Derain white: description of varieties with photos, cultivation, reproduction and pruning


Garden plants

Derain white (lat.Cornus alba), or white svidina, or white svida, or telikrania white - a species of the genus Dogwood of the family Kizilovye, a close relative of svidina offspring, or silky. The natural range of the plant covers Mongolia, China, Korea, and also extends from the European part of Russia to the Far East and Japan. White turf grows in the undergrowth of swampy dark coniferous forests.
The generic name of the plant is translated as "horn". White turf shrub, as the most widespread species in culture, is widely used in urban landscaping.

Planting and caring for white grass

  • Bloom: abundant in the first half of summer, repeated in early autumn.
  • Landing: in the spring before the start of sap flow or during the period of leaf fall.
  • Watering: seedlings are watered 1-2 times a week, adult plants - 2-3 times a month in dry season, spending 1.5-2 buckets of water for each plant.
  • Top dressing: when grown in fertile soil, you can not feed it, and in the spring, under each bush, 100-150 g of complex mineral fertilizer is applied to the poor soil, and in the summer - 5-7 kg of humus.
  • Cropping: from the age of three, twice a year: in July and in August. Species with brightly colored bark are sheared in early spring once every few years.
  • Reproduction: seeds, layering and cuttings.
  • Pests: scale insects comma-shaped and aphids.
  • Diseases: powdery mildew.

Botanical description

White Derain is a branched shrub with straight, bare and flexible branches of coral-red, black-red or red-brown color, arcuate bending with age. The height of the white turf can reach 3 m. The leaves of the plant are 2 to 10 cm long and 1 to 7 cm wide, opposite, entire, elliptical, petiolate, pubescent, with three to five distinct arcuate veins. The upper side of the leaves is dark green, the lower one is bluish. Small white flowers with four petals are collected in dense terminal shields with a diameter of 3 to 5 cm. Abundant flowering takes place in the first half of summer, and in early autumn, the white turf blooms again. The fruits of the white turf are berry-shaped drupes, bluish when unripe and bluish-white, flattened after ripening. And blooms, and bears fruit white tree from two to three years of age.

Derain white is characterized by winter hardiness, heat resistance, shade tolerance, grows well on any soil and in urban conditions. He is as beautiful as unpretentious.

Planting white deren in the open field

When to plant

Planting and caring for a white turf does not require any special skills. You can plant white turf in early spring, before the start of sap flow, or during leaf fall. For most gardeners, an autumn planting of a plant is preferable, since with the onset of spring, overwintered seedlings immediately start growing. If you decide to plant a white turf in the spring, try to keep as much soil as possible on its roots, in which the seedling grew, to protect the root system from transplant stress.

White derain grows normally in partial shade and even in the shade, so it is often planted under trees or along blank walls and fences. However, variegated forms require bright lighting, otherwise their foliage will lose its original color.

How to plant

The composition of the soil is not of great importance for the plant: white turf can grow on light sandstones, and on stony areas, and in heavy loams. The only requirement is a neutral soil acidity level.

The best planting material is seedlings not older than 4 years: they quickly take root and give many young shoots after pruning. Before planting, place the root system of the seedlings in water for several hours so that the roots are saturated with moisture and adapt more easily. Seedlings with a closed root system do not need such a procedure.

The size of the planting pit for the white turf should be a quarter larger than the volume of the root system of a plant with an earthen ball. In order for white turf to grow and develop normally in marshy soil, it needs to provide good drainage: a layer of broken brick or rubble mixed with sand, about 15 cm thick, is laid on the bottom of the pit. great depth, drainage into the planting hole can be omitted at all, or only a layer of sand can be dispensed with.

Fill the space around the roots with a mixture of soil from the upper fertile layer with compost and humus. After planting, the surface is tamped, watered abundantly, and when the water is absorbed, the near-stem circle of the seedling is mulched with organic material. The root collar should be level with the surface.

White derain care

Although the white turf bush is unpretentious, it still requires attention to itself. Sod care consists in watering, loosening the soil and removing weeds in the near-stem circle, top dressing, pruning and protection from diseases and pests.

Most of all, young and newly planted plants need watering, which need to be watered 1-2 times a week. An adult turf is watered only in severe drought. In the hot season, 2-3 waterings per month are quite enough at a consumption of 1.5-2 buckets of water for each plant. After moistening, loosen the soil in the trunk circle and remove the weeds.

It is desirable to feed white turf, but not necessary, especially if it grows in fertile soil. In order for the plant to have a healthy and blooming look, you can apply 100-150 g of complex mineral fertilizer under each bush in the spring, and 5-7 kg of compost or humus in the summer.

Regular formative pruning of white turf is carried out from the age of three, otherwise the lower part of the bush will soon begin to bare. To keep the bush compact, you need to remove every third or fourth shoot on it, leaving only strong and developed branches on the plant. The hedge bushes are cut for the first time in July, and the second time in August, after the shoots have grown. Deren varieties with brightly colored bark are sheared once every few years in early spring, before budding begins: the bushes are cut completely at a height of 20 cm from the ground. This pruning stimulates many young shoots to regrow.

As for the formation of a bush, the popular forms in landscape design are a column, an arc, a hemisphere, a cube, a ball and other shapes. You can form a plant in the form of a standard tree, in one trunk. And you can maintain the natural shape of the crown, especially since some varieties of white turf look great without formative pruning. Such plants only need annual sanitary cleaning.

Adult white turf bushes are rarely affected by infections and pests, but young shrubs are vulnerable to powdery mildew, comma-like scale insects and aphids. As soon as a sloppy whitish bloom appears on the leaves of the plant in spring, immediately remove the affected branches and treat the bush with one percent Bordeaux liquid or Fundazole solution. And against aphids and scale insects, a solution of any acaricidal drug should be used, for example, Aktara, Aktellik, Akarin, Bankol or Biotlin.

Reproduction

White dogwood propagates by seed method, layering and cuttings. Seed germination of the plant is close to 100%. Derain is sown in the fall, immediately after harvesting the seeds. White turf can also be sown in spring, as its seeds remain viable for up to five years, but during the winter they need to be stratified by keeping them in a refrigerator at 5 ºC for at least two months. Sowing grass is sown with a density of 5 to 15 seeds per square meter, sowing depth - 4-5 cm. Seedlings germinate for a very long time, sometimes in the second or third year. And keep in mind that you will receive a standard-sized white turf bush with seed propagation only after 5-8 years.

Varietal plants are best propagated by faster and more productive vegetative methods. How to propagate white dogwood by cuttings? Cut slightly woody cuttings with 7-9 buds from a strong, healthy bush in early June and plant them in a container with suitable soil. Rooting is best done in a greenhouse. Caring for cuttings consists in moistening the soil and feeding with organic and mineral fertilizers. By the beginning of autumn, you will receive independent seedlings with a well-developed root system.

The easiest way to propagate white turf is by rooting layers. In spring, tilt the low-growing, flexible shoot of the plant towards the ground and completely submerge it in the pre-dug groove, leaving only the top above the surface. Secure the branch in this position and fill the groove with nutrient soil. Remember to water and fertilize the cuttings during the summer. For the winter, it is better to cover the layers with foliage or spruce branches. The seedling can be transplanted to a permanent place next spring or autumn.

Varieties

There are several decorative garden forms and many varieties of white deren. Garden forms include:

  • derain white argenteo-marginata Is a plant with red bark and green leaves bordered by a creamy white rim. In the fall, the foliage becomes carmine red. The most popular variety of this form is the white grass Elegantissima - a shrub up to 3 m high with spectacular red shoots and wide, uneven creamy-white edging of leaves, which, in addition to the border, have spots and stripes of cream color;
  • garden form Sibirica - undersized plants with bright red shoots and light green leaves, which turn reddish-brown in autumn. Popular is the white turf of Siberica Variegata - a shrub up to 2 m high with a wide creamy edging of leaves, as well as spots and strokes of cream color. In autumn, the green part of the leaves turns purple. This variety is similar to Elegantissima, but grows more slowly, therefore it is suitable for small gardens. White Aurea is also in demand among gardeners - a shrub up to 2 m high with pale yellow leaves, reddish shoots, creamy white flowers and bluish-white fruits;
  • garden form Kern - plants with green leaves in yellow spots;
  • Derain white Shpeta - a garden form, bred about a century ago and representing plants up to 2 m high with brown-red shoots and a wide, uneven golden-yellow border along the edge of green leaves. In autumn, the leaves turn purple;
  • Derain white Kesselringi - Plants with black-red or purple-black shoots.

Such varieties of white deren are also in demand in culture:

  • Astrosanguinea - a plant with green leaves and crimson shoots, reaching a height of one and a half meters;
  • Allemans Compact - a bush with bright green foliage and red shoots at a young age;
  • Aurea Elegantissima - bush up to 2 m high with yellow-pinnate leaves;
  • Blood Good - shrub 2-3 m high with red coral shoots and leaves;
  • deren white Gochaulti (Guhalti, Gusholti) - a plant with blood-red shoots and slightly drooping green leaves in white, pink and red spots;
  • Ivory Hallow - variety with a spherical crown, red shoots and green leaves with a wide white-cream border;
  • Siberica Ruby - shrub up to 1.5 m high with coral-red shoots, rounded dark green leaves, which turn red-purple in autumn.

Derain white in landscape design

Most often, white lawn, plastic and easily tolerant of pruning, is used to create a hedge. Variegated and beautifully flowering forms of white turf are effective both as salt plants and in group compositions. Due to the fact that white dogwood feels great in waterlogged soil, it is often used to decorate and strengthen the banks of artificial reservoirs, where it gets along well with hosts and other coastal perennials. White turf is also planted in areas with complex multi-level relief.

Since white turf grows equally well both in sunny areas and in the shade, it is often planted under large trees. The bright shoots and leaves of the deer are perfectly combined with evergreens. The indisputable advantage of white turf is that it remains attractive throughout the growing season.

Derain White Aurea: description, planting and care, photo

White Derain is a deciduous shrub native to the Far East, where it grows in river floodplains, in wetlands. Gardeners liked the decorative qualities of the plant, so they use it to create hedges and single plantings. The Aurea variety was bred by breeders specifically for growing in gardens and parks.

General information and description

The height of the Aurea variety is 2 meters, the diameter of the bush is 2-2.5 meters. The leaves are large, wide, when they appear, at the beginning of summer they are burgundy-brown, gradually turn green, then lemon-yellow, and by autumn they turn red again. Such inconsistency of colors attracts gardeners.

In general, the bush turns out to be lush, with a large number of branches, from which it is easy to form a hedge, decorative figures, or fencing alleys and paths in the park.

The flowers of the deren are not large, creamy white, grow in inflorescences, exuding the aroma of nectar that attracts bees. It begins to bloom in June, in warm and humid summers it can bloom in September. In place of the flowers, blue-white fruits appear over time. When re-flowering in autumn, on the bushes, you can simultaneously see both bead fruits and flowers. The red and dense shoots of Aurea look great in winter, against the backdrop of clear, white snow.

Care and cultivation

During the growing season, the Aurea grass grows 20 cm, with good care it can grow a little more. It is better to plant it in sunny, bright places, in extreme cases - in partial shade.

In natural nature, grass grows in wetlands, which means that it can also be planted in the garden on the ground with high groundwater. In a normal area, it is necessary to provide the shrub with constant and abundant watering.

Derain Aurea is characterized by high winter hardiness; there is no need to cover it for the winter. For the winter, only young shrubs, the first year of planting, are insulated.

Pruning is carried out in the spring, removing damaged shoots, and giving the bushes the desired shape. Old bushes are cut low - 30-40 cm from the ground, this procedure avoids exposing the branches from the foliage from below, and as a result, a lush, branched bush.

The dogwood is propagated by root shoots, layering and cuttings. Cutting begins in June-July, cutting off two-year lignified shoots. They root well in containers with soil, and spend the winter in a basement or greenhouse. It can be planted in open ground with the arrival of real heat the next year.

Root shoots are separated from the bush in the same way - in the spring, before the leaves open. Layers are made in early spring or summer. After final rooting, they are separated and transferred to a permanent place.


Shrub features

Derain is a shrub from the dogwood family. It grows in forests at the edges, and near rivers and lakes. It can grow up to four meters in its natural habitat. Shoots of a young shrub are flexible. They are green at first. But the closer the autumn, the redder their color.When all the shrubs shed their foliage and look less attractive, the turf remains bright. Its red stems stand out against the general background and continue to decorate the garden even in winter.

But his description is not limited to this. The leaves of the plant are oval, covered with hairs. In spring and summer, they have a dark green color, but by autumn they gradually turn red and towards winter they acquire a burgundy hue.

The leaves of the deren are quite large and can reach more than five centimeters in diameter. At the very end of spring, flowers of a cream or white shade appear on it, which delight with their beauty for almost a month.

But to wait for flowering, you need to be patient. The first flowers appear on the shrub at the age of seven. With good care and a favorable climate, flowers reappear closer to autumn. In autumn, the shrub is covered with small black berries that should not be eaten. The hairs on the leaves turn red. That is why the shrub got its name - blood-red turf. A tree can grow and feel good in one place for 25 years.

Due to its decorative qualities, it is ideal for decorating hedges, various compositions, alpine slides. The shrub is very convenient in that it easily tolerates both drought and frosts of the middle zone. That is, it can be grown in many regions. It is unpretentious to the soil, the structure of the roots is such that there are many lateral branches. Many people use this quality of plants in order to strengthen the slopes.


Features of the white deren

Derain white is a highly branching shrub. Its bare and straight branches are quite flexible, and over the years they begin to bend arcuate. Branches can be colored red-black, red-coral or brown-red. The height of the bush can reach up to 300 cm. The entire opposite leaf plates have an elliptical shape, petioles and pubescence on the surface. Their width can vary from 10 to 70 mm, and their length - from 20 to 100 mm. On the surface of the plate, three to five arc-shaped veins are clearly distinguishable. The front surface of the foliage is of a dark green hue, and the seamy side is pale gray. Lush apical corymbose inflorescences reach 30-50 mm in diameter, they include small white flowers with only 4 petals. Lush flowering of the shrub occurs at the beginning and middle of the summer period. And in the first weeks of autumn, repeated flowering is observed. The fruit is a berry-shaped drupe. Unripe fruits are painted in a pale blue color, which changes to white-blue as it ripens. Ripe drupes become flattened. Fruiting and flowering in white turf is possible only after it turns 2 or 3 years old.

This plant is resistant to heat, cold, tolerates winter well, can grow in the shade, any soil suits it, and it also feels great in urban conditions. It is thanks to its unpretentiousness and spectacular appearance that such a shrub has gained great popularity among gardeners.


Derain red, or svidina blood red

Another species is red dogwood (Cornus sanguinea). Slightly less common in gardens than white turf. Flexible green shoots acquire a red tint over time. Pointed ovoid leaves are covered with villi. Dark green in summer, in autumn they glow with all shades of red. Thanks to the autumn color of the leaves, the species got its name. Blooms in the seventh year in late spring. Small white flowers are collected in scute inflorescences. Re-flowering sometimes occurs. In August, black, round, inedible fruits ripen.

Derain red is also an unpretentious look, quite frost-resistant, but in severe winters it can freeze a little.

Has decorative forms and varieties:

  • Compress (Cornus sanguinea Compressa) - a very interesting shrub with crushed, rounded leaves. The foliage is dark green in summer, turning red in autumn. The crown is dense, vertical, about 1 m high. The bark on the branches is reddish-brown. Does not bloom.

  • Winter Beauty (Cornus sanguinea Winter Beauty) - the owner of a round, spreading bush (about 2 m). Shoots are orange-yellow. Leaves are oval, pointed upwards. Dark green in summer and red in autumn.

  • Midwinter Fire (Cornus sanguinea Midwinter Fire) - a spreading shrub up to one and a half meters, shoots are bright red-orange. The leaves are rich green in summer, by autumn they change color from yellow-orange to dark red.
  • Varigeata (Cornus sanguinea Variegata) - a variety with variegated leaves, they have yellow-white spots and a border on a green background, then the leaves turn red. Young shoots are green, but gradually acquire a burgundy hue.

We also note some more of the decorative forms:

  • Atro-sanguinea - with deep purple branches.
  • Viridissima - differs in bright green fruits and shoots.
  • Mietschii - young twigs and leaves of an unusual light yellow color.

The varieties of blood-red svidina considered by us, like white turf, are frost-resistant.


Diseases and pests

An adult plant is immune to most diseases, but young shoots are susceptible to powdery mildew attacks. The leaf plates are covered with a white bloom, spreading from the roots to the tops. Favorable conditions for its manifestation are temperature drops and waterlogging of the soil. For the prevention of powdery mildew, it is recommended to plant Derain White Aurea at short intervals and water at the root.

When infected with powdery mildew, the shoots are cut out, the bush is treated with disinfecting drugs.

The main pest is the scale insect. She destroys the leaf plates, which can lead to the death of Derain the White. For its destruction, treatment is carried out with the means of Decis, Karbofos.

It is possible to find on the plant and aphids: it prefers to be located on flower buds, less often on stems. As a treatment, the bush is treated with a solution of garlic or celandine.


The use of a plant in landscape design

The culture is planted alone and in a group with other plants. Used for mixborders from coniferous and deciduous shrubs. A hedge made of white turf looks great, and it also adorns the winter garden. Also, the plant is used for landscaping city streets. He can often be seen near schools, medical facilities, in squares and alleys. All this is possible because the plant is resistant to dust and city exhaust fumes and is compatible with many plants. Derain white grows in the company:

  • Coniferous shrubs
  • Spireas
  • Barberry
  • Fern
  • Ivy
  • Alyssuma

So, white turf is great both for decorating a suburban area and for landscaping a city. Its unpretentiousness allows it to be grown in the harsh climatic conditions of our country.
