Abies concolor

Botanical Name: Abies concolor
Family: Pinaceae
Genus: Abies
Species: A. concolor
Kingdom: Plantae
Division: Pinophyta
Class: Pinopsida
Order: Pinales

Synonyms : Picea concolor.

Common Names: Colorado Fir, White fir

Habitat :Abies concolor is a fir native to the mountains of western North America(Oregon to California, to Arizona and New Mexico.), occurring at elevations of 900–3,400 m (3,000–11,200 ft).It is found on a wide range of soils, but preferring moist soils with a humid climate and a long winter from 700 metres to 3,400 metres.
Description:
Abies concolor is a medium to large evergreen coniferous tree growing to 25–60 m (82–197 ft) tall and with a trunk diameter of up to 2 m (6.6 ft).
The leaves are needle-like, flattened, 2.5–6 cm long and 2 mm wide by 0.5–1 mm thick, green to glaucous blue-green above, and with two glaucous blue-white bands of stomatal bloom below, and slightly notched to bluntly pointed at the tip. The leaf arrangement is spiral on the shoot, but with each leaf variably twisted at the base so they all lie in either two more-or-less flat ranks on either side of the shoot, or upswept across the top of the shoot but not below the shoot.

The cones are 6–12 cm long and 4–4.5 cm broad, green or purple ripening pale brown, with about 100–150 scales; the scale bracts are short, and hidden in the closed cone. The winged seeds are released when the cones disintegrate at maturity about 6 months after pollination

It is not frost tender. It is in leaf 12-Jan It is in flower in April, and the seeds ripen from Sep 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 Wind. It is popular as an ornamental landscaping tree and as a Christmas tree. It is sometimes known as concolor fir.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay and nutritionally poor soils. Suitable pH: acid and neutral soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers dry or moist soil.

Cultivation:

Prefers a good moist but not water-logged soil. Grows well in heavy clay soils. Plants are very shade tolerant but growth is slower in dense shade. Intolerant of atmospheric pollution. Prefers slightly acid conditions down to a pH of about 5. Prefers growing on a north-facing slope. Trees succeed on poor dry sites in the wild. Trees are shallow rooted and therefore liable to be wind-blown in exposed sites. Trees grow almost as well in S. Britain as they do in cooler areas of the country. They are at their best in the Perthshire valleys of Scotland and in N.E. England, trees in the south and east of the country tend to be thin in the crown and soon lose their shape. Trees in the west grow better but also lose their shape after a while. New growth is from mid-May to July and trees are virtually never damaged by late frosts or aphis. Most trees of this species that are grown in Britain are in fact the sub-species A. concolor lowiana. (Gordon.)Lemmon. This form tends to grow better in Britain than the type. There are 2 basic forms of this sub-species, those from the north of the range are vigorous in height growth whilst the southern form is vigorous in girth growth. They both have a potential for forestry use in Britain. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm in height. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. A very ornamental tree. The crushed leaves have a strong lemony scent. Special Features:Attractive foliage, North American native, Fragrant foliage, There are no flowers or blooms.

Propagation :
Seed – sow early February in a greenhouse or outdoors in March. Germination is often poor, usually taking about 6 – 8 weeks. Stratification is said to produce a more even germination so it is probably best to sow the seed in a cold frame as soon as it is ripe in the autumn. The seed remains viable for up to 5 years if it is well stored. When large enough to handle, prick the seedlings out into individual pots and grow them on for at least their first winter in pots. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Alternatively, if you have sufficient seed, it is possible to sow in an outdoor seedbed. One report says that it is best to grow the seedlings on in the shade at a density of about 550 plants per square metre whilst another report says that they are best grown on in a sunny position.
Medicinal Uses:
The pitch from the trunk has been used as an antiseptic poultice for cuts, wounds etc. An infusion of the pitch, or the bark, has been used in the treatment of TB. An infusion of the foliage has been used in a bath for relieving rheumatism. An infusion of the pitch and leaves has been used in the treatment of pulmonary complaints.

Other Uses: .

Landscape Uses:Christmas tree, Firewood, Pest tolerant, Screen, Specimen.
A tan coloured dye can be obtained from the bark. Wood – very light, not strong, coarse grained, soft, not durable. Used mainly for pulp, cases etc. It is sometimes used in framing small houses but is not strong enough to be used in larger buildings. The wood lacks a distinctive odour and so does not impart a flavour to items stored in it. Thus it can be used for making tubs for storing food.

Picea abies

Botanical Name: Picea abies
Family: Pinaceae
Genus: Picea
Species: P. abies
Kingdom: Plantae
Division: Pinophyta
Class: Pinopsida
Order: Pinales

Synonyms: P. excelsa, Abies picea, Pinus abies

Common Names: Norway spruce

Habitat :Picea abies is native to Northern, Central and Eastern Europe. It is suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in nutritionally poor soil. Suitable pH: acid and neutral soils and can grow in very acid soils. It cannot grow in the shade. It prefers moist or wet soil. The plant can tolerate maritime exposure.
Description:
Picea abies is a large, fast-growing evergreen coniferous tree growing 35–55 m (115–180 ft) tall and with a trunk diameter of 1 to 1.5 m. It can grow fast when young, up to 1 m (3 ft) per year for the first 25 years under good conditions, but becomes slower once over 20 m (66 ft) tall.[4] The shoots are orange-brown and glabrous (hairless). The leaves are needle-like, 12–24 mm long, quadrangular in cross-section (not flattened), and dark green on all four sides with inconspicuous stomatal lines. The cones are 9–17 cm long (the longest of any spruce), and have bluntly to sharply triangular-pointed scale tips. They are green or reddish, maturing brown 5–7 months after pollination. The seeds are black, 4–5 mm long, with a pale brown 15 mm wing.

The tallest measured Norway spruce, 62,26 m (204 ft) tall, grows near Ribnica na Pohorju, Slovenia
It is not frost tender. It is in leaf 12-Jan It is in flower from May to June, and the seeds ripen from Oct to November. Bloom Color is Pink and the form is like pyramid. 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 Wind.It is noted for attracting wildlife. It cannot tolerate atmospheric pollution.

Cultivation:
Landscape Uses:Firewood, Screen, Specimen. Likes abundant moisture at the roots, if grown in drier areas it must be given a deep moist soil.Succeeds in most soils including those that are wet cold and shallow, but it is not very wind-firm in shallow soils. Intolerant of chalky or poor acid soils. Tolerates poor peaty soils. Prefers a pH between 4 to 6. Dislikes shade[200] according to one report whilst another says that it is moderately shade tolerant. Intolerant of atmospheric pollution. Resists wind exposure to some degree and is tolerant of saline winds. A very cold-hardy tree when fully dormant, though the young shoots are subject to injury by late frosts, though less so than P. sitchensis. A fast growing tree, it is widely planted in cool temperate zones for its wood. Young trees often grow 1 metre or more a year and can sustain an average of 60cm for at least the first 60 years though growth tails off as they grow older. Probably not that long-lived in Britain, about 200 years seems the absolute maximum. In some upland areas, especially over granitic or other base-poor soils, growth rate and health have been seriously affected by aluminium poisoning induced by ‘acid rain’ pollution. There are many named varieties, almost all of them dwarf forms. A food plant for many caterpillars. A very aggressive tree, it is hostile to other trees. Susceptible to attacks by bark beetles so it should be kept away from more valuable trees. A biological control is being introduced (1983). This species is susceptible to honey fungus. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. The seed is shed in spring, the cones release their seed whilst they are still on the tree. The bruised leaves emit a delicious musky smell. Special Features: Not North American native, Inconspicuous flowers or blooms.

Propagation:
Seed – stratification will probably improve germination so sow fresh seed in the autumn in a cold frame if possible. Sow stored seed as early in the year as possible in a cold frame. A position in light shade is probably best. Seed should not be allowed to dry out and should be stored in a cool place. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. They can be planted out into their permanent positions in early summer of the following year, or be placed in an outdoor nursery bed for a year or so to increase in size. They might need protection from spring frosts. Cuttings of semi-ripe terminal shoots, 5 – 8cm long, August in a frame. Protect from frost. Forms roots in the spring. Cuttings of mature terminal shoots, 5 – 10cm long, September/October in a cold frame. Takes 12 months. Cuttings of soft to semi-ripe wood, early summer in a frame. Slow but sure.

Edible Uses:
Edible Parts: Flowers; Inner bark; Seed.

Young male catkins – raw or cooked. Used as a flavouring. Immature female cones – cooked. The central portion, when roasted, is sweet and syrupy. Inner bark – dried, ground into a powder and used as a thickener in soups etc or added to cereals when making bread. An emergency food, used when all else fails. Seed – raw. Rich in oil and with a pleasant slightly resinous flavour, but too small and fiddly to be worthwhile unless you are desperate. A refreshing tea, rich in vitamin C, can be made from the young shoot tips. These tips are also used in making spruce beer
Medicinal Uses:
The buds, leaves and resin are antibiotic, antiseptic, balsamic, expectorant, sedative. A pitch, or resin, obtained from the trunk is rubefacient and stimulant. It is used externally in plasters etc for its healing and antiseptic properties. A poultice of the sap or gum has been used in the treatment of boil and abscess pain.

Other Uses:
The tree is a source of pitch (Burgundy pitch) and turpentine (Jura turpentine). Burgundy pitch is used as a varnish and in medicinal plasters. It is a strong adhesive. The turpentine is a waterproofer and wood preservative. They are obtained by incisions in the trunk, the resin is scraped out some months later. An essential oil from the leaves is used in perfumery. The seed contains 30% of a fatty oil, this is used in the production of a varnish. The bark contains some tannin. Both the bark and bark extract have been widely used in Europe as a source of tannin, the bark containing up to 13% tannin. Yields of tannin have been doubled by heating or steaming the bark as soon as possible after the tree has been felled. A fairly wind resistant tree and fast growing, it can be planted in shelterbelts to provide protection from the wind. The dwarf cultivar ‘Inversa’ can be grown as a ground cover plant in a sunny position. The cultivars ‘Reflexa’ and ‘Procumbens’ can also be used. They are best spaced about 1 metre apart each way. Wood – medium hard, fairly elastic, durable under water, light in weight and colour. Used for general carpentry, joinery, musical instruments etc. Valued for its use in the pulp industry to make paper.
