We continue to talk about Astrakh, but now about perennial.
Luxurious bushes with pink, purple and violet, carmine-red, lilac and white flowers perennial asters - the last generous gift of autumn.
Precisely in the fall comes the finest hour perennial asterswhich, transforming our autumn gardens with their dazzling beauty, make them truly beautiful on the eve of winter.
In our country, they are often called Oktyabrins, Septibrins, freezers.
Perennial Asters Blooming in the Autumn
The most famous perennial asters blooming in the fall are new belgian (virgin) and new english (american)
This large family of autumn asters includes delightful beauty species that bloom to the very cold and with flowers often go under the snow.
Astra New England can grow to a height of about 2 m. Flowers with a diameter of 3-4 cm, collected in 20-35 pieces in a thick brush. This aster blooms in September - October.
Astra is a new Belgian in height of 50-160 cm, the stems are woody, flowers are terry with a diameter of about 5 cm and mostly lilac, pink colors. Blooms aster Novobelgi also in September.
On each of its shoots up to 150 flower baskets are dissolved, and they are very densely arranged, therefore there is not even visible leaves between them.
Astra Bush only 50 cm high. The entire surface of a dense bush is covered with white or light purple flowers.
This aster blooms from mid-September to frost. Low (30-35 cm), spherical-shaped bushes, with delicate lilac flowers, look especially great.
Blooming in summer
Talking about the perennial aster, it is impossible not to name the plants that bloom in summer.
Alpine aster - A low (30 cm) plant, which is most often found in our gardens, blooms in May. Her flowers look like simple daisies.
In July blooms Astra Chamomile lilac reed single row long flowers. Their baskets are 4-5 cm in diameter, in the middle there is a small disk with a diameter of 1-1.5 cm.
Sometimes it is used as a groundcover, because the stems 50-70 cm long are unstable and often lie on the ground, rising at the ends.
In our gardens, it is still rare. Blossoms very plentifully up to the snow.
In early August, blooms Astra flax-shaped. It is found in the gardens of the middle lane, though not so often. For good growth, it needs a lot of sun.
Feels good on poor soils and withstands drought. Her inflorescence is very different from all perennial asters.
It has no reed flowers. Baskets with a diameter of 1.5 cm, consisting of mid-yellow flowers, are collected in corymbose inflorescence.
Already in the gardens Astra shaggy. It also blooms in early August and is very good in a curb. Its height is only 25-30 cm, oval leaves, densely covered with white fibers, seem silvery.
In the second half of August, blooms Astra is cleanforming a lilac cloud with its daisy flowers. Strong, straight stalks densely covered with small narrow leaves grow to a meter, acquiring a spherical shape due to branching.
Cultivation and care
Perennial asters are extremely frost resistant, and when autumn frosts damage other flower crops, asters are still fresh and continue to delight us with their flowers.
They are light-requiring, they should be grown in open, sunlit areas.
It is also possible to grow in the penumbra, but not desirable, since the likelihood that asters can be affected by powdery mildew, in such conditions increases (especially in rainy summer).
Therefore, in order to avoid this disease, all perennial asters, no matter where they grow, I advise you to sprinkle it with Topaz before flowering.
And in the fall, after flowering, it is good to treat with copper sulfate (10 g per 10 l of water).
Perennial asters to the soil are not demanding, but prefer quite fertile. Without a transplant, asters can grow in one place for 5-6 years.
Plants respond well to the introduction of phosphate fertilizers and lime. Top dressing is best done dry, followed by watering of the bushes.
But if summer is hot and dry, then it is better to give top dressing only in liquid form.
Plant care throughout the summer-autumn period consists in loosening the soil, removing weeds and watering as needed.
Perennial asters can be propagated both by seed and by dividing the bushes. Shrubs are divided in early spring when asters start to grow.
Each delenka should have one kidney and several roots. Landing scheme - 20x30 cm (undersized species) or 50x80 cm (high types).
Asters grow rapidly, forming powerful bushes. In the spring, I advise you to pinch the young shoots of tall varieties, so that they bush more, not too stretched to a height, because during flowering heavy bushes can lie down from the wind and rain.
Now it seems that everything I wanted to tell about asters.
Appearance and variety of asters
Astra perennial differs from oak trees (chrysanthemums) in the absence of a characteristic odor and small, simple leaves. The shrub consists of heavily branched, strong, woody stems. A small flower is in fact an inflorescence of small yellow flowers without petals bearing reproductive organs, and surrounding one petal different, depending on the type, color. The latter are needed to attract fall asleep insects. In terry inflorescences of false-lingual flowers more.
In turn, the inflorescences (up to 8 cm in diameter) are gathered in panicles or umbrellas, arranged in groups on each shoot. The height of the shoots can be from 10 cm to 2 m.
The underground part is represented by a long horizontal rhizome, where buds of future sprouts and suction roots are laid. Rhizome branches, taking up space new plants. Bush curb (undersized) asters with sufficient illumination takes the form of a hemisphere, abundantly blooming by autumn. Tall flowers will have to tie up.
When blooming, aster scatters elongated dry fruit with flying fibers in the wind. Individual buds can unfold even after frost.
Up to 200 species of perennial aster are known, 80 of them are grown in gardens, decorate flowerbeds and balconies. By flowering time, they are divided into three groups:
- spring (May - early June),
- summer (June, July, August),
- autumn (from the beginning of September to frost).
The most popular of the early asters is the Alpine. Bushes up to 30 cm high are used for borders, alpine slides. Flowers have different colors from white to lilac. For spring-summer flowering the following varieties are suitable:
- Wargrave pink is a bright Englishwoman in a corolla of rich pink color with a yellow center, the width of a low spherical bush reaches 50 cm. The main flowering occurs in June.
- Happy End - pink flowers, differs from the previous variety in shorter petals and a wide yellow center. Flowering begins in May.
- Albus - white flowers that look like daisies. It blooms in June, prefers a warm climate.
Alpine asters have summer varieties:
- Dunkle Schone - light purple flowers with wide yellow centers, inflorescence diameter - 4 cm, bush height 20-30 cm, few leaves, they are completely hidden flowering crown.
- Helen Beauty - pink flowers on dwarf shoots up to 15 cm.
- Dark Beauty - dwarf variety, dark purple semi-double flowers.
- Alpine pink - up to 30 cm tall.
- Goliath - height 25 cm, blue petals.
Summer varieties of Italian asters have a height of 50–60 cm, large lilac and purple flowers that do not wither for more than two months. Top grades for warm climate:
Summer varieties include the high Bessarabian aster with purple chamomile flowers with a dark yellow middle.
This is the largest group of varieties and varieties that begin flowering in August. These include:
Shrub (bush aster) - very dense crown, amenable to formation. Numerous inflorescences that hide foliage. Plant height - from 30 cm to 1 m. The most impressive varieties are Alice Haslam (semi-double bright pink flowers), Jenny (a low dense bush with crimson flowers), Lady in Blue (height 40 cm, blue needle-shaped petals, yellow center), Christina (white) and others.
New Belgian and New England perennial asters are bushes with a height of more than 1 m, widening upwards, flowers are terry from 4 to 6 cm in diameter. Bright, saturated colors.
Popular varieties of New England asters - Barrs Pink (bushes up to one and a half meters, topped with pinklilac inflorescences with dark yellow center), Barrs Blue (bluish-lilac), Braumen (lilac, bush up to 1 m tall), Constance (lilac, large flowers, height up to 2 m), Roter Stern (pink), Dr. Ekener (lilac) .
Novobelgiyskie are distinguished by high growth and an abundance of small flowers, mostly purple Popular varieties: Herbst Wunder (white), Royal Blue, Rut Ballard, Saturn, etc.
The disadvantage of tall asters is fading lower leaves, exposing the lower part of the shoots, because of what the bush looks sloppy. The rest - only benefits: the plants are resistant to disease, frost, stand perfectly in bouquets.
Fans of unusual colors can try to breed yellow Matsumoto shrub asters (up to 65 cm tall, yellow inflorescences), red (real red), two-tone (white-lilac), Red Brocade, New Sam Sam Betham (white chamomile) and Crimson Brocade (dark red with a yellow center).
Spray asters for the border is better to multiply by dividing the bush. In the autumn, a carefully dug root is shaken off the ground, lateral shoots and buds are determined. You can divide into small parts, it is important that on a piece of rhizome was not less than one escape Such delenki acquire decorative effect only in the second year of life. A shallow (15–20 cm) trench is dug along the path and the planting material is laid out at a distance of 30–50 cm, placing the rhizome horizontally. To neutralize the acidity of the soil, you can add ash, dolomite flour or fluff.
After sufficient growth of bushes, they can be trimmed, separating the side shoots with roots. The processes are continued curb. In the spring begin feeding with compost or mineral fertilizers. Further care is to timely watering and loosening, avoiding overwetting.
When signs of disease appear and for prophylaxis, they spray the plants with Bordeaux mixture (after rains), fight against cicadas and aphids. If the disease overcomes - you need to take care of the disinfection of the soil. For this, the landing site is either sprinkled with boiling water or a campfire to destroy the fungus spores.
If the year was unsuccessful for asters, the plant may not bloom or give only a few small inflorescences. In order not to lose the autumn beauty of the garden, it is recommended to combine the bush asters in the borders with the spray chrysanthemums, the stonecrop, and the cravat.
Care for tall asters
Planting high varieties of asters produced at a distance of not less than 40 cm from each other. These plants dry the soil so it must be ensured necessary care. Nearby you can plant decorative cereals, delphinium, conifers will be a good background. Ugly lower parts of the bushes masked stunted asters. In this case, you need to timely dig up the lateral growth, otherwise the tall “masters” will quickly force out all the neighbors from the flower bed.
Especially sprawling bushes are tied with wire or bundle of inconspicuous coloring. Vertical support is usually not required. Watering and feeding - as stated above.
Astra: plant description
This is a perennial shrub from the Asteraceae family. Do not confuse it with annual asters, which are often called callistephus. Under natural conditions, the perennial autumn aster is found throughout the world: it grows in Asia and Europe, America and North Africa. Cultivate this plant began at the end of the XVI century. The name of the flower is translated from Greek as "star". As the legend goes, aster appeared on Earth from fallen star dust. The Greeks were convinced that this flower brings good luck, it was their amulet.
Autumn Astra belongs to perennial and annual plants. In the world there are, according to various sources, from 200 to 500 of its varieties. Their overwhelming number grows on the territory of North and Central America.
The plant has simple leaves and inflorescences-baskets, collected in shields or panicles. Depending on the variety, they differ:
Most often, the autumn aster has needle flowers. Annual varieties are grown in central Russia and northern regions. In the south, perennials prefer. All species are characterized by long and beautiful flowering, excellent resistance to adverse climatic conditions. These are light-loving and drought-resistant plants.
Among the late-flowering autumn asters are several popular varieties - the new Belgian, New England, and shrub. New Belarusian asters grow to a meter and a half. Bushes have many branches, densely covered with leaves. At the same time there are stems with virtually no deciduous mass. In the color range of this group is dominated by lilac-lilac shades, sometimes there are pink and red. A very impressive bouquet of asters of this species.
This variety blooms for almost a month with semi-double dark purple flowers. Up to six flowers with reed petals are formed on one stem.
Another amazing sort of asters. A bunch of them looks amazing. In addition, this variety is often used for planting in flower arrangements. Bushes bloom very lushly, and therefore often used for a single planting. Flowers are small, bright pink.
Bushes grow to a meter and a half. Lush blue inflorescences with a diameter of four centimeters delight the eyes for almost a month.
Perennial bush aster
The plant is a compact, but dense flowering bushes. They do not grow to a height of more than fifty centimeters. This variety blooms in early September and pleases with beauty before the onset of the first frost. Flowers have a white or light purple color.
Another short-growing bush autumn aster, which can even be called dwarf, since the plant height does not exceed 25 cm. The variety is ideal for creating a composition of low-growing plants as the main element or as a border. Color can be sky blue or in mauve tones.
Also applies to dwarf varieties, a height of about twenty centimeters. It is used as a suspension option for framing flower beds. Blooms one of the last, later other varieties. Purple-pink flowers delight for a month starting in September.
New England asters are distinguished by several main characteristics:
- thick shoots
- powerful bushes with straight and tall stems.
Bush up to a meter in bloom in September. Beautiful lush inflorescences are collected in a brush purple-lilac color. Flowers are equally good in bouquets and flowerbeds. It is often used as a hedge.
Tall autumn flowers. Asters of this variety grow to one and a half meters. This magnificent plant blooms with red-purple flowers with a diameter of 4 cm during the month.
An amazing variety of autumn perennial asters with rather large flowers of carmine shade. The height of the bush reaches one and a half meters.
Preparing asters for landing: the choice of location
We briefly described the popular varieties of autumn asters, now it's time to get acquainted with the conditions of planting. To obtain a beautiful flowering plant, it is necessary to choose the right place for planting and prepare the necessary soil.
You can grow autumn perennial asters anywhere, but if you want to get lush bushes and achieve active flowering, you need to choose the most suitable place on the site. Astra feels great in open, well-lit areas. Sunlight contributes to the development and growth of the entire bush, and not just the foliage and stems.
We must not forget that in most cases, the choice of site for planting depends on the type and type of aster. If you decide to plant several varieties, select them in height. Thus, when the earlier varieties fade, they will not close later ones. For framing tracks are suitable for stunted or dwarf, and tall look good along the fence.
When to plant asters?
Planting, reproduction and transplantation of perennial asters is done in spring and autumn. Planting material is desirable to purchase in specialized stores or in nurseries. Plants can be planted with seeds, seedlings or cuttings and dividing the bush, if you already have at least one plant in the area.
Planting asters by seeds
This method of growing asters is only suitable for the alpine variety, in the case of the rest it is ineffective. This is due to weak seedlings that take root poorly. The seeds of perennial aster are sown in the fall, immediately after they are harvested. But Alpine Astra is more suitable for planting spring, when the soil warms up well. With the onset of stable heat, the first shoots appear, and in the fall young plants are transplanted to a permanent place.
Когда всходят первые ростки, растению требуется обильный полив, рыхление и подкормка. На одном месте многолетняя астра должна расти не более пяти лет, после этого ее пересаживают.
Это самый популярный и распространенный способ посадки, а также размножения астр. Подготовку к нему начинают весной, когда молодые побеги только появляются. Срежьте верхушки побегов длиной около пятнадцати сантиметров таким образом, чтобы нижний срез был наклонным. Lower leaves are removed completely, leaving only two or three upper.
Before planting, the cuttings should be held in a growth stimulator, in accordance with the instructions. Then plant them in the soil (tilted!) In a special cover with a film. To do this, partial shade. Rooting usually occurs within a month. The ideal soil mixture in this case is peat, sand and turf ground. Experienced growers recommend processing substrate with potassium permanganate. In this position, the cuttings are left until next spring for rooting, and then transplanted to a permanent place.
This method is suitable when you need to transplant an adult bush to a new place. As we said, this must be done in five years. When to plant asters in this case? This can be done both in spring and autumn. Early varieties are more suitable autumn, and late - spring.
When dividing a bush, it is necessary to dig up and remove the whole earth from its roots. Only after this, the sharp and disinfected shears separate parts with young shoots and roots.
Peculiarities of care
Despite the fact that autumn aster is considered an unpretentious plant, certain rules for its care still need to be followed. Only in this case you will achieve a long and active flowering.
It is carried out constantly, and in dry time the volume of water must be significantly increased. This is especially important when growing green mass.
Mulching and loosening
We have already said that asters need light and breathable soil. That is why it is necessary for the plant to loosen and remove weeds during the season. This process can be minimized using mulch. For this suitable peat, sawdust or bark. This will help retain moisture in the soil, prevent it from drying out and, very importantly, slow down the growth of weeds.
This is an obligatory procedure, because asters like nutrient rich soils enriched with organic and mineral fertilizers. During the growing season it is important to feed the plant with humus and phosphate fertilizers. This will support the bushes, fill them with power before flowering.
Trimming and Garter
Depending on the variety and the type of autumn asters, they also need additional care. Shrubs and undersized compact varieties need pruning to form a beautiful crown. If the flowers are planted along the paths, then using pruning will be able to create the perfect hedge.
Tall bushes will need support because they can grow up to two meters in height. As a rule, long strong pegs are used, or the plant is planted along the fence.
Astra New Belgian (virgin)
Astra New Belgian (Aster novi-belgii) - the largest group of perennial asters with more than 1000 species. This is not a species as such, but a group of hybrids exhibiting a great variety in height (from 30 to 90 cm) and the shape of the bush, as well as the color and size of the flower. The size of the plant depends on the type of soil on which it is grown. Asters growing in areas with rich loams will be higher than those planted in well-drained sandy soil.
Astra New Belgian
Given the huge variety of sizes and colors, you can choose a plant for every corner of the garden. But their most important advantage is the flowering time. The main season is September and October, some species bloom at the very end of October and continue to bloom in November.
Features of growing
New Belgian asters grow well in full sun, soils prefer from slightly acidic to alkaline. It is necessary to ensure that the earth was always moderately wet. Particularly close attention in this regard require large overgrown bushes.
As a rule, propagated by dividing the bush, although seed reproduction and green cutting is possible. When planting, you need to be well aware of the size of adult bushes and not crowd them, but on the contrary, to achieve free blowing with the wind of each plant. To maintain a high decorative rate, it is necessary to divide every 3-4 years. In some cases, for this, it is not even necessary to dig out the whole bush. Instead, one or two parts are cut off from the mother plant with a sharp shovel and carefully removed. The remaining hole filled with fertile soil and watered.
Novobelgiyskie asters often suffer from fungal diseases, especially susceptible to powdery mildew (in connection with this, breeders are now working on breeding resistant varieties). For preventive purposes, it is advisable to plant the plants freely, without thickening, far from the oaks, on the leaves of which a large number of various fungi parasitize. In rainy years, it is necessary to periodically spray asters with copper-containing solutions or fungicides (for example, Fitosporin, Topaz).
Here are some popular hybrids that have proven themselves from the best side.
- 'Marie Ballard' - plant height 90-100 cm, blooms in August and October with numerous lilac-blue flowers. Winter hardiness is high. Prefers friable rich soils, grown in the sun and in partial shade.

Astra New England (American)
Asters of New England (Aster novae-angliae) Currently, about 50 varieties are bred. The species was introduced to Europe in 1710, but did not arouse such stormy interest as the new Belgian asters.
Astra New England and Butterfly Admiral
The homeland of these asters is Quebec, South Carolina, Kansas. They are ideal for informal landscape type gardens. In combination with cereal and other autumn-flowering perennials (especially with rudbeckia), these asters make wonderful compositions. It is also important that they are distinguished by good frost resistance and grow up to the taiga zone.
Astra is shrub
Astra is shrub (Aster dumosus) - frost-resistant form with upright pubescent stems up to 50 cm tall. Homeland - North America. There is some confusion in the classification and the fact that the catalogs is called dumosus-hybrids - is the result of the crossing of shrub asters and Novobelgiyskoy. As a result, we received a large variety of flower colorings at the same plant height. In nurseries, these asters can be called and new Belarusian, and shrubby, and dwarf new Belgian asters (Dwarf Novi-Belgii Asters).
Astra bokotsvetnaya (Aster lateriflorus) - A wonderful autumn aster blooming in September. It grows up to 120 cm. The flowers are very impressive: at the ends of strongly leafy shoots - in the form of a bunch of grapes. The color of the petals is white or pale purple, the middle at the beginning of flowering is yellow, and later - purple.
- 'Prince' - one of the most famous cultivars. It grows up to 120 cm, blooms in September with pastel-purple flowers.

It will adequately cope with the role of a tapeworm, but it will not get lost in a group planting, it will be in place in mixborders.
Astra heather (Aster ericoides) in culture since 1732, her homeland - the southern regions of North America. It grows into a branchy bush with a height from 80 to 105 cm. It blooms from September to October, forming numerous small inflorescences with a diameter of 1 cm. The plant is light-loving, frost-resistant. Plant should be on fertile soils, not thickening. Looks great in group plantings with solidago, liatris, stonecrop.
Astra heather 'Schneetanne'
There are still such types of perennial asters of the autumn time of flowering, as the aster spread out (Aster divaricatus), cardiovascular (Aster cordifolius), Tatar (Aster tataricus), but they are found in nurseries much less often.
Given the variety of varieties and hybrids, as well as winter hardiness, unpretentiousness and ease of cultivation, perennial asters can take a decent position in our gardens. Do you already have such asters in your garden?
Low-growing varieties of perennial asters are an excellent plant for rockeries and borders, they will look good on the lawn. Tall asters can be placed in the center of flower beds and even create a flowering fence from them. Do not really forget that these plants are not very attractive lower part of the stem, so they are better covered with lower perennials, such as, for example, Korean chrysanthemum, autumn gelenium or host. Very good asters and for cutting. In water, flowers can stand up to two weeks.
Types of asters
The flower can be found in many gardens, it is deservedly popular with gardeners. This amazing plant has been cultivated already 500 years ago. Astra can have a different stem height, able to tolerate the first frost.
There are more than 500 types of these delicate flowers, but only a small amount is used in landscape design. Depending on the variety, the plant makes us happy in summer and autumn. By flowering time, these types are distinguished:
- early plant, blooming from May to the end of June,
- summer varieties that delight us with their beauty from July to August,
- autumn flowers adorning the flower beds in the autumn months.
Multi-colored stars will be a great decoration for the front garden of a country house. They will delight the hosts and guests with their magnificence even on rainy autumn days.
Early aster perennial alpine
The stunted plant is the most common species. It looks great along the tracks, used for disembarking at the edges of the flower bed. Single inflorescences come in different colors.
Varieties that are popular with gardeners: white “Albus”, pinkish shades “Rosea”, light blue “Gloria”. Astra "Happy End" is ideal for mixed compositions.
Amazing Italian flower is a perennial. These flowers look great along the fence. Known varieties: it is distinguished by the saturated pink color “Lady Hindlip”, capable of adapting to the extreme conditions “Veilchenkoenigin”.
Bessarabian aster is different from the Italian flower size. The most common varieties: reddish-purple "Rubellus", purple "Cassubicus major".
This is the most numerous group. New England flower is a tall species. It is planted closer to the center of the flower garden or along the fence. Varieties that are popular: lush “Bars Pink”, elegant “Gerberose”.
The new Belgian aster is also in demand. Many colors appear on it, so often leaves are not visible. Famous varieties: the pyramidal plant “Amethyst”, “Ballatd” is distinguished by bright inflorescences.
Bush aster looks great in the garden. Popular varieties of this species: semi-double inflorescences “Alba flora of captivity”, lilac-blue “Blue bird”, dwarf type “Venus”.
Preparing the plant for planting
It should choose the right place for growing flowers. To get a gorgeous bush, it is better to choose a sunny area. Receiving lush flowers is possible in good light.
If you plan to grow several varieties, the planting of asters is carried out in accordance with the height of the plants. It is necessary to choose varieties so that they do not shade each other and look harmoniously on the site designated for them. For framing the paths in the garden choose undersized compact varieties.
This flower loves loose soil, in the process of its growth necessarily make fertilizer. They will provide a lush bloom. The soil should pass moisture well. If there is stagnation of water, then the growth of asters will slow down. Gardeners dig up the soil, make fertilizer to prepare a place for the plant.
Planting perennial asters
It is better to plant the plant in spring days, acquire seeds or seedlings in specialized outlets. The flower also propagates by cutting, dividing the bush. Seed planted aster alpine, for other types of this method is not suitable.
Sowing seeds in the fall, but it is better to choose for this spring, when the sun's rays warm the soil. In the fall, the plants are transplanted to a plot chosen in the garden. They need care: in a timely manner to loosen, fertilize the soil. They need good watering.
Growing from cuttings
For the reproduction of plants are prepared in the spring with the onset of the warm season, when the first shoots appear. Cutting is the most common way of growing asters. To do this, cut the tops of plants.
The lower cut is performed obliquely. Before planting, cuttings are kept in water or used for these purposes as a growth stimulator. Then the plants are placed in the penumbra, they root in just 1 month. The next spring, the flowers are transplanted.
Unpretentious flower also needs attention. It should be carried out constant watering, in a dry period, the amount of water increases. It is necessary to remove the weeds growing near asters, it is good to loosen the soil.
Many gardeners use mulch, which helps retain moisture and slows the growth of weeds. Be sure to feed the flowers with fertilizer. Some types of flowers require extra care.
Shrubs are pruned to form a beautiful crown. For tall asters, they use props, plant them along the hedge. Astra is not afraid of cold weather, but before winter it is necessary to cut the stems, cover the ground around it with fallen leaves.
The plant suffers from powdery mildew and gray rot, which are caused by adverse weather conditions or poor care. To protect the flower from disease, it is treated with a special compound.
