Rudbeckia takes pride of place in the flower beds of personal plots due to its bright color. This plant is great in combination with other crops, which is often used in floral arrangements. It has annual and perennial varieties. Rudbeckia belongs to tall crops and can reach a height of three meters. The stem of the flower is straight, can branch. The leaf size of rudbeckia ranges from 5 to 25 centimeters. Its shape is oval or ovoid. Rudbeckia buds are large and reach a diameter of 15 centimeters. The petals, collected in the middle of the flower, are colored in a dark shade and have the shape of a tube. The petals are lighter along the edges, have a lingual shape.

Choosing a place for planting rudbeckia
Rudbeckia prefers bright light, but can also grow in partial shade. When choosing a flower bed for planting rudbeckia, it is important to make sure that no shadow emanating from buildings or from nearby crowns of large trees falls on it. The best option would be a place where the sun shines on the plant for at least six hours a day. This crop loves clay, well-fertilized soils. Preparing the soil for rudbeckia comes down to removing all weeds and enriching it with a small amount of fertilizer.
Features of planting rudbeckia
For rudbeckia, the most popular and at the same time simple planting method is sowing seeds in open ground. This landing occurs in the middle of summer. For planting, small grooves are made in the ground, into which seeds are poured. They are sprinkled on top with a thin layer of soil and sprayed with a spray bottle.After planting, the first shoots can be expected in the fall. By the next season, the grown bushes will be able to delight the eye with bright buds.
Rudbeckia can sprout perfectly even when planted by self-sowing. In this case, it forms dense thickets.
Reproduction of rudbeckia
Seed breeding method of rudbeckia
The simplest and most popular breeding method for rudbeckia is considered to be sowing seeds. Seed material is not difficult to buy, since it is available in almost every flower shop, and is also sold in the markets. Those flower growers who have previously grown this crop on their site may well prepare seeds on their own. When propagating rudbeckia by seeds, it is important to determine the time of sowing them for seedlings. As a rule, seeds are sown in the ground in the second decade of April. However, much will depend on the region.
The process of growing rudbeckia seedlings consists of the following stages: ✿ First, prepare the containers and fill them with nutritious soil.
✿ In containers filled with soil mixture, shallow grooves should be made on the surface, pouring seeds into them. The approximate distance between these grooves will be ten centimeters.
✿ Sprinkle the sown seeds with a small layer of soil and moisten the soil. It is best to use a spray bottle to moisturize.
✿ The containers are covered with glass or foil and placed in a warm place.
✿ The film must be removed regularly to ensure air access and regular watering.
If all the conditions are met correctly, then young shoots will not be long in coming and will break through the soil in an average of two weeks.
After the seedlings grow up, they should be transferred to a permanent flower bed, while you need to be sure that frosts are not expected in the coming months.
For a better survival of the seedlings in a new place, they are hardened. For this purpose, containers with shoots are taken out daily to fresh air, leaving them for several hours. This procedure should be done two weeks before the intended planting of seedlings in the flower bed.
When transplanting seedlings to a permanent place of growth, it is necessary to maintain a distance between the plants. The distance between them should be at least half a meter. You should also not plant the bushes too far.
Propagation of rudbeckia by dividing the root
Another way of reproduction of rudbeckia is the division of its root. This procedure is carried out in the first days of spring. The bush of the plant must be completely dug out of the ground and divided into several fragments, so that a bud of renewal remains on each of them.
It is necessary to prepare the soil, for this it is loosened and mixed with fertilizers. Depressions are made in the ground in the form of holes, in each of which a fragment of a bush is planted.
The root division method is also used to rejuvenate old bushes. This is due to the fact that the average lifespan of rudbeckia is five years. Rejuvenation is recommended every four years.
Rudbeckia care
This plant is not whimsical. It will take root well in a new place, it tolerates dry periods well and grows quickly. In order to observe a lush and bright flower bed on your site, on which the rudbeckia will be the queen, it is necessary to provide her with basic living conditions, which include: regular and moderate moisture, especially during the period of active growth, when the rudbeckia bushes increase their green mass, several planned dressings, pruning the plant and preparing it for winter. In addition, most varieties of rudbeckia are tall, so it is recommended to tie up too long stems to supports.
Fertilizing rudbeckia
Rudbeckia needs several planned dressings, namely, two times per season, special fertilizers for flowering plants can be applied to the soil. The first time fertilizers are applied during the growth of the plant.The second time, the bushes are fed during the stage of ovary formation. For these purposes, the fertilizer is dissolved in water and applied to the soil together with watering the rudbeckia.
Pruning rudbeckia
Pruning is carried out in order to extend the flowering period of the buds, thereby preserving the decorative effect of the flower bed. Annual varieties are pruned throughout the flowering season by removing dead buds and stems. Perennial crops are thinned out not only during the flowering period, but also in the fall to prepare the bushes for winter.
Winter care for rudbeckia
Perennial rudbeckia with the onset of cold weather should be cut at the root and covered with foil. On top of the film, you need to lay foliage, hay or spruce branches.
Rudbeckia - diseases and pests
The risks of developing diseases in rudbeckia when grown in good conditions are practically zero. However, there are some pests and diseases that can damage this plant in all conditions.
If brown spots are seen on the leaves of rudbeckia, this indicates a defeat leaf nematodes... You can get rid of them by applying insecticides. These drugs will also help combat aphids, caterpillars and garden mite.
Powdery mildew manifests itself as a white bloom on rudbeckia foliage. It is possible to eliminate it with special compounds that contain sulfur.
If the foliage appeared rust, then a fungicide solution will help to cope with it.
Rudbeckia varieties
Today there are more than forty types of rudbeckia. Only eight beautiful varieties are used as a garden plant:
Rudbeckia brilliant
Rudbeckia "Goldilox"
Rudbeckia is beautiful
Rudbeckia "Marmalade"
Rudbeckia purpurea
Rudbeckia hairy
Golden ball

A wonderful flower bed decoration, which will delight more than one year, is hidden behind the orange-variegated rudbeckia petals. It is unpretentious in care, blooms all summer until the frost, and next to companions gives an excellent color composition. Loved by flower growers for its charm and ease of growing.
Origin and climatic requirements
In natural conditions, the flower is found in central North America, where there is enough sun, and there are sources of moisture nearby. The plant got its name thanks to the botanist researcher Olof Rudbek. His botanical journey gave the world a golden flower, and further research led to the achievement of 40 varieties of rudbeck.
It feels best in open sunny places, but does not tolerate the lack of moisture, this should be taken into account when planting. In dry summer, the flower needs regular abundant watering, otherwise the leaves begin to curl, and the flowering is not so abundant. The temperature regime corresponds to the temperate climatic zone: growth conditions are favorable in central Russia.
According to the botanical classification, the plant belongs to the Aster family (similar in structure and shape of seeds), and the genus is rudbeck. Americans call the flower "Black-Eyed Suzanne" for its dark, well-defined convex core. The Russian popular name sounds like "Sun Hat", so named due to the bright yellow halo of petals.
Description of rudbeckia
Rudbeckia in a flowerbed can be seen from afar: long stems with yellow black-eyed flowers attract the eye. Perennial species grow from 50 cm, this length is enough both for cutting and for background decoration of low-growing bushes. Under favorable conditions, some varieties can grow up to 2 m, but such bushes require additional support due to their thin fragile stem.
The color range of petals ranges from yellow to red-brown, there are monochromatic and variegated varieties. The petals are elongated, feather-shaped, collected in an even calyx, which surrounds a dark tuberous core - the seed box. The inflorescence grows up to 15 cm in diameter, on one bush there can be several peduncles with flowers of different diameters.
The stem is erect, herbaceous in tall varieties, bends towards the ground. Some varieties form a branched stem, which can be achieved by simply pinching 3 leaves in the growth phase. There are not many leaves, they are distributed in pairs along the stem. The shape of the leaf plate is oblong, ovoid with notches along the edge. There are varieties with narrow-lanceolate and dissected leaves.
The root system of a rhizome type with a thick root and small hairy processes. It fills the entire space and therefore requires thinning for normal growth. It can propagate both by seeds and by the rhizome of perennial species.
Growing rudbeckia from seeds When to plant
Planting a plant by seed method is not particularly troublesome, you can germinate seeds both in a flower bed and in a seedling method at home or in a greenhouse. Suitable for different climatic zones. Seeds of hybrid varieties do not propagate by self-sowing, and self-collected seeds from such bushes will not give the original beauty.
Seedless method: sowing in open ground
Planting rudbeckia seeds will not bloom in the first year, but next summer the flower will bloom earlier than its seedlings. Seeds are sown on a flower bed even in March, if only the soil is ripe for mechanical processing. The seeds are not afraid of frost, so even sowing rudbeckia in the winter is possible. For everything to go well, it is necessary to sow in cold weather, late October - early November, when already warm days will not force the plants to rise and die from frost. The garden bed should simply be mulched with a layer of humus 2-3 cm.
For rudbeckia, a slightly acidic, fertile soil is prepared, mineral and organic fertilizers are applied, mulch for good aeration. Clay soils are diluted with sandstone and compost, which provides air permeability to the soil, relieves roots from decay.
- Sowing is carried out shallowly, to a depth of about 1-2 cm. For this, shallow furrows are prepared with a flat cutter or a small hoe, sowing is carried out as rarely as possible and the furrows are closed with the back of the rake.
- The distance between the rows is 25-30 cm.
- Water it sparingly, so as not to get a continuous puddle, from the drying of which an earthen crust with cracks is formed. Better less and more often than plentiful, but occasionally.
- When the plants sprout, weeding is imperative. They remove not only weeds, but also extra, weaker, shoots of the rudbeckia itself. Excessive density will adversely affect the condition of young plants, leading to their stretching and fragility. Do not spare extra flowers!
Young plants of rudbeckia should grow at a distance of 10-15 cm, this is enough to survive the first year, form a root system, and build up green mass. At the end of summer, flowers are transplanted at a distance of 50-60 cm so that the overgrown branchy bushes do not interfere with each other.
Seedling method
Sowing rudbeckia for seedlings begins in late February - early March.
- Seeds are planted one or two in seedling containers with a nutrient substrate, covered with a small layer of earth.
- So that the seedlings are not washed out, they are sprayed from a fine spray bottle with settled or spring water at room temperature.
- For germination, seeds need a temperature of at least 22 ºС: otherwise growth will slow down, but high temperatures will nevertheless elongate the stems of the sprouts, making them threadlike and weak.
- Seedlings do not tolerate severe waterlogging, otherwise rot diseases will develop, for example, black leg.
Advice! It is better to take the land for seedlings from the flower bed where the rudbeckia will grow constantly.
If sowed in rows in a common container, you will have to dive. In the phase of 2-3 true leaves, the seedlings are dived into individual seedling glasses.
They begin to harden at the beginning of May, so that by the 20th the seedlings are already accustomed to the open air. They are planted in the ground at positive night temperatures at a distance of 50-60 cm.
When and how to plant rudbeckia seedlings in open ground
You can plant seedlings after the threat of spring frosts, the period depends on the region and climatic conditions. Before landing, it is worth checking the long-term weather forecast to make sure there are no low night temperatures. And the threat of frost can be avoided by covering young sprouts with covering material or film. After rooting, perennials are not afraid of low temperatures, they perfectly tolerate a short-term decrease to -5 ° C.
The planting scheme depends on the type and variety of the flower: the undersized have enough light and heat at a distance of 30-40 cm, and it is better to plant tall ones farther from each other - up to 70 cm.This distance will allow growing large, abundantly flowering plants.
The soil is prepared from an organic substrate, chernozem and sandstone; if desired, a mineral-organic complex is added. The planting depth of the bush should be the same as in the seedling container. A deeper hole will negatively affect growth, the flower may die from rotting of the root part of the stem.
Advice! For warmth and nutrition, a 10 cm layer of compost or cut grass is placed under the root system. Such a "stock" is useful for a perennial growing without transplanting in one place for a long time, and you will not need to worry about feeding for flowers once again.
When to transplant rudbeckia
After 3-5 years of growth in one place, the plant needs to be thinned, otherwise decorative properties decrease, flowers become smaller, there is not enough space for new bushes to develop. Self-seeding gives a lot of unnecessary daughter shrubs, so it is better to keep the flower bed in its original form, providing the necessary conditions for development.
An adult bush is transplanted to a new location in early spring or late summer.when there is no active vegetation. It is advisable to divide the bush to give new room for plant growth. This will turn on the regenerative mode, and the flowering will be more abundant.
Reproduction of rudbeckia by dividing the bush
Getting new seedlings from an old rudbeckia bush is as easy as shelling pears. It is enough to carefully dig out the rhizome and divide it with a shovel. The finished cut is placed in a new place in a separate well, each having been spilled with water.
The rhizome must be pest-free, healthy in appearance, otherwise the diseases of the old bush will be transmitted to a new place. Before planting, you can dip the root in a weak solution of manganese to disinfect and protect it from pests.
Advice! Mature bushes more than 5 years old react more strongly to weather changes, so regular transplanting is necessary to save the bush.
Difficulties in growing rudbeckia
Despite its unpretentiousness, the plant needs care: loosening the compacted soil, applying fertilizers, watering if necessary. Lack of proper care, weed infestation of the flower bed will make the flower vulnerable to diseases and pests.
- Powdery mildew manifests itself as a white bloom on the ground near the flower, it is treated with a solution of copper sulfate (80 g per 10 liters).
- The nematoda is noticeable by brown spots on the leaves.Perennial varieties are treated with Nemagon or Bazamid, one-two-year-old species are simply removed, and the flower bed is treated with antiseptics.
- Caterpillars, other insects gnaw stems and green mass. Pests are destroyed by insecticides.
After flowering, the buds are cut to continue flowering profusely. Finished seeds are harvested from the middle of a pre-dried flower.
Perennial varieties do not need additional shelter for the winter, but you can sprinkle them with fallen leaves or spruce branches. Before wintering, the entire ground part is cut off.
Rudbeckia and Echinacea: What's the Difference?
Initially, the two plants belonged to the same Rudbeky family, but in the 19th century. botanist Minh divided them, isolating echinacea as a separate genus. Outwardly, they are similar in structure, abundant flowering, habitat and climatic conditions for growing. Distinctive qualities that made it possible to separate echinacea into a separate genus:
- color range (rudbeckia has a yellow-orange-brown color, echinacea is purple-pink);
- healing properties (echinacea has useful qualities, rudbeckia is devoid of this);
- the structure of the bract (in Echinacea it is prickly, which was the name of the flower).
Rudbeckia in landscape design
Designers fell in love with the flower for its species and varietal diversity, the versatile possibility of growing both on the sunny side and in shaded areas.
Tall bushes look great next to the fence, hide the secret places of the garden, form a hedge in the labyrinth of the park area.
For low-growing species, a place is reserved among multi-level borders, single flower beds design. Some varieties can be used for terrace potting.
As a companion for rudbeckia in a flower bed, they use:
- garden chamomile,
- cereals, echinacea,
- asters and chrysanthemums,
- monard.
Their structure and growing conditions are the same, so there will be no conflict, but only a harmonious balance.
Rudbeckia will thank the caring gardener with her charm, her flowers will delight for a long time, both in the flowerbed and in the cut.
Varieties and varieties of rudbeckia with photo and name
In total, about 40 species have been bred, each of which has its own varietal range. Breeders do not stop there, creating new varieties, improving the protective properties, color, climatic adaptability of the plant. Known hybrid varieties that are more stress resistance to changing climatic conditions.
Rudbeckia hairy Rudbeckia hirta
Known for perennial and annual varieties, the cultivation of which depends on the natural growing conditions. Northern regions where winters are harsh can be grown as an annual, while in areas with mild winters it can be grown as biennial or perennial.
It grows up to a meter in height with a simple or branched stem, often lowered due to wind and rain pressure. The leaf mass consists of sessile, large, oval-shaped leaf plates, the edge of which is strongly serrated, but not traumatic. The flower-bearing basket consists of ligulate and tubular petals, usually yellow, with a gray-brown core.
Medium and undersized varieties are popular:
- Marmalade,
- Indian summer,
- Goldstrum (up to 60 cm),
- Goldflamme (25 cm).
These look great in a mix with asters and other bright flowers in the same flower bed. Inflorescences are medium-sized, up to 10 cm in diameter, more often of a simple structure.
Rudbeckia grasping Rudbeckia amplexicaulis
It differs in its size - it grows up to 80 cm, but does not require additional stem support. Leaves are smooth, elongated, bright green, rarely planted, there are small notches at the edges. They have a sunny yellow inflorescence, the center of which is often dark brown, but there are varieties with a maroon core. The petals are omitted, they "clasp" the stem from above, that is why it got its name. Grown as an annual plant, it can multiply by self-sowing.
Rudbeckia bicolor rudbeckia bicolor
It grows up to 70 cm, looks good in mixborders, flower pots, can become a background for a multi-level flower bed. The receptacle is high - up to 2 cm, the color range is not diverse (yellow and orange shades of reed petals and almost black tubular centers). The diameter of the inflorescence is up to 8 cm, the first flowers are larger than the subsequent ones. With sufficient moisture, it blooms profusely.
Rudbeckia lustrous or radiant Rudbeckia fulgida
The species got its name from the shape of the inflorescence with bright petals in the form of rays emanating from a dark center. It grows up to 60 cm, and more often even lower, it belongs to perennial plants. It can grow in one place for up to 5 years, in the future it requires transplantation or thinning. The petals are ligulate, with a slight radial ribbing. The leaf plate is wide, bright, dark green.
Massively grown 2 varieties:
- Goldstroom,
- Goldstar.
Rudbeckia triloba Rudbeckia triloba
The shortest flowering plant of its kind: the flowering period lasts about a month. A thin, flexible stem reaches 1 m. The green mass is not uniform: the basal rosette is three-lobed, and oval leaves are rarely planted along the stem. At the top of a simple peduncle rises a yellow hat with short petals and a tubular hemispherical core.
They are used as decoration for wild-growing parks, coastal areas of artificial reservoirs.
Occidental rudbeckia Rudbeckia occidentalis
Has gained attention with its cone-shaped flower, on which reed petals are completely absent. Inflorescences consist of tubular petals and green bracts on a long peduncle. This type was named among florists "Black Beauty", which are used to create bouquet compositions. The flower has become known to the Russian public since 2002, when floristic art became widespread.
Rudbeckia dissected Rudbeckia laciniata
One of the tall species representatives, the size of which reaches 2 m. The inflorescences are spherical, with a green tubular core. Due to the high stem, the plant is often deformed, tilts to the ground under the pressure of heavy rainfall and winds. Pruning, thinning helps to avoid this.
A popular variety is the Golden Ball, which has a spherical petal inflorescence up to 10 cm.
Rudbeckia lustrous Rudbeckia nitida
The tall plant reaches 2 m, the flower is large, up to 12 cm in diameter. The petals are bright yellow, smooth, arranged in a circle that stands out 2 cm upwards. Green tubular petals are located in the center. Popular varieties for mass breeding Herbston, Goldshire differ in the shape of the inflorescence, a shade of yellow.
Giant rudbeckia Rudbeckia maxima
The tall plant is distinguished by resistance to weather conditions: it feels great in dry summers and during spring-autumn frosts. It does not lose its aesthetics in cutting for a long time, therefore it is loved by florists. The yellow inflorescences consist of a few petals that surround a maroon center of tubular petals.
Rudbeckia hybrid Rudbeckia hybrida
It has the properties of several species representatives at once, it is displayed specifically for the conditions of a particular locality or region.To create a new variety, a glossy, dissected, hairy rudbeckia is used.
Hybrid varieties are characterized by large inflorescences, up to 19 cm, with long yellow-brown reed petals up to 14 cm. Tubular petals form a purple core. The varieties known to the public Gloriosa Daisy, Double Daisy are distinguished by high bushiness, large inflorescences with a variegated or monochromatic color scheme.
White swan is one of the outstanding varieties of rudbeckia with boiling white inflorescences similar to swan plumage. The petals are pulled down from the greenish-yellow spherical core. Suitable for growing in northern climates, where the average daily temperature in summer fluctuates around 15-25 ºС.
Rudbeckia fine or beautiful Rudbeckia speciosa
Low bushes up to 50-60 cm in height are covered with a scattering of large, up to 10 cm in diameter, flowers. The edges of the petals are serrated, having three stripes-reeds, the petals are rich orange, the centers are lilac-violet, almost black. The leaves are elongated, slightly rounded closer to the base.
In order for the flower garden to always have a well-groomed appearance with minimal effort on the part of the gardener, it is enough to plant such a perennial as rudbeckia. Planting and caring for a plant takes a few minutes, and a flower grows in one place for many years.
Description of rudbeckia: varieties and varieties
Rudbeckia has about four dozen varieties. Each has its own characteristics of the structure of the flower.
But most are united by the presence of bright yellow petals in the color:
- Rudbeckia dissected - is the highest representative of the genus. It can reach a mark of 2 m and more. Flowering lasts from July until the first persistent frost. There are varieties with simple and double flowers.
- Hybrid rudbeckia is a medium-sized variety, peduncle length up to 70 cm. It is distinguished by a dark brown convex center. The flowering period is the second half of summer.
- Rudbeckia bicolor - the average height of these varieties is from 25 to 50 cm. An interesting feature is the color of the petal - bright red at the base and yellow from the middle to the tip.
Planting a plant
They start planting rudbeckia in the open field in the last decade of May. A perennial is assigned a plot with well-cultivated soil in a sunny place. The soil must first be filled with compost.
Important. The mechanical composition of the soil for rudbeckia is preferable to be moderately loose. Breeding will not be successful on heavy soils. Sand should be added to clay soil for digging.
When sowing seeds in open ground, depending on the variety, a distance of 15 to 40 cm is left between the plants. This method will ensure the emergence of seedlings by the middle of summer. The first flowering can be expected only next year. In one place, rudbeckia will grow for about 5 years.
To see the buds earlier, they practice propagation through seedlings. For this, the sowing of seeds is carried out in greenhouse conditions in April. This method will protect delicate seedlings from spring frosts and other vagaries of the weather. For this:
- Crops are carried out in containers with a nutrient substrate, covered with glass and kept at a temperature of at least + 21 ° C.
- Caring for them consists in moistening by spraying with water and ventilating.
- When two true leaves are formed, a pick is made into separate pots with a larger feeding area.
Planting seedlings in a flower bed is carried out when the danger of unexpected frosts has passed.
Plant care
Even a beginner in floriculture can handle the care of rudbeckia. All that is required of the gardener is to periodically loosen the soil and water. It is a hardy plant that tolerates short-term droughts.
Advice. Perennial does not require the formation of a bush.During the growing season, it is only occasionally recommended to prune - and only out-of-date inflorescences. This care stimulates further bud formation.
With the arrival of the autumn cold, the dried stems are cut off. For the winter, the flower bed is mulched with humus or cut grass.
Fertilizing and feeding rudbeckia
Growing rudbeckia in the open field must be supported by top dressing. Fertilization of plantings is performed twice a season:
- At the beginning of the growing season, fertilizing is carried out with a complex mineral fertilizer.
- After three weeks, fertilization is carried out with a solution of nitrophoska and potassium sulfate - 1 tbsp each. l. on a bucket of water.
For better assimilation of dressings, the soil is loosened and the flower beds are irrigated at the same time.
Reproduction of rudbeckia
It is recommended to grow rudbeckia in one place for no more than 6 years. At this age, perennial reproduction is practiced by dividing the bush.
Important. This procedure is performed before the active growing season begins - in early spring. Also, the division of the bush is performed after the flower leaves for a dormant period - in the fall.
The dividing technique is very simple. The bush is dug up and the rhizome is carefully divided into several parts. The damaged areas are cut with a sharp knife. After that, flowers are placed in a new place.
Diseases and pests
Growing rudbeckia is beneficial in that it is less likely to be affected by diseases than other ornamental perennial plants. However, under unfavorable conditions, flowers may develop:
- powdery mildew - manifests itself as a white bloom on the leaves, which quickly spreads over the plate;
- Rust - Symptoms are many small orange blisters on leaves and stems.
These diseases are fungal in nature. Caring for such plants consists in treating with fungicides. Spraying with a solution of colloidal sulfur or copper sulfate will help.
Other pests that parasitize rudbeckia include leaf nematodes. Their appearance and reproduction is facilitated by improper care of flowers, in particular, excessive watering. The presence of the nematode becomes noticeable when there is no chance to save the rudbeckia, so the affected specimens will have to be removed from the flower bed.
Perennial rudbeckia: combination with other plants
The combination of rudbeckia in landscape design with other light-loving flowers: Turkish carnations, alpine aster, bells will be successful. It should be borne in mind that tall varieties with improper planting in open ground relative to the cardinal points can shade neighboring plants.
Therefore, the scheme of flower beds with rudbeckia is planned so that during the day they themselves are not in the shade and do not block the sun for other plants.
At the same time, if shade-tolerant plants are planned to be planted on the mixborder next to the rudbeckia, the latter must be placed with an orientation to the north side. With this combination, rudbeckia will act as a natural barrier for those flowers that are harmed by direct sunlight.
Perennial rudbeckia in landscape design
In landscape design, perennial rudbeckia is indispensable when arranging mixborders. Tall varieties are placed in the background or closer to the center of the flower bed. This arrangement allows you to cover the bare stems of perennials with other, lower flowers.
They also practice the cultivation of low-growing varieties with lush foliage along the edge of the flower garden. This technique will decorate the flowerbed with a living border from the plantings of rudbeckia.
Do not limit yourself to single plantings of rudbeckia in the open field. The expressive color of perennial petals must be emphasized by the neighborhood of other bright colors. This works best in landscaping, which is designed with a laid-back, rustic feel.
Growing rudbeckia is an easy and enjoyable job.A perennial grows quickly and requires a minimum of the participation of a grower. And at the same time it has high decorative qualities.
Perennial rudbeckia, planting and care (video)
Hello! Rudbeckia - planting and care, growing in the open field in our material. Rudbeckia takes pride of place in the flower beds of personal plots due to its bright color. This plant is great in combination with other crops, which is often used in floral arrangements.
It has annual and perennial varieties. Rudbeckia belongs to tall crops and can reach a height of three meters. The stem of the flower is straight, can branch.
The leaf size of rudbeckia ranges from 5 to 25 centimeters. Its shape is oval or ovoid. Rudbeckia buds are large and reach a diameter of 15 centimeters.
The petals, collected in the middle of the flower, are colored in a dark shade and have the shape of a tube. The petals are lighter at the edges, have a lingual shape.
Rudbeckia perennial planting
Choosing a place for planting rudbeckia
Rudbeckia prefers bright light, but can also grow in partial shade. When choosing a flower bed for planting rudbeckia, it is important to make sure that no shadow emanating from buildings or from nearby crowns of large trees falls on it.
The best option would be a place where the sun shines on the plant for at least six hours a day. This culture loves clay, well-fertilized soils.
Preparing the soil for rudbeckia comes down to removing all weeds and enriching it with a small amount of fertilizer.
Features of planting rudbeckia
For rudbeckia, the most popular and at the same time simple planting method is sowing seeds in open ground. This landing occurs in the middle of summer.
For planting, small grooves are made in the ground, into which the seeds are poured. They are sprinkled on top with a thin layer of soil and sprayed with a spray bottle.
After planting, the first shoots can be expected in the fall. By the next season, the grown bushes will be able to delight the eye with bright buds.
Rudbeckia can sprout perfectly even when planted by self-sowing. In this case, it forms dense thickets.
Reproduction of rudbeckia
Seed breeding method of rudbeckia
The simplest and most popular breeding method for rudbeckia is considered to be sowing seeds. Seed material is not difficult to buy, since it is available in almost every flower shop, and is also sold in the markets.
Those flower growers who have previously grown this crop on their site may well prepare seeds on their own.
When propagating rudbeckia by seeds, it is important to determine the time of sowing them for seedlings. As a rule, seeds are sown in the ground in the second decade of April. However, much will depend on the region.
The process of growing rudbeckia seedlings consists of the following stages:
- ✿ First, prepare the containers and fill them with nutritious soil.
- ✿ In containers filled with soil mixture, shallow grooves should be made on the surface, pouring seeds into them. The approximate distance between these grooves will be ten centimeters.
- ✿ Sprinkle the sown seeds with a small layer of soil and moisten the soil. It is best to use a spray bottle to moisturize.
- ✿ The containers are covered with glass or foil and placed in a warm place.
- ✿ The film must be removed regularly to ensure air access and regular watering.
If all the conditions are met correctly, then young shoots will not be long in coming and will break through the soil in an average of two weeks.
After the seedlings grow up, they should be transferred to a permanent flower bed, while you need to be sure that frosts are not expected in the coming months.
For better survival of the seedlings in a new place, they are hardened. For this purpose, containers with shoots are taken out daily to fresh air, leaving them for several hours.This procedure should be done two weeks before the intended planting of seedlings in the flower bed.
When transplanting seedlings to a permanent place of growth, it is necessary to maintain a distance between the plants. The distance between them should be at least half a meter. You should also not plant the bushes too far.
Propagation of rudbeckia by dividing the root
Another way of reproduction of rudbeckia is the division of its root. This procedure is carried out in the first days of spring. The bush of the plant must be completely dug out of the ground and divided into several fragments, so that a bud of renewal remains on each of them.
It is necessary to prepare the soil, for this it is loosened and mixed with fertilizers. Depressions are made in the ground in the form of holes, in each of which a fragment of a bush is planted.
The root division method is also used to rejuvenate old bushes. This is due to the fact that the average lifespan of rudbeckia is five years. Rejuvenation is recommended every four years.
Rudbeckia care
This plant is not whimsical. It will take root well in a new place, it tolerates dry periods well and grows quickly.
In order to observe a lush and bright flower bed on your site, on which the rudbeckia will be the queen, it is necessary to provide her with basic living conditions, which include: regular and moderate moisture, especially during the period of active growth, when the rudbeckia bushes increase their green mass, several planned dressings, pruning the plant and preparing it for winter.
In addition, most varieties of rudbeckia are tall, so it is recommended to tie up too long stems to supports.
Fertilizing rudbeckia
Rudbeckia need several planned dressings, namely, two times per season, special fertilizers for flowering plants can be applied to the soil. The first time fertilizers are applied during the growth of the plant. The second time, the bushes are fed during the stage of ovary formation. For these purposes, the fertilizer is dissolved in water and applied to the soil together with watering the rudbeckia.
Pruning rudbeckia
Pruning is carried out in order to extend the flowering period of the buds, thereby preserving the decorative effect of the flower bed. Annual varieties are pruned throughout the flowering season by removing dead buds and stems. Perennial crops are thinned out not only during the flowering period, but also in the fall to prepare the bushes for winter.
Winter care for rudbeckia
Perennial rudbeckia with the onset of cold weather should be cut at the root and covered with foil. On top of the film, you need to lay foliage, hay or spruce branches.
