Prunus cerasoides

Botanical Name : Prunus cerasoides
Family: Rosaceae
Genus: Prunus
Subgenus: Cerasus
Species: P. cerasoides
Kingdom: Plantae
Order: Rosales

Synonyms:
*Prunus majestica Koehne
*Prunus puddum Franch.

Common Names: Wild Himalayan cherry or Sour cherry

Habitat : Prunus cerasoides is native to E. Asia – Himalayas from Himachel Pradesh to S.W. China and Burma. It grows in the forests, 1200 – 2400 metres. Forests in ravines at elevations of 700 – 3700 metres in western China.
Description:
Prunus cerasoides is a deciduous Tree growing to 30 m (98ft 5in). It has glossy, ringed bark. When the tree is not in flower, it is characterised by glossy, ringed bark and long, dentate stipules.

The tree flowers in autumn and winter. Flowers are pinkish white in color. It has ovoid yellow fruit that turns red as it ripens.

The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
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. Requires an open sunny sheltered position. Not very hardy in Britain but it succeeds outdoors in the milder areas of the country. 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. 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. 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. Acid and astringent, they are only occasionally eaten raw but are more often cooked. The fruit is about 15mm in diameter and contains one large seed. Gum – chewed. Obtained from the trunk, it can be employed as a substitute for gum tragacanth, see Astragalus spp. Seed – raw or cooked. Do not eat the seed if it is too bitter – see the notes below on toxicity.

Medicinal Uses:
The fruit is astringent. The juice of the bark is applied externally to treat backaches. 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:
Beads; Dye; Gum; Wood.

A green dye can be obtained from the leaves. A dark grey to green dye can be obtained from the fruit. The seeds are used as beads in necklaces and rosaries. Wood – moderately hard, strong, durable, aromatic. The branches are used as walking sticks
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.

Prunus caroliniana

Botanical Name : Prunus caroliniana
Family: Rosaceae
Genus: Prunus
Species: P. caroliniana
Kingdom: Plantae
Order: Rosales

Synonyms: Laurocerasus caroliniana. (Mill.)Roem.

Common Names: American Cherry Laurel, Carolina laurelcherry, Laurel Cherry, Cherry laurel, or Carolina cherry

Habitat : Prunus caroliniana is native to the lowlands of Southeastern United States, from North Carolina south to Florida and westward to central Texas. The species has also escaped into the wild in a few places in California. It grows on deep, well-drained rich moist bottomlands, bluffs or streambanks.
Description:
Prunus caroliniana is a small to medium-sized evergreen tree which grows to about 5–13 meters (16–43 ft) tall, with a spread of about 6–9 meters (20–30 ft). The leaves are dark green, alternate, shiny, leathery, elliptic to oblanceolate, 5–12 cm (2–4.5 in) long, usually with an entire (smooth) margin, but occasionally serrulate (having subtle serrations), and with cuneate bases. Reproductively mature trees have entire margins, whereas immature ones often have subtle serrations. The twigs are red to grayish brown, slender, and glabrous.

Fragrant white to cream-colored flowers are produced in racemes (stalked bunches) 5–8 cm (2–3 in) long in the late winter to early spring. The fruits are tiny black cherries about 1 cm (0.5 in) in diameter, which persist through winter and are primarily consumed by birds (February – April).
It is in leaf 12-Jan It is in flower from Apr to May, and the seeds ripen in October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil. The plant can tolerates strong winds but not maritime exposure.
Characteristics:
The leaves and branches contain high amounts of cyanogenic glycosides that break down into hydrogen cyanide when damaged, making it a potential toxic hazard to grazing livestock and children. Due to this, it is considered highly deer-resistant. When crushed, its leaves and green twigs emit a fragrance described as resembling maraschino cherries or almond extract..

Cultivation:
Landscape Uses:Pest tolerant, Screen, Standard, Street tree, Woodland garden. Requires a well-drained moisture retentive soil.   Succeeds in a hot dry position. Succeeds in light shade but fruits better in a sunny position. Thrives in a loamy soil, doing well on limestone.  Prefers some chalk in the soil but apt to become chlorotic if too much is present. Fairly wind-resistant[200]. One report says that this species is tender in most of Britain, whilst another says that it succeeds in climatic zone 7 (tolerating frosts down to about -15°c). A fast-growing but short-lived tree. 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. Special Features:North American native, Naturalizing, All or parts of this plant are poisonous, Fragrant flowers, Attractive flowers or blooms.
Propagation:
Seed – requires 2 – 3 months cold stratification and is best sown in a cold frame as soon as it is ripe. Sow stored seed in a cold frame as early in the year as possible.

Edible Parts: Fruit; Seed.
The fruit might be edible. It has a thick skin and a thin dry flesh[82] and is not edible. It is slightly toxic to humans. 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 below 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.
