If you did not recognize it on the first photo, you can not immediately guess, about which there is a speech in this dendrological riddle. This is how you can check out a good specialist in the field of the knowledge of the trees. I confess, I in my time I failed this test task.

And the speech today will go about alder. When I was informed, I first thought: why is she not beautiful, why and gray, and green (I knew about the black for a long time)? So, then I looked at the fall and understood: Olhi, there are no autumn colored leaves, there is no colorful leaffall. The picture is rather gloomy: more green and stuffing leaves with sad bedspreads lie on the ground. Even the ancient Greeks described alder as a sorrowful tree.

We (Russians, Ukrainians, Belarusians) in oral creativity Olhu did not notice in any way - neither good, like birch, Ryabin, Oak, nor bad as Osin. But here in Slavic magic, alder is considered to be a faith. According to beliefs, if you stick the branches along the edge of the field, then degrees will not fall on it, and in the clothes of newlyweds it will be protected from damage. Water from the roots of Olhi was considered protected from the disease.
The ancient Scandinavians believed that from alder made a woman, and a man is out of ash, like a more durable tree. Druids Olha refers to the period on March 18 - April 14.

And now let's forget this sad autumn impression and prejudices of the ancestors, and try to figure out whether Olkh needs to be needed in the country as we practical people, and most importantly - why?

We, in the Carpathia, are growing both types of alder, which was stated in the riddle, and another one, which is not said. They belong to the birch family ( Betulaceae.Gray).

Alder Black (sticky)



For alder black (Alnus Glutinosa (L.) Gaertn.) It is characterized by an opposite leaf (a narrower end of a sheet of cutting), sometimes with a removal from above, a dark fractured bark. Young shoots and kidneys sticky, which gave the second name-synonym for this plant - alder sticky. It is high, up to 35 m Tree, moisture, demanding to the wealth of the substrate and its moisture. Root offspring does not give. It should be noted that Olha black swamps does not grow, she needs areas at least with some running water.

The most interesting forms of alder black: 'aurea', 'pyramidalis', 'imperialis', 'laciniata', 'imperialis', 'incisa', 'quercifolia', 'sorbifolia'.

Olhi gray (Alnus Incana (L.) Moench.) Cora, according to the name, light gray, and the back of the leaf and young shoots are white-pubescent. The leaf on the top is pointed, which gives this alder similarity with birch. The crown shape is always very attractive, egg-shaped. It is worth noting that the tree is less large-scale than an alder black - only 20 m, gives root offspring.

Its decorative forms are known: 'Laciniata', 'Pendula', 'Pinnatifida'.

Alder Green

This Alpine view of Alder Alnus Viridis (Chaix.) D.C. (Synonym Duschekia Viridis Opiz) - Quite interesting, perhaps, many tourists do not pay attention to him, admiring the beauties of the Carpathians. This is a low flutter shrub, with gray bark and oval sheets. Nevertheless, this kind of alder has interesting properties, one of which is shadowlessness. And this alder is frost-resistant, undemanding to the wealth of the substrate, rather rapidly growing. If you need to quickly fasten the slope on the site, try it for it, especially in a zero-shaded place. Surprisingly, I was watching her sheep eating her.



Yes, biologists forgue me, but more often daccias are dealing with a row black and gray. And in Siberia and in the Far East of Russia, you can meet Olhu Siberian ( Alnus.sibirica.), Olhu fluffy ( Alnus. Hirsuta.), Olhu Japanese ( Alnus. Japonica.) And other parents of this kind. Well, if you remember that the kinds of alder can form interspecific hybrids, then even the scientific men will take the head.

I would like to immediately note the main "useful" property of the types of alder - the presence of nitrogen intimidating bacteria in its surface root system. That is, nitrogen accumulates under the roots of azot, and is environmentally friendly.

And the negative property of alder is to reset the leaves with green - with more than compensated by their property to quickly decompose, improve the structure of the upper layers of the soil. And one more refinement for those who want to make the shape of alder on the site are less persistent, so do not put them in "extreme conditions".

I think it is worth mentioning about a certain shortage of decorative forms in nurseries. Some owners, managers, want to see only beautiful, winning outwardly, as well as fruit plants. Olha does not apply to them. Therefore, even specialists may have problems search for plants for areas with a winged substrate. I recently needed to find Saplings of Alder Green - it did not work! If someone wants to purchase other species is simpler, and even more affordable than you can imagine. So, the gray olhu can be multiplied by the siblings (this property has already been mentioned), and Olhu black, green and other species can be multiplied by seeds or dig a sighter in nature. Olhi seeds rose and scattered a year after flowering - in April-May. Alder black can be multiplied with cuttings, but whether it is possible to mess if you can get a whole forest with a special name - Olsanik, Olshovnik, Olsnyak - call as much more like!

Alder is a widespread deciduous tree or shrub from the birch family. The greatest population is concentrated in a moderate climatic belt of the northern hemisphere. Separate species are also found in South America and Asia. Olha grows in mixed deciduous forests on wet, well-haired soils. Prefers the neighborhood with oak and beech. The scientific name of the Alnus plant is translated - "At the shore". It is not surprising that most plants are found on the shore of fresh reservoirs and rivers. In the people, the tree also magnifies the "Valkal", "Slimnik", "Olekh", "Elshina". Olha is famous for its wood and therapeutic properties. It looks great on the plot, is used in traditional medicine and woodworking industry.

Plant Description

Alder is a long-term leafy shrub or a tree with a developed, but superficial root. Because of this, large varieties often valit the wind. On the roots over time, small bloats are formed, filled with nitrogen-fixing bacteria. Recycling nitrogen from the atmosphere, Olha sat down very effectively and enriches the soil. The shoots have a rounded cross section and are covered with a smooth grayish-buoy bark. In places of appearance of new branches, horizontal wrinkles are formed. On the crust of young shoots, triangular or heart-shaped lentils are noticeable.

Olhi leaves oval or reverseless, with a wide rounded end and gear or wavy edges. The surface of the sheet is smooth, wrinkled between the veins. The foliage grows next to short stiffs. Highlights fall early.

At the end of the spring, one-sex flowers bloom on Olkom. Stagging concentrated at the ends of young shoots in long flexible inflorescences (serges). They are painted in a red-brown or yellow-brown tint. Earrings with pesting colors are shorter and dense ears at the bottom of the escape. Blossom starts along with the blooming of the leaves.















Pollination occurs with the help of wind. After it, fruits are ripening - miniature bumps with decorated flakes. Maturation is completed by the middle of the autumn. Inside each nuts there is a single hack with wings (less often without them). Mature sash is revealed and seeds are hurt. The release process can delay until spring. The wind spreads seeds for quite long distances, and spring streams complete the migration process by many kilometers from the parent plant.

Views of Olhi

Today, there are 29 species of plants to the family of Olhi. However, united opinions, scientists cannot yet come, since the plant itself is inclined to modify and hybridization, therefore, part of the species belong to the hybrid varieties of others.

The plant lives in the moderate climate of Western Asia, North Africa and throughout Europe. It is a wood up to 35 m in height, often with several barrels with a diameter of up to 90 cm. Perpendicular to the branch barrel form a dense pyramidal crown with a diameter of about 12 m. The maximum growth rate is achieved at the age of 5-10 years. The life cycle is 80-100 years old. Single copies live up to 3 centuries. The developed rhizome is located in the upper layers of the soil and covered with the tubers. The leaves have an almost rounded shape with cigarette housing. Their length is 6-9 cm, and the width is 6-7 cm. Early spring at the ends of the branches are blooming earrings 4-7 cm long. They have a yellowish brown color. Pestical servants are almost black, they grow on an elongated flexible leg and make up 1.2-2 cm long with a width of up to 1 cm. Fruits in length do not exceed 3 mm. In the autumn, their flattened laid surface becomes wrinkled, reddish-drone.

Very decorative and beautiful wood up to 20 m in height. Its barrel and branches are covered with almost smooth light gray bark, and young sprouts are dark red. First, the green booster is denomated, and then it becomes naked. Egg-shaped dark green leaves have a pointed edge and gear sides. On the back side, the sheet plate is covered with reddish veins. Stagging inflorescences are cast red-brown. Egg-shaped bumps grow to 15-25 mm.

An unpretentious spreading shrub or a tree to 20 m in height has a narrow egg-shaped crown. The cylindrical curvatured trunk in width reaches 50 cm. It is clearly visible longitudinal grows and depressions. A variety at an early age grows very quickly. Rhizome is located at a depth of 20 cm. The bark is dark gray, not sticky. Oval or lancing leaves from above have a smooth leathery surface, and on the turn of thickly covered with a silver pile. Their length is 4-10 cm, and the width is 3-7 cm. Blossom occurs at the beginning of spring, until the leaf is dissolved.

Olhi wood

Alder is actively used in woodworking and furniture industry. And although the plant wood does not differ high density and durability, it is popular for the ease, resistance to rotting and exposure to water. With low cost, wood is pretty light. She behaves well with drying (not curved and does not crack). The advantage is the homogeneous coloring of the nucleus and the crook.

From alder make parts for wells, ships, interior decorations. It is with her who love to work carvers for wood. Also from this tree produce coils for threads and other small products.

Firewood from alder is burning without an extra soot and exuded a pleasant smell. This is the best material for bath or cooking.

Methods of breeding

Olhu multiply seeds, cuttings and roasting pigs. The most common seed method and especially self-sowers. By autumn, the ripened bumps begin to reveal and free the seeds. During November-March, they fall into the ground and pass natural stratification. After that, during the melting period, the seeds are drinking moisture and cry. When landing, the seeds close up in the worst soil at a depth of 2.5-3 cm. In the first year, only a small sprout is formed and the rhizome will develop. Gradually, seedlings become stronger and quite quickly turn into a lush bush or a small tree. Every year it will add a height of 50-100 cm.

Often, young sprouts appear from the trunk. In just a year, their height can reach 1-1.5 m. Spring is killed and transplant to a new place. It is recommended to maintain a commercial land on the roots and not allow him to dispel.

In the spring and summer of young shoots, cuttings are cut with a length of 12-16 cm. They are rooted immediately in the open soil. The best survival rate is shown by plants treated with the root formation stimulator. Cuttings need to spread regularly. By the autumn plants, the roots will be allowed and enough to grow for wintering without shelter.

Landing and care rules

Olha is very unpretentious to the location and the composition of the soil. She grows well in a half and outdoor sun, on gummed loam and poor sandy soils. Due to its ability to enrich the land with nitrogen, Olha itself will create a nutritious layer for himself and other representatives of the flora. The exception is alder black, which normally grow can only on nutritious and wet land. It is suitable for refining and strengthening the coastal zone or beam, where the groundwater is close to the surface.

For landing, it is recommended to use the soil with a neutral or slightly alkaline reaction. In the ground, lime, humid and fertilizer ("Kemira") are preliminary. The landing is better to spend during the growing season. On the bottom of the landing pits lay a layer of drainage material (sand, rubble). Then we spread the roots and fall asleep free space of a fertilous soil. The root neck must be in the surface. The earth is abundantly watered and tamped, and the surface is mounted with a layer of crushed straw, peat or chips.

Further care is practically not needed. In the year of planting plants, it is necessary to water more often, while not allowing water stagnation in the upper layers of soil. For better aeration, the roots of the earth are regularly loose and weeds remove. It is not necessary to clean the tool too deep to damage the roots.

Also in the first year, it is necessary to feed plants by compost or organic fertilizers. From next year, the need for this procedure will disappear.

In anticipation of wintering, no special events do not need to spend, as Olha has a high winter hardiness. She is not terrible even harsh and misunderstanding winters.

Medical properties

Olhu can be called useful and even a healing plant, which has great benefits to human health. In cones, leaves, crust and roots contain tannins, flavonoids, minerals and vitamins. From the drug raw materials, alcohol and water infusions, as well as decoctions, are made of alder black or gray. Preparations help with colds, bronchitis, irritation and glands on the skin, inflammation of the mucous membranes, bleeding. Olha has anti-inflammatory, binders, hemostatic, expectorant actions.

A decoction of cones drink with colitis, dysentery, diarrhea, bleeding from the gastrointestinal tract, nose and mouth. They are wicked by mouth with stomatitis and periodontitis. The root tincture is recommended to women to normalize the reproductive function and menstrual cycle, combating inflammation of the genital organs.

Usually drugs from alder do not have contraindications, with the exception of an allergic reaction. However, everything is needed in everything, abuse and exceed the recommended dosage is not recommended, since certain components have the property of accumulating in the body.

Use in landscape

Oval, Olhi openwork Croon with moving branches and tremble leaves looks very vivid. Plants do not suffer from urban air, so they can be planted along the road. As a living hedge, low trees or lush shrubs up to 3 m high are usually used. They are planted with a ribbon way quite thick and regularly attach the form.

Large one-tank trees are used in single landings or group on a large area. They are planted along the tracks and alleys. Also, alder can also be used in the compositions of shrubs and trees, combining plants with different color and structure of foliage.

The real harbinger of the offensive of spring, at first glance, seeming the most ordinary tree is alder. Tree photos transmit all the beauty of such beauty. Her slender barrel is covered with a smooth bark, rounded leaves for the season do not change their colors and remain green until the onset of frosts.

Alder tree: Description

The photo representative of the forest shows the wealth of her crown, although the latter seems rarefied due to the uneven, loose location of the branches. The flowering process begins early in the spring, when the snow is still lies; The role of the pollinator is performed by wind.

What does alder look like? The tree blooms with earrings separated by female and male, which in the process of ripening (September-October) acquire a red-brown color. Female have a length of about 1 cm, arranged by groups of up to 8 pieces and during the ripening period wept like cones.

Men's earrings on branches are assembled at 4-5 pieces, during flowering reach lengths 5-9 cm. Olhi leaflets begin to bloom after flowering, fruits are small green bumps. They may be outless, and may have a film or leathery porch. In winter, the bumps are closed, begin to open in March, releaseing the seeds in this way, the aging of which occurs at the end of the autumn. Olhi foliage contains a large amount of nitrogen - an important soil fertilizer.

Alder as part of a natural complex

100 years - the average age rate, and 150 years - the age of such a natural copy, like a tree of alder. Where does such an unlikely, but very useful tree grow? Olha prefers wet soils (these are the shores of streams, rivers and various reservoirs) and often forms thickets, so-called Olds: in pure form or mixed. In the north it is believed that alder is a coniferous tree, in the southern regions it forms with oak and beech mixed forests. The plant is well adjacent to birch, fir, oak, lime and aspen.

Alder is a valuable honey. From its kidneys and leaves are distinguished resinous substances that serve bees to produce propolis.

Dry leaves of the plant are perfectly suitable for feeding cattle.

Black alder - deciduous tree

Olha Black has the greatest distribution among famous varieties, which received its name for the black bark in an adult tree. In Greek mythology, black alder, characterized by sticky glittering leaflets, is associated with the festival of fire and the arrival of spring. Alder (photo of a tree is given in the article) loves light and moisture very much; Growing on moistened places can create olhovy fop. At the same time, it does not endure standing water.

The growth of black alder, who is considered a single due to non-acceptance of the trees of other breeds, is quite fast. The plant can reach 20 meters. Blossom begins in April, and the fruits (shishche with a narrow wing) are matured only at the end of the next spring.

Black (sticky) alder, more capricious against the background of other varieties, introduced into the Red Book of Moldova, Kazakhstan and some regions of Russia. This tree landslide parks and squares, thanks to the widely branched root system, it is planted along the water bodies, strengthening in this way of the shore.

Beauty with brown earrings

Alder - wood, a description of which allows you to highlight its main characteristics, is an equally popular view of the birch family. To the height of Alder Gray can reach up to 16 meters. Therefore, it is planted for fixing the ravines and the coastal part. Printed by siblings roots, cuttings and seeds.

What does alder look like? The tree has a gray, slightly curved barrel, gray leaves, brown earrings. These are the main signs for which Olhu can be distinguished among other plants. Frost resistance and ability to grow on depleted soils and wetlands - the advantages that is characterized by a tree of alder.

Description, photo of green beauty, an integral part of the natural complex, will allow you to get to know her closer.

Alder in decorative art

The growth is quite active, especially at a young age, during this period, most often, wild thickets are formed. Thanks to such characteristics as the uniform structure of wood, its softness, viscosity and fuel, alder is a tree that has been widespread in industry. Its wood for a long time is applied as the optimal material for artistic thread, is the basis for creating carved dishes, decorative panels and sculptures. With dry distillation from alder, coals are obtained, which artists use in their work, creating future masterpieces, and wood vinegar. Decorative value has influx in trunks.

Production application

Olha is easy to process, well planes, sawing, glued. Perfectly tolerate polishing, varnishing, filling; When screwing the screws does not split, when climbing, nails can be peeling. When drying wood, which is also used in the production of powder, does not change its properties: dries quickly, it does not breed and does not crack. Thanks to the qualities of olhu used in the manufacture of musical instruments and parts to them.

Olh wood is resistant to water, does not rot, therefore serves as a material in the production of bridges, rafts, underwater structures and supports. Metals critical refers to the gland and in places of clogging of iron nails will cause the reaction of their rusting and, as a result, the appearance of gray circles in places of contact. Does not like contact with cement mortar, which causes an alkaline reaction inside the tissue of the tree and its posting.

Alder - a tree that is widely used in the manufacture of plywood and chipboard. The chips from it is added as a binder antiseptic in the production of beech chips, spruce, spines.

Alder as building material

Alder tree is used in the construction of wooden houses, carved entry gates, well crates, production and restoration of furniture and decorative interior details. Smooth trunks are used as pillars for the fence.

This is an excellent material for the manufacture of packaging boxes, pallets, coils, various molds for casting. Olha, intended for external construction, requires mandatory antiseptic processing. Otherwise, the tree will start rotting, especially with close contact with the open soil.

In industrial production from wood, alder produce paper, waste is used as fuel. Olkhovy firewood is considered high-quality furnace fuel. With their help used to be burned out of the pipes excess sozh. Such firewood is perfectly lit and characterized by high heat transfer and a lack of fug. No wonder they are called "royal", because by them in ancient times, the royal chambers were heated.

The Black Olhi bark is a first-class material for obtaining dyes for wool and skin, gives red, black and yellow colors. Brown paint is made from the kidneys.

The use of alder in folk medicine

The useful properties of alder are widely used in medicine: the traditional and folk, using the most part of the cones, the leaves and the bark of the tree, which contains tubinous substances. Decorations and infants made of cones and bark are adopted as astringent, anti-inflammatory, disinfectant, antibacterial and hemostatic agent. An purulent wound will quickly heal if the leaf of the black alder tree is applied to it.

During constipation and hemorrhoids are used by vodka infusion of earrings; With diathesis and eczema, the decoction of flowers collected at the beginning of the flowering period. The decoction of coys of alder perfectly helps to normalize the natural intestinal microflora after taking antibiotics and is used in the treatment of diseases of the gastrointestinal tract. Such a means also helps well with inflammatory processes of nasopharynx and throat, colds, angins and pharyngitis.

In folk medicine, with nasal bleeding to the nose, it is recommended to lay fresh leaves of alder in the form of tampons. The decoction of them helps well for gout, arthritis, arthritis pain. For the preparation of dry baths, fresh, just the collected leaves of alder are heated in the sun or in the furnace and spread in a thick layer on the bed where the patient is put. They look all the body and covered with a warm blanket on top. The duration of such a session is about an hour. The best effect will be, if the leaves are placed in deep tub, and when they warm up, it is necessary to plant the patient there. In the same way, it is treated with birch leaves.

Brooms from alder, well cleansing, disinfecting, tonic skin and giving strength and vigorous, are very popular with bath procedures.

Alder in veterinary medicine

In a number of countries, fresh okhovy leaves are used to combat fleas in pets. They are scattered on the floor. The concentrated decoction of the leaves was not so long ago when combating clusters - for the processing of walls and washing the beds. The bumps were given pet with blood diarrhea.

Due to the content of vitamin C, carotene and proteins, black alder leaves widely use traditional medicine. From the cones, dry extract is made - hmelin, used in disease with dysentery; From wood - Activated coal tablets.

In cooking for smoking meat and fish, sawdust and firewood are used.

The collection of cones begins at the end of autumn and continues until March. For this, the ends of the branches on which the bumps grow are neatly cut off by the secateur, after which the latter break. Fallen nollodies are not suitable for use. The collected raw material, laid out with a flat layer, dried under a canopy or in attics in a ventilated room. In warm weather, the cones are dried outdoors, periodically stirring. The shelf life of the nozzles is 3 years.

Every year, with the arrival of spring, many garden plants are in a hurry to report on the approach of heat. Excellent tip Gardening and flowers gives a olha. It is in the springtime that the plant becomes especially attractive. Its rounded sheets and lush crown do not lose their green colors up to frosts.

general information

The description of alder (OLHA) involves a pretty thick crown, but due to the uneven location of the branches, it looks slightly sparse. When snow still lies on the streets, this tree is already beginning to bloom.

When blossoming, very attractive earrings appear on alder, and they are both male and female. If during education they have a green color, then at the stage of ripening become brown-red.

Female earrings grows up to 1 cm long and are located on the branches of clusters up to 7-9 pieces. Male education grows up to 6-9 cm. Leafs on the plant appear only after its flowering.

Fruits of plants - greenish bumps. Throughout the winter period, they are closed, but with the arrival of spring are revealed, and seeds in the ground fall out of them. The cones ripen only in October - November. Sades note that the leaves of the alder are perfectly replaced by fertilizers, as they contain a large amount of nitrogen in themselves.

The average life expectancy of the plant is 100 years old. However, both long-lived trees are found, the age of which reaches 150-160 years. Most often, this plant is found in places with wet soil. It is for this reason that alder mainly grows around the reservoirs.

How the grenade grows and where the fruit is grown: description, varieties

If on the territory to determine the appropriate conditions for alder, then trees are formed - the trees are formed - Olds. In the regions of the North, this plant is found in the form of a coniferous tree. In the southern regions, it is not very common and occurs in mixed forests along with a beech and oak. The plant feels perfectly next to the ordinary aspen, lime, oak, fir and birch and some shrubs.

This tree can perform not only decorative functions, it is still a good honey. In the process of the development of Olha, leaflets and kidneys are formed, containing many resinous compounds in their composition, of which the propolis of the bee.

Black and gray grade

Black Olha received such a name for the colors of his bark. This plant was known in the times of ancient Greece. According to myths, it was often used on fire holidays as a symbol of the arrival of spring. This culture is light-friendly and is well refer to high humidity. But standing in the place where alder grows, can destroy the village. In this case, its root system can bend. Stagnation moisture can adversely affect how alder looks like.

Black variety has a rapid growth. The height of an adult sometimes reaches 22 m. Flowers on black varieties can be seen in early April.

This variety of plants need special care. It is noteworthy that the ebony is protected in such places:

  • some regions of Russia;
  • Kazakhstan;
  • Moldova.

The view in question is sometimes used to improve the squares, parks and private sites. It is best to plant such alder next to the reservoirs, where it will not only serve as an ornament, but also to strengthen the shore, as it is characterized by a very branched system of roots.

Gray grade alder grows up to 17 m. It is often used to strengthen ravines and coastal zones. It breeds in seed or stalling.

The trunk of gray wood has a characteristic grayish color. Sades note the high durability of this tree to frost. In addition, gray alder can fully develop even in depleted soils and on a wetland.

Application area

In addition to an attractive appearance, alder has and useful properties. It grows this tree fast enough, often creating wild thickets. At the stage of active development, plant wood has a uniform structure, therefore, it is easily processing. This allows you to apply it in the industrial sphere.

Alder - very popular materialwhich is used by artistic thread experts. It makes sculptures, decorative panels and kitchen utensils. A special value is the amid trunks decorated with influx.

Parts of this plant are actively used in alternative medicine. In the crust, sheets and bumps contain tann connections. Of them make tinctures and decoctions. Parts of this plant are distinguished by the following useful actions:

  • hemostatic;
  • antibacterial;
  • disinfectant;
  • anti-inflammatory;
  • binding.

So, you can put an a olch leaf on the bent wound, and it will soon be completely delayed. Alcohol tincture of alder earrings helps with constipation and hemorrhoids. To cope with eczema or diathesis, you can use brazers based on its flowers.


Alder Black (Alnus Glutinosa)

The plant reaches a height of 30 meters, the bark is dark brown, rough, covered with a network of small cracks.

Green Olha (Alnus Viridis)

This is a very common shrub (rarely small tree), with dense shoots. Reaches a height of up to 4 m. Creates numerous shoots bent in the form of braid. Annual olive-green or red-brown shoots slightly fightered, pubescent.

Photo of green alder
Earrings - Men's inflorescences. Leaves - egg-shaped or elliptical, up to 6 cm long, pointed, with double carved edges. The veins are clearly visible, in the amount of 5-10 pairs, in the corners slightly pubescent. Ripe fruit - bump. The fruit is a ball-like or egg-shaped, highly aided, reminds the view of tiny pine cones. Contain nuts. They remain on the plant for a long time.

The kidneys are convex, conical, covered with 4-6 purple-brown or greenish ciliary scales, sometimes slightly sticky. The plant is one-bed (on one plant there are separate male and female inflorescences). Before winter, men's and female inflorescences that bloom only in spring appear on the branches. They bloom at the same time with the development of foliage (April-May) and are wind-sour.

The plant grows especially richly along the streams. Prevents erosion and strengthens the slopes. His pollen sometimes causes allergies.

Origin: It is found in North America, Europe and Asia (including Siberia and Kamchatka).
