Rudbeckia (yellow daisy) - growing in a personal plot. Rudbeckia - perennial and annual species Rudbeckia species and varieties

21.03.2024

Almost every gardener has Rudbeckia. There are perennial and annual rudbeckia. See what types they include to choose for a specific place in the flower bed or garden.

This plant has about 30 species in the genus, among which there are more than 400 varieties, depending on which the flowers are tall and short.

This type of perennial is represented by the variety "Goldstorm" with golden yellow flowers and black centers. Its petals are arranged in one row and resemble in shape our cultivated large chamomile. The black core is pronounced and convex, like that of Echinacea. The flower size reaches up to 12 cm in diameter. This lush bushy plant reaches a height of 70 cm and blooms from July to September. Looks great both in the background of a flower bed and alone.

Dissected Rudbeckia (‘Rudbeckia Laciniata’)

We also call it "Golden balls". Quite large golden yellow flowers with many petals and brown centers. Blooms from July to September. This perennial plant can reach a height of two meters, and the diameter of the spherical inflorescences reaches 10 cm.

It has many varieties, of which the most popular are 'Goldball', from which the name took root in the Russian language, and another subspecies of it ‘Golduelle’. The latter variety is distinguished by its relatively small height - up to 80 cm, as well as the color of the cores - bright green.

Variety "Herbstone" is a hybrid with large double flowers and tall stems reaching 1.70 m. The combination of golden-yellow petals and a bright green center looks original and attractive. Blooms from July to September.

The latest of the varieties is ‘Rudbeckia subtomentosa’, height from 1.20 to 1.50 m. The well-branched bush bears dozens of large inflorescences. The marginal petals are bright yellow, the cone is reddish-brown. The petals of this rudbeckia are, as it were, rolled into a tube and arranged in one row. Resembles an aster with thin petals. It begins to bloom from the beginning of August and lasts until severe frosts.

Rudbeckia enveloping

‘Amplexicaulis’. This species belongs to medium-sized plants - straight and branched branches reach 60 cm. Large yellow baskets with a purple-red tint at the base, together with dark brown cones of the cores, look very impressive. This variety blooms for the longest time - from June to October.

Rudbeckia hairy

Hirta relatively low among its fellow annuals: 30 - 60 cm. It is distinguished by branched stems and spear-shaped leaves. The basket color transitions from a golden yellow edge to a brown center. This variety is not afraid of frost and blooms until October inclusive.

'Goldilocks'– terry version of “hairy”. Height up to 60 cm, with large semi-double and double flowers of yellow gold with a large black core. The basket reaches 10 cm in diameter. Wide petals with rounded edges are arranged in one row, but very closely, and they seem to make up two or three rows.

‘Becky Mix'- this is a dwarf plant up to 25 cm high, but with a rather large flower basket - up to 15 cm. The color of the petals from the edges starts from bright yellow, turns into orange and ends with a black core. Blooms until frost.

"Toto", probably the smallest of all the popular varieties, barely reaching 20 cm in height, with fairly wide dark green foliage. However, its inflorescences are large and look very unusual on a short plant. By the way, the variety blooms well in containers.

Rudbeckia perennial is most often used in our country. Although among the annuals there are very beautiful and unpretentious ones. They are most interesting in regions with particularly cold climates, where perennial flowers practically do not survive.

Plant rudbeckia (lat. Rudbeckia) belongs to the genus of herbaceous annuals, biennials and perennials of the Asteraceae family, which includes about forty species. In nature, rudbeckia flowers are distributed mainly in the prairies of North America; in culture they are grown mostly in Europe and Africa. The first settlers to North America called rudbeckia “black-eyed Susan” because of the dark center of the inflorescence, but Europeans thought that “sunhat” was a better name for the plant. The scientific name was given to Rudbeckia by Carl Linnaeus in honor of the Swedish botanists, the father and son Rudbecks, the younger of whom was Linnaeus's friend and teacher, as well as the great-great-great-grandfather of Alfred Nobel, and was famous for his discovery of the human lymphatic system in 1653.

Rudbeckia flowers - description

The rudbeckia flower has simple or branched, rigidly pubescent stems, reaching a height of half a meter to 200 cm, although some wild species grow up to three meters. The leaves of rudbeckia are entire, pinnately dissected or pinnately divided, oval or ovoid, from five to twenty centimeters long, in the lower part of the stem on long petioles, in the upper part - sessile. Inflorescences-baskets up to 15 cm in diameter consist of marginal sterile reed flowers of different shades of yellow and middle bisexual tubular flowers, painted in various colors - from yellow to brown or purple-black. The rudbeckia fruit is an oblong achene, sometimes with a small crown. Shiny, small, dark gray rudbeckia seeds remain viable for 2-3 years.

Growing rudbeckia from seeds

Sowing rudbeckia

All species and varieties of rudbeckia, except double varieties, reproduce generatively, and only perennial species can also be propagated by dividing the rhizome. If you don't want to bother with seedlings, you can sow the seeds directly into the ground. They do this in the middle or end of June: sow the seeds on prepared beds at a distance of about 15 cm from one another and sprinkle a thin layer of earth on top, then sprinkle the crops generously with water. By autumn, small rosettes of leaves will appear in the garden bed, which next year will develop into lush bushes and bloom before the rudbeckias planted in the spring. Rudbeckia in the garden also reproduces by self-sowing, and if you do not fight this phenomenon, but simply thin out the seedlings that appear from under the ground in the spring, then you don’t have to resort to seed propagation, relying on the wise nature.

Rudbeckia seedlings

Propagation of annual and perennial rudbeckia by seedlings begins in late March or early April by sowing the seeds in seedling boxes, sprinkling them with a thin layer of soil and lightly sprinkling the sowing with water from a sprayer. Under the film and at a temperature of 20-22 ºC, seedlings appear in one to two weeks. All this time, you need to moisten the soil in the boxes as necessary, remove condensation from the film and ventilate the crops. When two pairs of leaves appear, the seedlings are planted more spaciously so that they do not interfere with each other’s growth, and after they have become comfortable, they begin to harden them, taking them out to the balcony or terrace every day for several hours.

Planting rudbeckia

When to plant rudbeckia in the ground

Rudbeckia is planted in open ground at the end of May, when the threat of night frosts has passed. Select a sunny area with fertile, permeable, cultivated soil for rudbeckia. You need to add sand to clay soil before digging, but it is advisable to enrich any soil with compost before planting rudbeckia. If part of the site ends up in partial shade, it’s not a big deal; rudbeckia grows well in slightly shaded areas.

How to plant rudbeckia

Rudbeckia is planted in open ground at a distance of 30-40 cm between specimens. If summer has already arrived in your region, rudbeckia will quickly take root, but if spring turns out to be protracted and the nights will be cool, rudbeckia planted in a flowerbed should be covered with agrospan at night until it takes root - after that the plant is not afraid of low temperatures. In one place, perennial rudbeckia grows from 3 to 5 years, so it makes sense to mulch the area after planting with an eight-centimeter layer of compost.

Rudbeckia care

How to care for rudbeckia

Planting and caring for perennial rudbeckia does not contain any subtleties or secrets - everything is as usual: watering regularly, morning or evening, often in the hot season, after watering - loosening the soil in the area while simultaneously removing weeds. Tall species and varieties of rudbeckia need to be tied to supports. At the beginning of the season, rudbeckia is fed with a solution consisting of one tablespoon of nitrophoska, one tablespoon of potassium sulfate and one tablespoon of Agricola-7, dissolved in ten liters of water, taking into account the consumption of 3 liters of solution per 1 m² of area. After two weeks, the same fertilizing is applied again. As the inflorescences wither, they are removed with part of the peduncle up to the top healthy leaf.

Rudbeckia transplant

If rudbeckia grows in one place for more than five years, it produces abundant growth that clogs the area. In this case, the rudbeckia needs to be transplanted to a new location. Dig up a bush, divide it and plant the parts in a new bed, maintaining the required distance between the bushes. It is necessary to divide and replant rudbeckia when it has not yet entered a period of active growth - in early spring or after flowering.

Rudbeckia propagation

We talked about propagating rudbeckia by seed in the chapter “Growing rudbeckia from seeds,” and the method of dividing the bush is described in the previous section. There are no other ways to propagate rudbeckia.

Pests and diseases of rudbeckia

Of the diseases, rudbeckia is extremely rare, but still affected by powdery mildew. It looks like a loose white coating on the above-ground parts of the plant. Spraying rudbeckia with a one percent solution of colloidal sulfur or a solution of copper sulfate at the rate of 80 g per 10 liters of water will help cope with the disease. Sometimes there are cases of oppression of rudbeckia by a leaf nematode, which is expressed by the appearance of brown spots on the leaves, their thinning and death. It is effective to use Bazamid, Nemagon and Nemaphos against nematodes in the manner specified in the instructions; diseased and damaged specimens must be removed from the area. If annual rudbeckia has been affected, burn all its plant remains in the fall, carefully dig up the area and water it with a strong solution of potassium permanganate.

Rudbeckias and leaf-eating insects - larvae and caterpillars - are harmful. However, in general, rudbeckia is a plant that is rarely exposed to diseases and pests, and if planting and caring for rudbeckia is carried out in accordance with the requirements of agricultural technology, then you are unlikely to have problems with its health.

Rudbeckia after flowering

How and when to collect rudbeckia seeds

Rudbeckia blooms and produces seeds in the fall. Wait for the seeds to dry on the flower, then put on gloves and carefully collect the seeds from the center of the flower, scatter them on newspaper and dry in a dry, ventilated area.

Perennial rudbeckia in winter

Perennial rudbeckia needs shelter for the winter, but first you need to cut off the plant debris to the very surface of the soil, and then cover the area with a thick layer of humus (5-7 cm), spruce branches or dry grass.

Types and varieties of rudbeckia

All cultivated species and varieties of rudbeckia are divided into annual (also known as biennial) and perennial. To the most common in culture annual species include:

Rudbeckia hirta

- native to North America, usually grown as an annual or biennial. Its stems are simple or branched, stiffly pubescent, about a meter high. The basal leaves are petiolate, entire, ovate, the stem leaves are alternate, broadly lanceolate, sessile, hairy, with large teeth. On long peduncles there are basket-shaped inflorescences up to 10 cm in diameter. Reed flowers are yellow, tubular, gray-purple, the receptacle is convex. The most commonly used varieties in cultivation are the low-growing varieties Toto Rustic, Goldflamme - up to 35 cm in height; Marmalade, Indian Summer – up to 45 cm high; Goldstrum - up to 60 cm high with simple inflorescences about 10 cm in diameter.

Rudbeckia bicolor

- an erect bushy plant from 25 to 70 cm in height with pubescent stems and lanceolate leaves. Bright inflorescences 6-8 cm in diameter are equipped with two rows of ligulate yellow or orange flowers, sometimes with a purple-black base. Tubular flowers, located on a cylindrical receptacle up to 2 cm high, are almost black in color. Flowering of rudbeckia bicolor begins in mid-June and ends before frost. The most famous variety is Herbstwald - rudbeckia up to half a meter high with inflorescences up to 7 cm in diameter with red-brown reed flowers and black tubular ones.

Rudbeckia amplexicaulis

grows up to 80 cm in height. Its leaves are opposite, sessile, glabrous, oval or elongated with a sharp apex and finely toothed along the edge. Reed flowers are bright yellow, tubular, located on a receptacle rising up to 3 cm, dark brown.

Rudbeckia triloba

- a lush but short-flowering plant 100-140 cm high with three-lobed lower and oval dark green stem leaves. The inflorescences are small, the reed flowers are yellow, the tubular flowers are dark brown.

Of the perennial species of rudbeckia, the most commonly grown are:

Shiny rudbeckia, or radiant rudbeckia (Rudbeckia fulgida)

- a perennial about 60 cm high with entire, narrow lanceolate leaves. Inflorescences up to 9 cm in diameter consist of orange reed and dark red tubular flowers. The variety of rudbeckia brilliantis "variabilis" has orange-yellow edge flowers and dark purple middle flowers. In addition to this variety, the varieties Goldshturm and Goldstar with golden reed flowers and a convex brown center are known in cultivation.

Rudbeckia laciniata

grows up to two meters in height. Its rhizome is horizontal, highly branched, the lower leaves are pinnately divided, and the stem leaves are tripartite. Inflorescences up to 10 cm in diameter consist of 1-3 rows of bright yellow marginal flowers and light yellow tubular ones. Of the many varieties of this species, the most common is the Golden Ball rudbeckia - double or semi-double rudbeckia with inflorescences up to 10 cm in diameter, consisting of bright yellow marginal flowers and greenish tubular ones.

Western Rudbeckia (Rudbeckia occidentalis)

- a very unusual species, similar to a tongueless chamomile. The variety of this species, Black Beauty, for example, is devoid of reed flowers, so it looks like a black cone surrounded by green bracts. Bush height 120-150 cm.

Giant Rudbeckia (Rudbeckia maxima)

- a large plant, one might say, architectural. The leaves are green with a bluish waxy coating, the reed flowers are bright yellow, and tubular flowers of dark shades grow on a strongly prominent cone-shaped receptacle. The plant is frost-resistant and drought-resistant. Inflorescences on long peduncles stand well when cut.

Rudbeckia nitida

- a two-meter bush with shiny oblong-lanceolate leaves. Inflorescences reach 12 cm in diameter. Reed flowers are yellow, tubular flowers are green. The varieties of this species, Herbstonn and Goldshirm, look impressive in the garden.

A cultivated resident of the North American steppe zones, in our flower beds it is called rudbeckia. In their homeland, yellow-brown flowers with a prominent dark-colored seed center are called “black-eyed Suzanne,” but in our country they are sun caps.

What is so attractive about perennial rudbeckia? What varieties is this plant famous for and are there flowers of other colors?

The flower belongs to the Asteraceae family, genus Rudbeckia. The stem is erect, pubescent, its height is from 50 centimeters to 2 meters.

The oval, elongated leaves can be whole or pinnately divided. The basket-shaped inflorescence reaches 15 centimeters in coverage and can have different shades of yellow-orange color. In the middle there is a black or brown convex center.

A perennial, frost-resistant plant that can grow in one place for up to 5 years, being unpretentious in care. It will decorate local areas and front gardens with its aerial plantings, and will be useful for flower beds and garden compositions. It looks more advantageous in group plantings and with low-growing surroundings of other flowers of contrasting color.

Species diversity

Four dozen varieties of rudbeckia with a long-term development cycle are currently known; hybrids are more common. There are bicolor red-brown, yellow-orange, dark orange multi- and biennials.

There are also low-growing species (30-35 centimeters), they have a variegated color and large flowers. These are bushes with a two-year development cycle.

Height 55-60 centimeters, leaves long, narrow. Both the leaves and the stem are rigidly pubescent. The inflorescence is 8-9 centimeters in diameter and has orange outer, reed petals, and dark red tubular petals in the middle. The middle of the flower basket is convex and brown. Prominent representatives of this species are the varieties Goldstar and Goldshturm.

A tall variety, more than 2 meters, grows in favorable conditions. It stays firmly in the ground thanks to its highly branched rhizome. The inflorescences, located on an erect stem, reach a diameter of 7-10 centimeters and consist of several rows of yellow petals, creating a double appearance. In the center are lighter, greenish tubular petals. The most widely known plant of this species is the famous Golden Ball.

It is an unusual flower shape - it consists of a central cone-shaped inflorescence. It does not have reed leaves, or they reach 1-2 millimeters. The middle is located on the green receptacle. The height of the plant is quite large - 100-150 centimeters. The original appearance of this variety adds piquancy to the bouquet and other compositions. It looks unusual, reminiscent of dried flowers. A new variety, Black Beauty, is known.

Tall, colorful plant. A dark, prominent center of tubular petals is surrounded by bright yellow flat flowers. The leaves are green and have a bluish tint. Representatives of this varietal variety are cold-resistant and tolerate drought well. Inflorescences are beautiful cutting material.

The bush is up to 2 meters high and has smooth, shiny narrow leaves. The color basket, 10-12 centimeters in coverage, is represented by yellow-colored flat flowers surrounded by dark green tubular petals. Noble varieties of glossy appearance Goldshirm and Herbston.

A compact half-meter plant with elongated, rounded leaves. The flowers are large, 10 centimeters in coverage. In the middle there is a tubular inflorescence, dark brownish. The outer leaves are flat, yellow-orange (three-toothed at the ends).

A breeding name that combines several varieties (glossy, dissected, hairy rudbeckia). Hybrids have solid flowers, 19 centimeters in size. Only the length of the reed petals can reach 12-14 centimeters; they are yellowish-brown in color. The middle petals are purple. Tall varieties of this species are Gloriosa Daisy and Double Daisy.

The medicinal plant Echinacea purpurea and its variety white swan are often considered among the species of rudbeckia. This is a false statement, the flowers are simply similar. They belong to the same Asteraceae family, but are classified into different genera: rudbeckia and echinacea. In addition, the first one is not considered as a medicinal plant.

How to grow

The technology for cultivating rudbeckia is simple, suitable for a novice gardener and convenient for those who do not really like caring for plants. This is why this flower has gained popularity among lovers.

Planting and propagation

This procedure is carried out by sowing seeds in open ground, seedlings and dividing the bush.

Seeds are purchased at a specialized store or collected from dry, faded baskets by shaking them onto thick cloth or paper. Well-dried planting material is planted in the ground. Plants grown from such seeds can be significantly inferior in decorative value to the mother flowers.

Sow in open ground

Seed material is sown during the summer, by direct sowing into prepared soil in a garden bed. Soil requirements: a mixture of compost, peat and sand, or it can be the soil that is available. However, more fertile and well-drained soil favors especially lush and friendly flowering.

Make small furrows, sow seeds and cover with soil. This perennial will bloom next year, and this season it will only gain green mass. The advantage of this method is that these seedlings will come to life next spring and begin to bloom earlier than those planted as seedlings.

To get flowering this year, they use the seedling method. Sowing is done in March.

The container, box or pots are filled with soil mixture;
Seeds are sown in shallow grooves and sprinkled with a thin layer of earth;
Spray with a spray bottle, moisturizing;
To create a greenhouse effect and better germination, cover the containers with film;
Shoots will appear in 10-14 days; if necessary, they are planted when two true leaves appear;
Before planting, the seedlings are hardened off by taking them to a cool room;
It is necessary to plant in open ground in May-June (when frosts have passed) after the plants reach a height of 15-20 centimeters.

Rudbeckia bushes are quite spreading; to mark the place for planting, an interval of 50 to 100 centimeters is left between the bushes, depending on the height of the plant. Some of them need garter and support.

Division of rhizomes

From spring to late summer, as well as in September, the flower can be replanted by dividing the bush. For this purpose, plants that have reached 2 years of age and above are used. The root of the plant is separated from the stems, leaving the buds. The separated parts of the root are planted in a permanent place.

This procedure is performed at least once every 2-4 years. Otherwise, the flower loses its attractiveness and degenerates.

Care and feeding

It is better to plant flowers of this species in sunny areas; in the shade it will stretch out and bloom later.
The plant needs watering only in dry times.
Weeding is done regularly, which loosens the soil.
Plants 1 meter high and above need staking, although they have rigid stems.
Faded flowers and dry leaves are removed as they appear, which has a beneficial effect on the setting of new flower stalks.
Fertilizing is done 2 or 3 times per season, with special complex fertilizers, this is useful both for flowering and for better wintering.
In order for the plant to survive the winter well and not freeze, in the fall the above-ground part is pruned to the root, leaving a rosette of basal leaves. It is advisable to mulch the planting sites with humus. You need to rake the shelter carefully in the spring, trying not to damage the rosette, which will give rise to the growth of new stems.

Protect from pests and diseases

Rudbeckia is rarely affected by flower diseases. Sometimes powdery mildew “attacks”. You can get rid of infected areas by removing branches, as well as by spraying the plant with a solution of copper sulfate.

Other pests: nematodes, leaf-eating insects are removed using special preparations, as well as folk remedies. You can use infusions of garlic, tobacco dust, and celandine. Diseased bushes are burned, and the area under them is disinfected with manganese.

Prevention of problems is timely watering, loosening and fertilizing of plantings.

By planting rudbeckia you can disguise unsightly places and abandoned corners of the garden and vegetable garden. Everyone knows the golden ball that grows in every palisade and conquers a huge area, forming a yellow, sunny blanket.

Low-growing hybrids are even planted as a border or fence. The plant looks attractive both alone and in groups.

Surrounded by other low-growing flowers, the tall rudbeckia stands out. It can be planted in the background or in the center of a mixborder.

A good combination is obtained with flowers of blue, pink, red and white. Cereal plants will also make excellent company. It is worth remembering when composing a composition that a spreading bush will grow and provide shade to its surroundings. Therefore, flowers planted nearby should not be too demanding on lighting.

If you look at the photo of rudbeckia, you might think that it is a chamomile, only bright yellow. For most novice gardeners, rudbeckia, planting and caring for which does not cause any difficulties, is a real find. And the variety of varieties and long flowering of the crop allows these bright “suns” to be widely used in landscape design.

Description of rudbeckia: varieties and varieties

Perennial rudbeckia has about 40 varieties. Almost all of them are unpretentious and take root well. Rudbeckia flowers, depending on the variety, have many shades of yellow and orange. This flower prefers sunny places on the site, but even in light shade it feels quite confident.

Common varieties of perennial rudbeckia:

Rudbeckia hybrid. It can reach a height of 70 cm. Its flowers resemble a large chamomile with a convex core. Shades vary from yellow to red-brown. Hybrid rudbeckia blooms from mid-summer to autumn.

Rudbeckia hybrid

Rudbeckia dissected. The tallest representative of the species. Reaches a height of two meters. It is also considered the most unpretentious. It is characterized by long flowering, which lasts from mid-summer until the very first frost. The inflorescences of dissected rudbeckia are bright yellow, ligulate, tubular, arranged in 3 or more rows.

Rudbeckia dissected

Rudbeckia glossy. Another tall variety of rudbeckia. Large flowers up to 12 cm in diameter will decorate your flower garden from mid-summer to early October.

Rudbeckia glossy

Rudbeckia hairy. Grows up to 1 meter in height. Double orange and golden flowers will delight you from mid-summer until the first frost.

Rudbeckia hairy

Rudbeckia brilliant. The height of the plant reaches 80 cm. It blooms throughout the second half of summer with lush inflorescences of dark purple or orange color.

Rudbeckia brillianti

Planting a plant

You can sow rudbeckia seeds directly into open ground in May, and in the northern regions in June. And although rudbeckia is undemanding to the soil and can live even on clay soils, it is best to fertilize the bed for sowing. This way your flowers will grow more readily and more luxuriantly. Having scattered the planting material onto the prepared area, sprinkle it on top with a thin layer of earth and lightly sprinkle it with water. By autumn, rudbeckia will have sprung up, and the seedlings can be planted in permanent beds. If you sowed rudbeckia in its permanent habitat right away, then you can expect flowering next year.

Rudbeckia seeds

You can also sow seeds at home or in a greenhouse for seedlings in April. And at the end of May, when the probability of return frosts is low, the seedlings can be planted in the beds.

Advice. When transplanting rudbeckia from a greenhouse or pots into the garden, make sure that the planting depth is the same as it was in the container.

Plant care

Rudbeckia is a persistent and unpretentious plant, so for its cultivation it is quite enough to comply with the simplest conditions. To care for flowers you need:

Fertilizer and feeding of rudbeckia

Rudbeckia responds well to fertilizers. It is necessary to fertilize twice a season. The first feeding is necessary for plants at the beginning of growth, when the root system has already developed a little. Complex mineral fertilizers are well suited. For example, you can dilute 1 tbsp. l. Agricola in a bucket of warm water. For each square meter it is necessary to add at least 3 liters of solution.

For better development, rudbeckia needs to be fed

After 20 days, fertilize again. For the second time, a solution of 1 tbsp is better. l. nitrophoska and 1 tbsp. l. Ross fertilizer in a bucket of water. The consumption is the same as for the first feeding.

Rudbeckia propagation

In addition to seed propagation, this flower can be propagated by division. It is recommended to divide rudbeckia bushes every five to six years. Growing in one place for a long time, this flower produces abundant growth. Large rudbeckia bushes must be dug up and carefully divided into parts. Plant the delenki in the garden, keeping a distance.

When planting, leave enough space between rudbeckia bushes.

Propagation of rubdecia, regardless of whether you are dividing a bush or replanting young shoots, is best done before the plant enters the phase of active development. Early spring or autumn is suitable for this, after the plant has completely bloomed.

Diseases and pests

Rudbeckia is practically not susceptible to diseases. It is extremely rare to encounter powdery mildew. This disease manifests itself by forming a white coating on the leaves and stems, reminiscent of flour. For control purposes, the culture is sprayed with a one percent solution of colloidal sulfur. You can treat damaged bushes with a solution of copper sulfate. For 10 liters of water you need 80 g of vitriol.

Powdery mildew

There are cases where the plant is damaged leaf nematode. It is expressed by the appearance of brown spots on the leaves, which subsequently die. Against nematodes, it is best to use special preparations that can be purchased in the store. If the treatment does not help, remove the damaged bush and burn it, and treat the area where it grew with a solution of potassium permanganate.

Advice. Rudbeckia should be regularly checked for the presence of leaf-eating insects.

In general, this flower rarely gets sick and is damaged by pests if it is cared for.

Rudbeckia perennial: combination with other plants

When planting rudbeckia in combination with other plants, you need to take into account the considerable dimensions of the bush. After all, some varieties of rudbeckia can reach two meters in height, which can create shadows and harm some light-loving plants.

Rudbeckia in a country flower bed

Rudbeckia perennial in landscape design

In landscape design, rudbeckia can be used anywhere. It will perfectly decorate a garden in a rustic style, creating ease wherever this flower is planted, be it near a fence, against the backdrop of buildings or along garden paths and sidewalks.

Yellow daisies are always appropriate in any mixborder. Tall varieties that need support are best planted in the background so that they can be discreetly covered by lower crops. In the fall, asters and chrysanthemums will look spectacular with rudbeckia. An equally original composition can be made with purple echinacea. You can add variety to your landscape design by planting rudbeckia along with cereals, which will add lightness to the composition, and rudbeckia flowers will take on the role of a bright spot.

Rudbeckia in landscape design

Growing rudbeckia in the garden is a real pleasure, because you still need to look for such unpretentious and easy-to-care flowers that easily grow in open ground. These plants are extremely good both in garden beds and when cut. And the duration of flowering will allow you to take bright photos in the garden even in the midst of autumn, when many crops have already faded.
