Prunus americana lanata

 

Botanical Name: Prunus americana lanata
Family: Rosaceae
Genus: Prunus
Subgenus:Prunus
Section: Prunocerasus
Species: P. americana
Kingdom: Plantae
Order: Rosales

Synonyms: Prunus lanata. (Sudw.)Mack.&Bush.

Habitat : Prunus americana lanata is native to Central and Southern N. America – Indiana to Illinois, south to Texas. It grows on the hillsides and river bottom lands.

Description:
Prunus americana lanata is a deciduous Tree growing to 10 m (32ft 10in). The leaves are somewhat stout with pubescent, usually glandless petioles; twigs often become somewhat spinelike at the tips. White flowers usually appear before the leaves and are borne in fasicles of two to five on the tip of spur branchlets or from axillary buds formed the previous season. Fruits are yellow to red plums (drupes), at least 0.8 inch (2 cm) long with yellow flesh and a compressed stone. Although this species sometimes produces small, hard plums, the fruits are generally fleshy and highly palatable. Occassionally trees cultivated for plums escape and persist. Horticultural varieties can be distinguished from the native species by their larger petals, smaller flower clusters (one to three per node), and sometimes by the gland-tipped teeth of the leaves.

It is in flower in April, and the seeds ripen in August. 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, doing well on limestone. Prefers some lime in the soil but is likely to become chlorotic if too much lime is present. Succeeds in sun or partial shade though it fruits better in a sunny position. 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. Used mainly in jellies. The fruit is about 25mm in diameter, it has a thick succulent flesh 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; Wood.

A green dye can be obtained from the leaves. A dark grey to green dye can be obtained from the fruit. Wood – heavy, hard, close-grained, strong. The tree is too small for the wood to be of commercial value.

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 mahaleb

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

Common Names :Prunus mahaleb, aka mahaleb cherry, aka St Lucie cherry

Habitat :Prunus mahaleb  is native in the Mediterranean region, Iran and parts of central Asia. It is adjudged to be native in northwestern Europe or at  least it is naturalized there.The tree occurs in thickets and open woodland on dry slopes; in central Europe at altitudes up to 1,700 m, and in highlands at  1,200-2,000 m in southern Europe. It has become naturalised in some temperate areas, including Europe north of its native range (north to Great Britain and  Sweden), and locally in Australia and the United States.

Description:
Prunus mahaleb is a deciduous tree or large shrub, growing to 2–10 m (rarely up to 12 m) tall with a trunk up to 40 cm diameter.The tree’s bark is  grey-brown, with conspicuous lenticels on young stems, and shallowly fissured on old trunks. The leaves are 1.5-5 cm long, 1-4 cm. wide, alternate, clustered at the end of alternately arranged twigs, ovate to cordate, pointed, have serrate edges, longitudinal venation and are glabrous and green. The petiole is  5-20 mm, and may or may not have two glands. The flowers are fragrant, pure white, small, 8-20 mm diameter, with an 8-15 mm pedicel; they are arranged 3-10  together on a 3-4 cm long raceme. The flower pollination is mainly by bees. The fruit is a small thin-fleshed cherry-like drupe 8–10 mm in diameter, green at  first, turning red then dark purple to black when mature, with a very bitter flavour; flowering is in mid spring with the fruit ripening in mid to late  summer……....CLICK & SEE THE PICTURES.

Cultivation:  
Thrives in a well-drained moisture-retentive loamy soil, growing best in a poor soil. Prefers some lime in the soil but is likely to become chlorotic if too much lime is present. Succeeds in sun or partial shade though it fruits better in a sunny position. 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:
The fruit might be edible. The fruits of all members of this genus are more or less edible, may not be always of very good quality. However, if the fruit is bitter it should not be eaten in any quantity due to the presence of toxic compounds. The fruit is about 6mm in diameter and contains one large seed. Seeds are eaten  raw or cooked. The dried seed kernels are used as a flavouring in breads, sweet pastries, confectionery etc. They impart an intriguing flavour. Do not eat the seed if it is too bitter – see the notes above on toxicity.

Medicinal Uses:
The seed is tonic. 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.

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.

Prunus insititia

Botanical Name : Prunus insititia – L.
Family  Rosaceae
Kingdom: Plantae
Order: Rosales
Genus: Prunus
Subgenus: Prunus
Section: Prunus
Species: P. domestica
Subspecies: P. domestica subsp. insititia

Synonyms:     Bully-bloom (for the flowers). Bullies, Bolas, Bullions and Wild Damson (for the fruit).
(French) Sibarelles.

Common Name :  Damson or damson plum,Prunus domestica subsp

Habitat:  Common in England in thickets, woods and hedges, though more rare in Scotland and probably not wild north of the Forth and Clyde. Common in South-East Europe and in Northern and Central Asia.

Description:
Prunus insititia is a tall shrub, sometimes developing into a small tree about 15 feet high. Resembles the Blackthorn or Sloe (Prunus spinosa), but is less thorny and has straight, not crooked branches, covered by brown, not black bark, only a few of the old ones terminating in spines, the younger ones downy. It has also larger leaves than the Blackthorn, downy underneath, alternate, finely-toothed, on short, downy foot-stalks, and flowers, white like those of the Blackthorn, but larger, with broader petals, borne in less crowded clusters and not on the naked branches, but expanding just after the leaves have begun to unfold.

The globular, fleshy fruit, marked with a faint suture, has generally a black skin, covered with a thin bluish bloom, and is similar to the Sloe, but larger, often an inch across, and drooping from its weight, not erect as the Sloe. Occasionally yellow varieties are found.

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[200]. 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. More acid than a plum but it is very acceptable raw when fully ripe, especially after being touched by frost. The fruit is about 3cm 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.

Constituents:  The volatile oil expressed from the seeds contains benzaldehyde and hydrocyanic acid. These substances are also present in the young leaves and flowers.

Medicinal Uses:
Febrifuge;  Purgative;  Styptic.

The bark of the root and branches is febrifuge and considerably styptic. An infusion of the flowers has been used as a mild purgative for children. 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;  Hedge;  Hedge;  Shelterbelt.

A green dye can be obtained from the leaves. A dark grey to green dye can be obtained from the fruit. Trees are fairly wind resistant and can be grown as a shelterbelt hedge.

Cultivation:   
Requires a well-drained moisture retentive soil. Succeeds in light shade but fruits better in a sunny position. Thrives in a loamy soil, doing well on limestone. Grows well in heavy clay soils. Prefers some chalk in the soil but apt to become chlorotic if too much is present. Occasionally cultivated for its edible fruit, there are some named varieties. It has been derived in cultivation from the bullace, differing in having a sweeter fruit. Damsons can be grown successfully against a north facing wall. 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.

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.

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.
