity for vegetative growth. It is capable of sprouting from embedded buds near the base of the trunk (lignotubers, or basal chi chi) in response to disturbances, such as soil erosion. Old individuals are also capable of producing aerial roots on the undersides of large branches in response to disturbances such as crown damage; these roots can lead to successful clonal reproduction upon contacting the soil. These strategies are evidently important in the persistence of ginkgo; in a survey of the “semiwild” stands remaining in Tianmushan, 40% of the specimens surveyed were multistemmed, and few saplings were present.

China,the tree is widely cultivated and was introduced early to human history. It has various uses in traditional medicine and as a source of food

Cultivation:
Landscape Uses:Firewood, Pest tolerant, Specimen, Street tree. Succeeds in most soil types so long as they are well-drained, though it prefers a rather dry loam in a position sheltered from strong winds. Some of the best specimens in Britain are found growing on soils over chalk or limestone. Plants flower and fruit more reliably after hot summers or when grown in a warm sunny position. Established plants are drought resistant, they also tolerate atmospheric pollution. Plants can grow in poor hard-packed soil, making the male forms good candidates for street planting. Trees are often used for street planting in towns, only the males are used because the fruit from female plants has a nauseous smell. The fruit contains butanoic acid, it has the aroma of rancid butter. Ginkgo is a very ornamental plant and there are several named forms. This species is the only surviving member of a family that was believed to be extinct until fairly recent times. It has probably remained virtually unchanged for at least 150 million years and might have been growing when the dinosaurs were roaming the earth. It is exceptional in having motile sperm and fertilization may not take place until after the seed has fallen from the tree. This genus belongs to a very ancient order and has affinities with tree ferns and cycads. The ginkgo is usually slow growing, averaging less than 30cm per year with growth taking place from late May to the end of August. Growth is also unpredictable, in some years trees may not put on any new growth whilst in others there may be 1 metre of growth. This variability does not seem to be connected to water or nutrient availability. Trees are probably long-lived in Britain, one of the original plantings (in 1758) is still growing and healthy at Kew (1993). Plants are not troubled by insects or diseases, have they evolved a resistance?. Ginkgo is a popular food and medicinal crop in China, the plants are often cultivated for this purpose and are commonly grown in and around temples. Plants are either male or female, one male plant can pollinate up to 5 females. It takes up to 35 years from seed for plants to come into bearing. Prior to maturity the sexes can often be distinguished because female plants tend to have almost horizontal branches and deeply incised leaves whilst males have branches at a sharper angle to the trunk and their leaves are not so deeply lobed. Branches of male trees can be grafted onto female frees in order to fertilize them. When a branch from a female plant was grafted onto a male plant at Kew it fruited prolifically. Female trees have often been seen in various gardens with good crops of fruit. Seeds are marked by two or three longitudinal ridges, it is said that those with two ridges produce female plants whilst those with three ridges produce male plants. Trees can be coppiced. They can also be pruned into a fan-shape for growing on walls. Another report says that the trees dislike pruning and will often die back as a result. Special Features:Attractive foliage, Not North American native, Fragrant flowers, Inconspicuous flowers or blooms, Flowers have an unpleasant odor.

Propagation:
Seed – best sown as soon as it is ripe in a cold frame or in a sheltered outdoor bed. The seed requires stratification according to one report whilst another says that stratification is not required and that the seed can be sown in spring but that it must not have been allowed to dry out. Germination is usually good to fair. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in the greenhouse for their first year. Plant them out into their permanent positions in the following spring and consider giving them some protection from winter cold for their first winter outdoors. Softwood cuttings in a frame in spring. Cuttings of half-ripe wood, July/August in a frame. The cutting may not grow away in its first year but usually grows all right after that. Cuttings of mature wood, December in a frame.
Edible Uses: Oil; …...click & see

Seed – raw (in small quantities), or cooked. A soft and oily texture, the seed has a sweet flavour and tastes somewhat like a large pine nut. The baked seed makes very pleasant eating, it has a taste rather like a cross between potatoes and sweet chestnuts. The seed can be boiled and used in soups, porridges etc…CLICK  & SEE  It needs to be heated before being eaten in order to destroy a mildly acrimonious principle. Another report says that the seed can be eaten raw whilst another says that large quantities of the seed are toxic. See the notes above on toxicity for more details. The raw seed is said to have a fish-like flavour. The seed is rich in niacin. It is a good source of starch and protein, but is low in fats. These fats are mostly unsaturated or monosaturated. A more detailed nutritional analysis is available. An edible oil is obtained from the seed

Ginkgo has a long history of medicinal use in traditional Chinese medicine, where the seed is most commonly used. These uses are mentioned in more detail later. Recent research into the plant has discovered a range of medicinally active compounds in the leaves and this has excited a lot of interest in the health-promoting potential of the plant. In particular, the leaves stimulate the blood circulation and have a tonic effect on the brain, reducing lethargy, improving memory and giving an improved sense of well-being. They have also been shown to be effective in improving peripheral arterial circulation and in treating hearing disorders such as tinnitus where these result from poor circulation or damage by free radicals. The leaves contain ginkgolides, these are compounds that are unknown in any other plant species. Ginkgolides inhibit allergic responses and so are of use in treating disorders such as asthma. Eye disorders and senility have also responded to treatment. The leaves are best harvested in the late summer or early autumn just before they begin to change colour. They are dried for later use. The fruit is antibacterial, antifungal, astringent, cancer, digestive, expectorant, sedative, vermifuge. The fruit is macerated in vegetable oil for 100 days and then the pulp is used in the treatment of pulmonary tuberculosis, asthma, bronchitis etc. (This report might be referring to the seed rather than the fleshy fruit). The cooked seed is antitussive, astringent and sedative. It is used in the treatment of asthma, coughs with thick phlegm and urinary incontinence. The raw seed is said to have anticancer activity and also to be antivinous. It should be used with caution, however, due to reports of toxicity. The cooked seeds stabilize spermatogenesis.
Other Uses: Oil; Oil; Soap; Wood…….An oil from the seed is used as a fuel in lighting. A soap substitute is produced by mixing the pulp of the seed (is the fruit meant here?) with oil or wine. Wood – light, soft, it has insect repelling qualities.

Known Hazards: The seed contains a mildly acrimonious principle that is unstable when heated. It is therefore best to cook the seed before eating it to ensure any possible toxicity is destroyed. This acrimonious principle is probably 4′-methoxypyridoxine, which can destroy vitamin B6. It is more toxic for children, but the raw nuts would have to be eaten often over a period of time for the negative effects to become apparent. Avoid if known allergy to Ginkgo or cross-react species (cashew, poison ivy). Not recommended for children. Avoid if on blood thinning medication (e.g. warfarin). Discontinue prior to surgery. Avoid parenteral use as possible hypotension, shock, dizziness. Excessive seed ingestion can cause ‘gin-man’ food poisoning.

It is not frost tender. It is in flower from Apr to May, and the seeds ripen from Jun to July. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Insects.The plant is not self-fertile.

CLICK & SEE THE PICTURES : 
Cultivation:
Prefers a fertile, well-drained, moisture retentive soil in a sunny position. Tolerates semi-shade though fruit production will be reduced. Grows best near the coast. Plants like a mulch of pine or spruce leaves. Cultivated for its edible fruit in the Andes. This species, along with F. virginiana, is probably a parent of the cultivated strawberries. Dioecious. Male and female plants must be grown if seed is required.

Propagation:
Seed – sow early spring in a greenhouse. The seed can take 4 weeks or more to germinate. The seedlings are very small and slow-growing at first, but then grow rapidly.

Guaiacum officinale

 

Botanical Name: Guaiacum officinale
Family: Zygophyllaceae
Genus: Guaiacum
Species: G. officinale
Kingdom: Plantae
Order: Zygophyllales
Synonym: Lignum Vitae.

Common Names: Roughbark lignum-vitae, Guaiacwood or Gaïacwood

Habitat: Guaiacum officinale is native to the Caribbean and the northern coast of South America.

Description:
Guaiacum officinale is a small tree. It grows very slowly , reaching about 10 m in height with a trunk diameter of 60 cm. The tree is essentially evergreen throughout most of its native range. The leaves are compound, 2.5 to 3 cm in length, and 2 cm wide. The blue flowers have five petals that yield a bright-yellow-orange fruit with red flesh and black seeds….click & see the pictures

The tree blooms with pretty rich blue flowers, the trunk is a greenish-brown colour, stem almost always crooked, bark furrowed; the wood is extraordinarily heavy, solid and dense, fibres cross-grained; pinnate leaves, oval obtuse; fruit obcordate capsule seeds solitary, hard, oblong. The old heart wood is dark green, the sap wood little in quantity and of a much lighter yellowish colour; the wood is largely used by turners, where weight is not an obstacle; it is very hard and durable, suitable for making black sheaves, pestles, pulleys, rulers, skittle boards, etc.; it has a slight acrid taste and is odourless, unless heated, when it emits an agreeable scent. The bark yields 1 per cent volatile oil of delicious fragrance.

Guaiacum officinale is the national flower of Jamaica

Parts Used: Resin, bark & wood.

Medicinal Uses:
The wood is very little used in medicine; it obtained a great reputation about the sixteenth century, when it was brought into notice as a cure for syphilis and other diseases; later on the resin obtained from the wood was introduced and now is greatly preferred, for medicinal use, to the wood. The wood is sometimes sold by chemists in the form of fine shavings, and as such called Lignum Vitae, which are turned green by exposure to the air, and bluish green by the action of nitric fumes. This test proves its genuiness.

It is a mild laxative and diuretic. For tonsilitis it is given in powdered form. Specially useful for rheumatoid arthritis, also in chronic rheumatism and gout, relieving the pain and inflammation between the attacks, and lessening their recurrence if doses are continued. It acts as an acrid stimulant, increasing heat of body and circulation; when the decoction is taken hot and the body is kept warm, it acts as a diaphoretic, and if cool as a diuretic. Also largely used for secondary syphilis, skin diseases and scrofula.

Other Uses:
The leaves are sometimes used as a substitute for soap.

Guaiacum Resin. This is obtained from both the above trees and is procured by raising one end of the log and firing it; this melts the resin, which runs out of a hole cut in the other end, and is then caught into vessels. The resin is found in round or ovoid tears; some are imported the size of walnuts, but usually it is in large blocks; these break easily; the fracture is clean and glassy, in thin pieces, colour yellow-reddish brown. The powder is grey, and must be kept in dark-coloured bottles, as exposure to the light and air soon turns it green.
