Origin of the name of the tree
Vladimir Dal believes that the name of the tree comes from the word “clear” (light). He explains this by saying that the crown of the tree is quite sparse, the branches are sparse and a lot of sunlight passes through the foliage.
Fraxinus (the scientific name of the tree) is translated from Latin as spear. Most likely, the plant received this name because of the shape of the leaves, thin and pointed at the end.
Description of the tree
Ash is a fast-growing deciduous tree of the Olive family. The height of the crop reaches 30 m. In nature, there are individual specimens from 40 to 60 m, growing in the southern regions.
The structure of culture
The crown is light, wide, rounded. The branches are sparse, thick, gray or gray-green in color, directed upward. The buds are black, without shine, with short hairs, rarely light brown. The apical buds are larger in size than the lateral ones. The bark is smooth, ashen with a gray tint. Mature trees have deep, narrow cracks. The trunk is cylindrical with a diameter of up to 1 m.
The leaves are complex and bloom late. The general petiole is pubescent, consists of 7-9 pointed leaves, which are arranged in pairs, opposite each other. The leaf blade has jagged edges, is smooth on top, dark green in color, fleecy underneath, painted in a light green tone. The leaves grow sparsely, so a lot of light enters through the openwork crown.
Flowers and fruits
The flowers of the tree have an unusual structure. In April - early May, red-brown or light purple bunch-shaped panicles with red stamens form on leafless branches. At the same time, growth buds begin to bloom. The flowers have no perianth, and the colorful tufts are odorless.
The fruits are drooping, winged green achenes up to 4.5 cm in length, then turn brown. Ash lionfish are oblong, with a curved wing, collected in clusters of several pieces. The nut is wide, flat, and occupies almost half of the lionfish. Ripens in August. The fruits develop in November.
Ash looks especially attractive in winter. After the leaves fall, the lionfish remain and can survive on the branches throughout the cold months, decorating the leafless tree with luxurious “earrings.”
Where does ash grow?
There are more than 50 species of this tree, but the most common is common ash.
The culture is found almost everywhere, lives for more than 250 years, and retains its growth capacity for up to 74 years. The spreading beauty is often used as an ornamental plant in park art. The tree is planted along alleys, small squares, and in front gardens. Ash can grow on any soil, is light-loving, and can withstand short-term flooding. Rarely forms pure plantings, often adjacent to alder. Grows well in soils rich in calcium. It easily tolerates drought, but in the absence of moisture it begins to dry out. Young plants have a bush-like shape. Representatives of the genus are widespread in mixed and deciduous forests. Sometimes ash trees occupy small areas in dry, shallow ravines and ravines.
Growing
Agricultural technology
It is highly winter-hardy and drought-resistant (excellent), quite resistant to diseases and pests (good), but in some years the leaves are damaged by ash blight, and the trunks and branches are damaged by the small ash beetle. Every year, common ash blooms in late April - early May, bears fruit well, and produces abundant self-sowing (excellent). Light-loving, grows well in moist, fertile soils, but tolerates poor and dry soils. Grows quickly, dust and gas resistant.
Reproduction
The plant reproduces by seeds .
Varieties
Nana
Crown foliage
Ash is easily recognized by its distinctive large leaves. They grow up to 40 cm in length and are composed of 7-15 opposite elements. The length of each is from 4 to 9 cm. They are wedge-shaped with a pointed apex. In the center of the ash leaves (photo below) a vein is clearly visible; from the bottom of the leaf it protrudes as a whitish vein. The stalk has a grooved and semicircular shape.
The leaves appear quite late in the spring, and in the fall the tree often sheds them while still green from the first autumn frosts. If the autumn of the year is mild, then the leaves acquire a beautiful bright yellow color.
Types of ash
Ash is the most numerous and popular species of the Olive family. There are more than 50 species, mostly deciduous trees, but there are varieties in the form of shrubs.
Ordinary
Common or tall ash (Fraxinus excelsior) reaches considerable sizes. There are quite massive samples - 40 m. The bark is colored gray-green, which with age becomes ashen in color and becomes covered with cracks.
From the buds, odd-pinnate leaves of light green color are formed. Snow-white inflorescences appear in early spring before foliage. After flowering, fruits are formed - lionfish, reaching a length of up to 5 cm. The fruits have a light olive color, turn brown and begin to ripen in the fall. They can stay on the shoots all winter.
European countries and Transcaucasia are considered the homeland of high ash. Grows on fertile, slightly alkaline soil. In the southern regions of Russia, ash is grown as an ornamental plant to decorate a personal plot.
Common ash has a high and openwork crown
Pennsylvanian
Pennsylvania ash, or downy ash, grows up to 25 m in height. Young branches are felty and covered with dark brown bark. The leaf blade is imparipinnate, consists of 9 leaves of a dark olive color, which by autumn do not change their color and turn green. The inflorescences are pale green, without aroma.
The species is fast growing, gaining about 50 cm in height and 30 cm in width per year. Lives up to 350 years. Ash grows in fertile soil and a sunny place. Although the variety is frost-resistant, it is not recommended to grow it in the northern regions.
The plant prefers moisture and therefore needs regular watering.
Manchurian
As you can easily guess from the name, this species came to our country from Manchuria, China, Japan and Korea. Grows in forests, on nutritious soil, next to Japanese elm and Maksimovich poplar. The centenarian grows up to 350 years.
The tree is dioecious and when flowering is covered with flowers of different sexes. The variety has an erect trunk, from which the branches diverge obliquely. It reaches a height of up to 35 m, and a diameter of up to 15 m.
Manchurian ash has a specific shape and type of leaf
The bark is brown or ash-colored and has small cracks and longitudinal ribs up to 5 cm thick. Flowering begins in May and continues until September. In place of flowers, fruits appear - lionfish, which last until spring. At the ripening stage they are olive-colored.
Flat lionfish acquire a brown tint towards the end of ripening
Chinese
Chinese ash, or ailanthus, is a light-loving palm-shaped plant native to Northern China. It grows throughout Russia and is widely used for landscaping populated areas. The trunk is gray-brown in color with a furrowed structure of thin bark. The leaves are large, very similar to palm trees, reaching a length of up to 60 cm. Yellow-green flowers are collected in large panicle inflorescences. Flowering begins in mid-summer. After the flowers, small red-brown fruits are formed, which stand out against the background of olive foliage.
Ash flowers emit a not entirely pleasant aroma
This type of ash is fast-growing; by the age of five years the tree reaches 5 m. Chinese ash, or the tree of the Gods, loves a lot of light and warmth. At a young age, the plant is not frost-resistant, but the frozen crown is well restored due to the rapid growth of young shoots. Thanks to its powerful roots, the plant can grow in an open, windy area.
In medicine, due to the rich chemical composition, leaves, bark, flowers and fruits are used. Fresh bark treats dysentery, flowers and foliage treat scarlet fever and diphtheria, and the fruits are prescribed for diseases of the genitourinary system. The leaves have antiviral and antimicrobial properties. The leaves are used to make decoctions that are taken to treat fever.
The bark and leaves have irritating properties; when collecting raw materials, a pustular or blistering rash may appear.
Chinese ash is unpretentious to grow and grows well in moist loamy soil.
All types of ash are smoke and gas resistant, do not tolerate pruning well, grow quickly, and reproduce by sowing seeds.
Types of ash:
American Ash / Fraxinus americana American ash grows in eastern North America. In deciduous forests on deep, rich, moist, well-drained soils near watercourses and on the slopes of hills and mountains, up to 1050 m above sea level. seas. American ash is a powerful tree, up to 35 m high, with a broadly ovate crown, bare young shoots and light brown buds. The leaves of the plant are compound, odd-pinnate, of 7 (5-9) leaflets, ovate, entire or serrated, glabrous, dark green above, glaucous below, up to 12 cm long. | American ash |
American ash grows quickly, is relatively drought-resistant and more frost-resistant than common ash, and is not damaged by spring frosts, since the buds bloom 8-10 days later than other ash trees. American ash tolerates city conditions well and is durable. Propagated by sowing stratified seeds. Thanks to its fast growth, beautiful openwork crown and durability, it is a valuable plant for alley, group and composition plantings. In culture since 1874.
American ash has several decorative forms: - white-edged; - pointed - with entire-edged leaves, with a pointed apex, dark green above, shiny, below - bright gray, bare; - red-fruited - with a very impressive red coloring of the fruits; - nut-leaved - with less shiny leaves than the typical form, wider and pubescent below.
White Ash / Fraxinus ornus White ash, or as it is also called, flower ash, is common in the European part of Russia, the Middle East, and Western Europe. White ash is a tree up to 12 m high, with a regular, round, dense crown. The leaves are light green, consisting of 7 oblong-ovate, irregularly toothed leaflets up to 9 cm long, pubescent below along the midrib. It differs from other species of the genus in its white, fragrant flowers, with long, narrow petals, collected at the ends of the shoots into lush, dense panicles up to 15 cm long. During flowering, which lasts 7-10 days, it is very decorative. | White ash |
White ash is characterized by great light tolerance and drought resistance. It grows relatively slowly. Not frost-resistant enough. Recommended for single, group and alley plantings in the south of Russia. In culture before 1700.
White ash grows from late April-early May to early October. In the first 3 years the growth rate is average. Doesn't bloom. The tree's winter hardiness is low.
White ash has a number of decorative forms: - nut-leaved; - narrow-leaved; - round-leaved.
Lanceolate Ash / Fraxinus lanceolata Lanceolate ash, or as it is also called green ash, is found naturally in the eastern part of North America. Distributed in deciduous forests (sometimes forming pure stands), along the banks of watercourses, and on damp hills. Lanceolate ash is very decorative with a slender trunk, compact crown and shiny, dark green leaves, pale green below. Lanceolate ash grows up to 15 m in height. It is distinguished by fairly fast growth and high drought resistance. Less demanding on soil than other species, more stable in urban environments. | Ash lanceolate |
Lanceolate ash grows from late April-early May to mid-October. At a young age it grows quickly. Blooms in the first half of May, 7-8 days. It bears fruit from the age of 7, annually, abundantly, the fruits ripen in September. Winter hardiness is high. Seed viability is 90%.
Lanceolate ash is often mistakenly called American ash, confused with Pennsylvania ash, from which it differs in the size and shape of its fruits and a number of other morphological characteristics. This type of ash deserves the widest use in landscape gardening construction in cities in the forest, forest-steppe and steppe zones of Russia.
Common ash / Fraxinus excelsio Common ash is widespread in the European part of Russia, in the forests of the mountainous Crimea and the Caucasus, throughout Western Europe, in the Mediterranean and Asia Minor. Available in many nature reserves. In deciduous forests on fertile carbonate soils, light-loving mesophyte. Common ash is the most famous representative of the genus. Tree up to 30 m tall, with a broadly oval, openwork crown, with straight, slightly branched branches and odd-pinnate foliage. The trunk bark is initially ash-gray, almost smooth, later with deep, longitudinal and small transverse cracks. Young shoots are bare, greenish-gray. The buds are black with velvety pubescence, very impressive against the background of bare branches. | Common ash |
The leaves are imparipinnate, of 7-9 sessile, broadly lanceolate, serrate along the edge, with bright green leaflets above, green below, hairy along the veins. Flowers without perianth, inconspicuous. The fruits are lionfish, up to 5 cm long, often stored on the branches all winter.
Common ash grows quickly and is photophilous. In adulthood, it tolerates temperatures down to -40°C. In harsh winters, some of the shoots may freeze, so it is better to plant it in protected places. It also suffers from late spring frosts, but then quickly recovers. It tolerates air dryness well, but worse tolerates soil dryness. It is demanding on soil and is not sufficiently smoke and gas resistant. It is propagated by seeds, which germinate without stratification only in the second year. Decorative forms are propagated by grafting onto the main species. Lives up to 300 years.
Common ash is a valuable tree for green building due to its fast growth, powerful size, slender trunk and openwork crown. Looks good in alley plantings, complex compositions, and road lining.
Common ash has many forms used in landscape gardening. The most interesting of them are the following: monumental (f. monumentalise - very impressive, strong growth, with a pyramidal crown; - low - slow-growing, with a compact spherical crown; - weeping - a tree up to 8 m tall, with a dome-shaped crown and long branches hanging down to earth, very impressive in a single planting; - horizontal - with horizontally spread main branches, a wide, flat crown and weeping branches; - curly - with small, curly, dark green leaves; - finely cut - with very narrow, slightly jagged leaves; - variegated - a large tree with simple, single or partly trifoliate leaves, looks very unique when planted alone; - yellow-leaved - with yellow leaves; - golden - with yellow shoots and smaller leaves; - golden - variegated; - golden weeping; - silvery variegated; - variegated - on young shoots the bark has pink and white stripes, which greatly decorate the tree in a leafless state.
The forms are used in single and group planting in the foreground.
Downy Ash / Fraxinus pubescens Downy ash, or as it is also called Pennsylvania ash, is the most widespread in the nature of North America, where it grows along river banks and on floodplains. Fluffy ash is a tree growing up to 20 m in height. A free-growing tree has a spreading, irregularly shaped crown. Shoots with felt pubescence, brownish-brown.

Decorative configurations
Let's take a look at its decorative counterparts. Quite often they are used in landscape design.
There are several types:
- monumental, its crown has a pyramidal shape;
- low, its crown is round, ordinary, of small size, growth rate is slow;
- weeping, the branches are long, hanging down to the ground, the crown is dome-shaped, the height can reach about 8 meters.
The wood has a very beautiful texture, its core is dark, but there is a light shade on top. In density and strength it is very similar to oak bark.
Ash
Ash wood, which has medium density, belongs to the heavy and hard varieties of wood. It has high elasticity, wear resistance and toughness. Surface treatment is quite easy and is perfectly impregnated with stains. This material is not resistant enough to the external environment and quickly deteriorates upon contact with the ground.
Ash is used both in the form of solid wood and in the form of plywood or veneer, for example, for the manufacture of kitchen and bedroom sets, as well as other furniture. Widely used as coatings for walls and ceilings, in the production of parquet and floorboards.
Ash boards have high flexibility and strength compared to other species. Therefore, bent shapes for chairs and armchairs are made from this material. The high wear resistance of edged ash boards allows them to be widely used in a variety of construction and manufacturing sectors. Ash edged boards are capable of excellent heat conduction, unlike, for example, pine.
Furniture made from ash has a very beautiful yellowish or pinkish tint, depending on the area of origin of the material. Your room or living room will take on new shades of color if you decorate it with ash furniture, which perfectly reflects sunlight. Furniture made from ash will add comfort and coziness to your home, because no other material can compare with natural wood.
Solid ash parquet boards are characterized by excellent strength properties. This material has an attractive texture and color and, importantly, is resistant to deformation.
Areas of application of ash
Less beautiful wood species and plywood are finished with veneer made from ash wood and its roots. Ash wood has high impact strength, bends well (especially sapwood parts), does not produce flakes, and is therefore widely used in the manufacture of sports equipment.
In a number of European countries, ash bark, buds, leaves, and flowers are used as medicinal raw materials. The dried juice called "manna", which is secreted by the ash flower, or manna, is included in the pharmacopoeias of some Western European countries.
Ash is a technical species, and the bark, wood, roots, and leaves of this tree are in demand in industry. Blue, black and brown paints are made from the bark and leaves and used as a tanning agent; Fresh and dry leaves serve as good feed for livestock.
In England, unripe fruits are collected and immediately pickled (in vinegar with pepper and salt). They are served as a spicy seasoning for vegetable and meat dishes instead of capers. In the Caucasus, unripe fruits are pickled in a similar way and used in food as a hot spice. Young green seeds after salting have the taste of pickled walnuts. They are used as a spicy seasoning for appetizers, first and second courses.
Ash wood, which has high physical and mechanical properties, is widely used. It is used to make veneer, bent and carved furniture, cut light aircraft propellers, railings and parquet, body sides, trim, window frames and carriage sofas, some parts of looms, butts and stocks of firearms, hunting and combat bows, sports equipment - skis, tennis rackets, baseball bats, hockey sticks, billiard cues, oars. Beekeepers made fairly capacious hives from the bark of large ash trees.
Since ancient times, strong clamp pliers and axes have been cut out of ash stumps. But strength is not the only advantage of root wood. Artists and sculptors are more attracted by the variegated layering and silkiness of twisted fibers, which form a very beautiful texture. The wood of ash root looks like the wood of an olive tree. It sands well, polishes and paints evenly. Having uprooted the ash stump, wash the roots and saw it into pieces. If the tree was recently cut down, then the roots are debarked and, having covered the ends with lime, they are dried in piles in the air under a canopy.

What does ash look like?
The description of the tree goes something like this:
- It is a deciduous tree twenty-five to thirty-five meters high;
- It has oblong, pointed leaves that are dark green in color;
- The leaves grow quite sparsely, so the sky shines through the crown beautifully. It is because of this arrangement of leaves that it got its name. The name “ash” comes from the word “clear” , because through the openwork sparse crown, consisting of graceful leaves, the sky is clearly visible;
- The fruits are lionfish, reminiscent of maple fruits. Each fruit contains seeds inside.
The spreading beauty is actively used in landscape design . This tree looks beautiful both in winter and summer. The lacy foliage creates light shade, and in the fall its spiky leaves turn vibrant colors. It, along with the birch tree, is one of the symbols of Russia. Seedlings for planting in a summer cottage can be purchased at nurseries. Of course, you can try to grow it from seeds, but this is quite a troublesome task. The seedling will develop much faster; the main thing is to create favorable conditions for it. Recently, many summer residents have been planting ash simply because this tree looks very beautiful.
Ash bark and leaves: use in folk medicine
The leaves of the tree have been used in folk medicine for centuries. A variety of decoctions and infusions are prepared from the dried leaves for internal use. You can use medicinal raw materials from dried leaves separately or as part of herbal preparations. The bark of the tree also has medicinal properties, our ancestors also knew about this from ancient times. Medicinal raw materials from dry leaves and crushed bark are used in the following cases:
- In the treatment of obsessive dry cough;
- For diseases of the musculoskeletal system, for joint pain caused by arthritis, arthrosis, rheumatism;
- In the treatment of cardiovascular diseases;

People sincerely believed that these miraculous talismans would help them sail safely to a distant land. One of the legends of the indigenous people of America, the Indians, tells that once upon a time there were no people or animals on earth, but only water. The bird brought a piece of earth and built a nest on the water, and then a small island appeared from this nest. A large ash tree grew on the island.

In ancient legends you can find myths about the involvement of ash in the appearance of people on Earth. The Scandinavian gods - Odin, Vili and Ve - created a man from ash and a woman from alder.
