Botanical Name : Prunus lauroceerasus
Family: Rosaceae
Genus: Prunus
Subgenus: Cerasus, or Laurocerasus
Section: Laurocerasus
Species: P. laurocerasus
Kingdom: Plantae
Order: Rosales

Common Names:Cherry Laurel,English laurel

Habitat :Prunus lauroceerasus is native to regions bordering the Black Sea in southwestern Asia and southeastern Europe, from Albania and Bulgaria east through Turkey to the Caucasus Mountains and northern Iran

Description:
Prunus laurocerasus is an evergreen shrub or small tree, growing to 5–15 metres (16–49 ft) tall, rarely to 18 metres (59 ft) tall, with a trunk up to 60-cm broad. The leaves are dark green, leathery, shiny, (5–)10–25(–30)-cm wide and 4–10-cm broad, with a finely serrated margin. The leaves can have the smell of almonds when crushed.

The fruit is a small cherry 1–2-cm broad, turning black when ripe in early autumn.   Unlike the rest of the plant, which is poisonous, the cherries are edible, although rather bland and with a somewhat dry smack compared to the fruit of apricots, true cherries, plums, and peaches, to which it is related. The seeds contained within the berries are poisonous like the rest of the plant, containing cyanogenic glycosides and amygdalin.[6] This chemical composition is what gives the smell of almonds when the leaves are crushed.

Cultivation:
Prunus laurocerasus is a widely cultivated ornamental plant, used for planting in gardens and parks in temperate regions worldwide. It is often used for hedges, a screening plant, and as a massed landscape plant. Most cultivars are tough shrubs that can cope with difficult growing conditions, including shaded and dry conditions, and which respond well to pruning.

Medicinal Uses:
The fresh leaves are of value in the treatment of coughs, whooping cough, asthma, dyspepsia and indigestion. Externally, a cold infusion of the leaves is used as a wash for eye infections.  A reliable sedative and frequently the principal agent in cough medicine.  Cherry-laurel water (Aqua Laurocerasi) is produced by distillation. In homeopathy, a tincture produced from the leaves is used as a sedative.  It may also be used externally in soothing poultices.

Other uses
Laurel water, a distillation made from the plant, has a pharmacological usage. The foliage is also used for cut greenery in floristry.

Wild Cherry(Prunus serotina)

Botanical Name ;Prunus serotina
Family: Rosaceae
Genus: Prunus
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Rosales
Subgenus: Cerasus
Species: P. avium
Common NamesWild Cherry , Black Cherry, chokecherry
Parts Used: bark, fruit

Habitat :Native to Europe, northwest Africa, and western Asia, from the British Isles   south to Morocco and Tunisia, north to the Trondheimsfjord region in Norway and east to the Caucasus, and northern Iran, with a small disjunct population in the western Himalaya. The sweet cherry originated in northern Iran. This species has a diploid set of sixteen chromosomes (2n=16). All parts of the plant except for the ripe fruit are slightly toxic, containing cyanogenic glycosides.

Description:
It is a deciduous tree growing to 15–32 m tall, with a trunk up to 1.5 m diameter. Young trees show strong apical dominance with a straight trunk and symmetrical conical crown, becoming rounded to irregular on old trees. The bark is smooth purplish-brown with prominent horizontal grey-brown lenticels on young trees, becoming thick dark blackish-brown and fissured on old trees. The leaves are alternate, simple ovoid-acute, 7–14 cm long and 4–7 cm broad, glabrous matt or sub-shiny green above, variably finely downy beneath, with a serrated margin and an acuminate tip, with a green or reddish petiole 2–3.5 cm long bearing two to five small red glands. The tip of each serrated edge of the leaves also bear small red glands.  In autumn, the leaves turn orange, pink or red before falling. The flowers are produced in early spring at the same time as the new leaves, borne in corymbs of two to six together, each flower pendent on a 2–5 cm peduncle, 2.5–3.5 cm diameter, with five pure white petals, yellowish stamens, and a superior ovary; they are hermaphroditic, and pollinated by bees. The fruit is a drupe 1–2 cm in diameter (larger in some cultivated selections), bright red to dark purple when mature in mid summer, edible, variably sweet to somewhat astringent and bitter to eat fresh; it contains a single hard-shelled stone 8–12 mm long, 7–10 mm wide and 6–8 mm thick, grooved along the flattest edge; the seed (kernel) inside the stone is 6–8 mm long.

The fruit are readily eaten by numerous birds and mammals, which digest the fruit flesh and disperse the seeds in their droppings. Some rodents, and a few birds (notably the Hawfinch), also crack open the stones to eat the kernel inside. All parts of the plant except for the ripe fruit are slightly toxic, containing cyanogenic glycosides.

The leaves provide food for some animals, including Lepidoptera such as the case-bearer moth Coleophora anatipennella.

The tree exudes a gum from wounds in the bark, by which it seals the wounds to exclude insects and fungal infections.

Wild cherry has been known as Gean or Mazzard (also ‘massard’), both largely obsolete names in modern English, though more recently ‘Mazzard’ has been used to refer to a selected self-fertile cultivar that comes true from seed, and which is used as a seedling rootstock for fruiting cultivars.The name “wild cherry” has also been applied in a general or colloquial sense to other species of Prunus growing in their native habitats, particularly to Black Cherry Prunus serotina. Literally,. the scientific name Prunis avium means “bird cherry”, which as a common name typically refers to P. padus though.

Some eighteenth and nineteenth century botanical authors ascribed an origin to western Asia based on the writings of Pliny; however, archaeological finds of seeds from prehistoric Europe contradict this view .

Cultivation:
As the main ancestor of the cultivated sweet cherry, the Wild cherry is one of the two cherry species which supply most of the world’s commercial cultivars of edible cherry (the other is the Sour cherry Prunus cerasus, mainly used for cooking; a few other species have had a very small input). Various cherry cultivars are now grown worldwide wherever the climate is suitable; the number of cultivars is now very large. The species has also escaped from cultivation and become naturalised in some temperate regions, including southwestern Canada, Japan, New Zealand, and the northeast and northwest of the United States.

Plants grown from seeds harvested in classified French stands,recently, plants grown from seeds harvested in seed orchards, cultivars propagated by vegetative methods (cuttings, root cuttings).

Medicinal Uses:
Common Uses: Bronchitis * Colds * Congestion/Chest & Sinus * Cough * Insomnia *
Properties:
Anti-inflammatory* Astringent* Sedative* Expectorant* Antiscrofulous*

Constituents: acetylcholine, hcn, kaempferol, p-coumaric acid, prunasin, quercetin, scopoletin, tannins

Black cherry is an very effective herbal cough remedy. The main use of the bark main use is to still irritated, nagging coughs. Black cherry is used in many commercial cough products such as Smith Brothers, Lunden’s and Vicks for the flavor as well as the decongestant and sedative properties.

Side Effects:
Safe in recommended amounts, but not meant for long term use. Although prussic acid is highly poisonous, if wild cherry bark is used in medicinal doses, the low prussic acid content (0.07-0.16%) ensures that the remedy is quite safe.
How to Use: Wild Cherry
Preparation Methods :Use one teaspoon of the powdered bark to 1 cup of hot water up to 3 times daily as a warm infusion, or 2 teaspoons of bark syrup once daily

Other uses:-

Ornamental

It is often cultivated as a flowering tree. Because of the size of the tree, it is often used in parkland, and less often as a street or garden tree. The double-flowered form, ‘Plena’, is commonly found, rather than the wild single-flowered forms.

Two interspecific hybrids, P. x schmittii (P. avium x P. canescens) and P. x fontenesiana (P. avium x P. mahaleb) are also grown as ornamental trees.

Timber
The hard, reddish-brown wood (cherry wood) is valued as a hardwood for turnery, and making cabinets and musical instruments.

The gum from bark wounds is aromatic and can be chewed as a substitute for chewing gum.

Medicine can be prepared from the stalks of the drupes that is astringent, antitussive, and diuretic.

A green dye can also be prepared from the plant.

Cultural history

Pliny distinguishes between Prunus, the plum fruit, and Cerasus, the cherry fruit. Already in Pliny quite a number of cultivars are cited, some possibly species or varieties, Aproniana, Lutatia, Caeciliana, and so on. Pliny grades them by flavour, including dulcis (“sweet”) and acer (“sharp”).

He goes so far as to say that before the Roman consul Lucius Licinius Lucullus defeated Mithridates in 74 BC, Cerasia … non fuere in Italia, “There were no cherry trees in Italy”. According to him, Lucullus brought them in from Pontus and in the 120 years since that time they had spread across Europe to Britain.

Seeds of a number of cherry species have however been found in Bronze Age and Roman archaeological sites throughout Europe. The reference to “sweet” and “sour” supports the modern view that “sweet” was Prunus avium; there are no other candidates among the cherries found. In 1882 Alphonse de Candolle pointed out that seeds of Prunus avium were found in the Terramare culture of north Italy (1500-1100 BC) and over the layers of the Swiss pile dwellings.[20] Of Pliny’s statement he says (p. 210):

Since this error is perpetuated by its incessant repetition in classical schools, it must once more be said that cherry trees (at least the bird cherry) existed in Italy before Lucullus, and that the famous gourmet did not need to go far to seek the species with the sour or bitter fruit.

De Candolle suggests that what Lucullus brought back was a particular cultivar of Prunus avium from the Caucasus. The origin of cultivars of P. avium is still an open question. Modern cultivated cherries differ from wild ones in having larger fruit, 2–3 cm diameter. The trees are often grown on dwarfing rootstocks to keep them smaller for easier harvesting.

Wild cherries have been an item of human food for several thousands of years. The stones have been found in deposits at bronze age settlements throughout Europe, including in Britain. In one dated example, Wild cherry macrofossils were found in a core sample from the detritus beneath a dwelling at an Early and Middle Bronze Age pile-dwelling site on and in the shore of a former lake at Desenzano del Garda or Lonato, near the southern shore of Lake Garda, Italy. The date is estimated at Early Bronze Age IA, carbon dated there to 2077 plus or minus 10 B.C. The natural forest was largely cleared at that time.

By 800 BC, cherries were being actively cultivated in Asia Minor, and soon after in Greece.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires moist soil.

It is also very suitable in a shrub border as a tall accent. It can be sculptured nicely into a unique form with proper pruning and training and is well suited for container gardening. Regular pruning is needed for best flowering performance. Branches cut in early spring can be forced into bloom indoors.

Cultivation :
Thrives in a well-drained moisture-retentive loamy soil. Prefers some lime in the soil but is likely to become chlorotic if too much lime is present[1]. Succeeds in sun or partial shade though it fruits better when growing in a sunny position. Any pruning is best done soon after the plant has flowered, to within 4 – 5 buds of the previous years wood. This encourages heavier flowering in the following year because it flowers best on the previous years growth. Dormant plants are hardy to about -20°c. Although very hardy, the plant flowers in early spring and it is best grown against a sunny wall in order to give some protection to the flowers. Another report says that plants are not reliably hardy in the open garden[219], which is rather strange considering the plant has been given a hardiness rating of 5. This species is named after a cultivated form grown in gardens, the true wild form is P. triloba simplex. (Bunge.)Rehd[200]. There are some named forms selected for their ornamental value. Most members of this genus are shallow-rooted and will produce suckers if the roots are damaged. Plants in this genus are notably susceptible to honey fungus.

Propagation:
Seed – requires 2 – 3 months cold stratification and is best sown in a cold frame as soon as it is ripe[200]. Sow stored seed in a cold frame as early in the year as possible. Protect the seed from mice etc. The seed can be rather slow, sometimes taking 18 months to germinate. Prick out the seedlings into individual pots when they are large enough to handle. Grow them on in a greenhouse or cold frame for their first winter and plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood with a heel, July/August in a frame. Very easy. Softwood cuttings from strongly growing plants in spring to early summer in a frame. Layering in spring.

Edible Uses:
Edible Parts: Fruit; Seed.

Fruit – raw or cooked. It is possible edible. The fruit is about 13mm in diameter and contains one large seed. Seed – raw or cooked. Do not eat the seed if it is too bitter – see the notes above on toxicity.

Medicinal Uses:
Although no specific mention has been seen for this species, all members of the genus contain amygdalin and prunasin, substances which break down in water to form hydrocyanic acid (cyanide or prussic acid). In small amounts this exceedingly poisonous compound stimulates respiration, improves digestion and gives a sense of well-being.

Other Uses:
Dye.

A green dye can be obtained from the leaves. A dark grey to green dye can be obtained from the fruit.

Known Hazards :   Although no specific mention has been seen for this species, it belongs to a genus where most, if not all members of the genus produce hydrogen cyanide, a poison that gives almonds their characteristic flavour. This toxin is found mainly in the leaves and seed and is readily detected by its bitter taste. It is usually present in too small a quantity to do any harm but any very bitter seed or fruit should not be eaten. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.
