Coreopsis: origin, description, photo

The genus Coreopsis is included in the largest family of flowering herbaceous plants - Asteraceae. It has more than 120 species of herbaceous annuals and perennials, the bulk of which come from Central America and the South American tropics. A total of 8 species are considered indigenous to North America, some are found in the tropics of Africa, in Hawaii.

Know! Gardeners loved this luxurious exotic plant with bright flowers so much that they came up with several affectionate nicknames for it: lenok, brown-eyed, Parisian beauty, sunshine in the garden, yellow daisy.

Herbaceous perennials grow from 30 to 120 cm in height, some specimens are classified as subshrubs. To comfortably endure the winter, exotics accumulate a supply of nutrients in a powerful rhizome. Their erect stems are branched and crowned with dense opposite foliage. The plates are varied in shape - pinnately dissected, lanceolate, needle-shaped, linear, palmately divided, broadly oval. A common feature is also the inflorescences in the form of baskets with jagged edges, located on long peduncles. Like other members of the Asteraceae family, the basket consists of two types of flowers - reed and tubular.

The tubular flowers are small, numerous, yellow or brown. They form a beautiful dense core of the bud. Multi-colored petals, painted in warm colors, are nothing more than reed flowers. They are located along the edges of the bud. Color varies greatly depending on the variety.

The main colors inherent in exotics are yellow, orange, pink, and red. Bicolor petals are often colored in two shades - brown at the base and the main color. That's why exotic is called brown-eyed. The number of petals affects the terryness of the basket and depends on the varietal characteristics. Many species are characterized by repeated flowering, which occurs after a short period of time from the main one.

After wilting, small achenes, similar to insects of the bug species, appear in place of the tubular flowers. They are characterized by good germination, lasting for 3-4 years.

This is interesting! Coreopsis gets its botanical name from the shape of its seeds. Literally from Latin, the name of the flower is translated “bug-like” or “bug-like.”

One year

Unlike perennials, annual coreopsis (another name is “maiden eyes” or gypsy) belongs to the dwarf group. At the same time, it blooms 2 months longer than its “relatives”. The maximum height of the stem is 30-50 cm, and for short ones it is 15-25 cm. Of the 70 varieties of the Asteraceae family, only ten are cultivated.

If possible, the bush is pruned after flowering at a distance of 10-15 from the root collar. As a result, the stem shoots out buds again. So you can enjoy the “sunny meadow” until late autumn.

Dying – natural dye

Before planting, maiden eye seeds are soaked for a day in water, which acquires a yellow tint. This is one of the reasons why the plant received its name.

The water procedure helps to activate the growth of the branching stem. Although it is thin, it is still elastic enough to stretch up to 100 cm in height. Most of the leaves are concentrated in the basal bundle. Then they are arranged alternately. Lush inflorescences of coreopsis are presented in the form of lush baskets up to 5 cm in diameter. The petals have jagged edges and are variegated in color. It can be either fiery yellow or dark red. It all depends on the variety:

"Crimson King". Showy carmine flowers with dark brown stripes/splashes. The bush grows up to 30 cm.
"Red Tiger" or "Bengal Tiger". Red spots with jagged edges appear on the bright yellow petals. Plant height – 15-20 cm.
"Golden Severin" Large orange flowers (4 cm in diameter) adorn low-growing stems (20 cm).
"Gold Teppich" The inflorescences are amber-yellow in color. The width of umbrellas can be up to 5 cm.

When growing annual coreopsis from seeds, special attention is paid to watering. Irrigate the planting only if the soil is completely dry. With regular and heavy rainfall, this is not necessary. The crop does not tolerate excess fertilizer. A small amount of compost is applied in spring or autumn during the period of abundant flowering. Fertilizing is carried out immediately after pruning.

In order for the bush to be lush and bloom densely, it is necessary to clear it of wilted/dry leaves, as well as shoots. By loosening the soil, the roots are saturated with sufficient oxygen.

Roulette is not Russian roulette at all

A special place in the garden is given to another type of colorful annual - coreopsis "Roulette". He is elegant and magnificent, capable of surprising even an experienced florist. Its petals are painted a rich scarlet color. Their ribbed edges blend exquisitely into any garden exterior. Moreover, thin umbrellas (diameter - 7 cm) have another row of thinned petals. These narrow yellow tendrils are the highlight of the Roulette variety. To create a piece of paradise, plant next to them:

cornflowers;
asters;
echinacea;
chamomile;
gaillardia;
zinnias.

This assortment creates an original clearing, above which 50-centimeter “gypsies” rise. The peculiarity of this variety is that it grows quite quickly and is not afraid of drought and cold weather. The best way to grow coreopsis roulette is from seeds. Sowing is carried out either in late autumn for the winter (October), or in the spring, as soon as the snow melts.

The planting depth is 0.5-1 cm. The first shoots in the form of 2-3 leaves must be thinned out.

Drummonda - always in fashion

The height of the crop is 40-60 cm. Coreopsis flowers are distinguished by their large size and their yellow color with a shaggy burgundy core. It can be either wide or narrow. The ruffled, tongue-shaped petals look elegant on graceful stems. The leaves of the plant are pale green in color and resemble the feathers of a firebird. The flowering period begins in July and lasts until October.

Many gardeners will like one of the varieties of Drummond - "Early Sunrise". Terry coreopsis fascinates at first sight. Botanists associate its shaggy flower with the rising sun. Luxurious bunches consist of many petals that have embossed edges and different lengths. Such a spectacular “cloud” creates a charming atmosphere in the evening garden. In the light rays, the flowerbed shimmers with amber colors.

Types, varieties of coreopsis

Yellow chamomile is beautiful in its diversity. There are annual and perennial species of this plant, but perennials are more popular among gardeners. Let us consider the characteristics of the main perennial representatives of the genus and the most popular varieties. In culture, you can most often find 5 varieties of exotics:

coreopsis grandiflora – large-flowered;
coreopsis verticillata – whorled;
coreopsis rosea – pink;
coreopsis lanceolata – lanceolate;
coreopsis auriculata – ear-shaped.

In its native North America, the tall, stately shrub of the large-flowered variety grows in open spaces in harsh desert conditions. The desert climate is treacherous: during the day the sun mercilessly bakes, and at night the air temperature drops to almost zero degrees.

Even poor soil and an almost year-round lack of normal precipitation do not bother the exotic. For the ability to winter in the central zone without shelter, a high degree of drought resistance and decorative qualities, the unpretentious American is very fond of gardeners.

Important! This species cannot be called durable; if it is not divided once every 2-3 years, then it will not grow in one place and will gradually disappear. The plant easily tolerates frequent transplants.

The short-lived herbaceous perennial has straight, branched stems reaching a height of 0.8–1.0 m in the wild. Cultivated species are somewhat lower and more compact - the height and width of the bush is 45-60 cm. The leaf cover is divided into 2 types - in the upper part of the stem there are pinnately dissected plates, the lower leaves are whole. The decorative period begins in June and lasts until the end of summer. Large single baskets with a diameter of 5-8 cm, opening, attract pollinators. The tubular center is dark yellow, and the petals are a rich golden hue. They are great when cut and last up to 10 days.

The most popular cultivars: Baden Gold with large inflorescences and a bush 70-90 cm high; Mayfield Jant is slightly shorter; Sunburst; "Sunny Bunny"; “Early Dawn” is a compact hybrid 45 cm high, throwing out a peduncle with a single semi-double bud. The central part is painted in dark yellow tones, the edges are slightly lighter.

Remember! Most coreopsis grandiflora cultivars reproduce only vegetatively. Only the Early Dawn variety can be grown by seeds.

The whorled variety received its unusual name for the structure of thin, needle-like leaves of a light green hue, collected in whorls. The tall species reaches a height of over 1 meter and tends to occupy a large area due to the growth of rhizomes.

In the wild, it lives in light forests along the Mississippi River. Tolerant to drought, poor soils, heat. Loves plenty of sun, but feels quite normal in light partial shade. The strong, rigid stems are highly branched; on the tops there are many yellow baskets with a slightly darker middle. Depending on the variety, the diameter of the buds is 3-5 cm. The corollas open by mid-summer and delight the eye almost until the end of the season. Can grow in one place without division for up to 6 years.

The best hybrids are Moonbeam and Zagreb. Both of them are short (up to 30 cm) and have low growth rates. The Moonbeam variety has pale yellow corollas, while Zagreb has golden corollas. There is a large-flowered form of Grandiflora, which is distinguished by the abundance of baskets on the bushes.

The pink flaxen is similar in appearance to its whorled counterpart. It differs from it in its short stature of 15-30 cm and also likes to occupy a large area, growing in width up to 70-80 cm. Its flowers are small, only 2 cm in diameter with a yellow core and pink petals.

The flowering period falls in mid-summer and lasts until the end of September. Prefers moist soils with moderate levels of organic matter, because in the wild it grows along the coastline, in the swamps of North America. He doesn’t have many varieties, the best are “Sweet Dreams” up to 40 cm high with a white border along the edge of bright pink petals; "Heaven's Gate" with bushes up to 30 cm tall and abundant flowering. Pink petals acquire a purple tint towards the middle; "American Dream" 30-40 cm high with deep pink corollas.

On a note! The pink variety has a low degree of frost resistance, but gardeners highly appreciate its resistance to both drought and short-term waterlogging. It is recommended to cover it with fallen leaves for the winter.

The lanceolate lenok is native to the central region of North America, Mexico. There, medium-sized bushes 50–60 cm high are found along the sides of highways. Pointed lanceolate plates are attached to small petioles. In the upper part of the stem, their number rapidly decreases. From July to mid-September it pleases with its small drooping baskets (3-6 cm) of a golden hue. Varieties:

Goldfink. A low cultivar 30 cm tall. The corollas are rich yellow;
Sternthaler. Height up to 60 cm, diameter of bright yellow baskets with a burgundy eye about 6 cm;
Golden Queen. Height 50-60 cm, golden baskets 6 cm in diameter;
Little Sandial. A low-growing variety with a height of 30 cm. In the center of the yellow buds there is a red-brown eye;
Rotkelchen. It has bright yellow flowers with a red center. Diameter 4-5 cm;
Creme Brulle. The height of the cultivar reaches half a meter, the baskets are light yellow.

The auricular coreopsis is native to the southeastern United States. This perennial has a short height of 10-30 cm. Elongated oval leaves 1-6 cm long are located only in the lower part of the stems. There are serrations along the edges of the bright yellow corollas; the corolla is 4-6 cm long. After pruning, repeated flowering is possible. It reproduces vegetatively and by seeds and attracts pollinators to the garden.

Of the best hybrids noted: Nana and Zamfir. Nana has dwarf dense bushes that are prone to spreading. The buds are bright orange-yellow, the disc is yellow. Flowering is abundant from late spring to early autumn. Zamfir forms low growth with rounded leaves and orange heads. Ideal for borders and container planting.

This is interesting! In the Zamfir variety, young flowers have a grooved surface of the petals. As you age, it smoothes out.

Coreopsis auricularis

Coreopsis auriculata grows in the southeastern United States.
The plant is low-growing, usually up to 30 cm tall. Simple, medium-sized leaves form a rosette and cover half the stem. The yellow small flowers look like daisies. Timely pruning of inflorescences prolongs the flowering of the bush. Coreopsis auricularis. Variety 'Zamphir' Interesting varieties:

'Nana'. A very small dense bush of oval leaves. In spring and early summer it is covered with orange-yellowish flowers. It can bloom again (but not so abundantly) in summer and autumn.
'Zamphir'. Also a small plant with rounded leaves, orange-golden flowers located on straight shoots.

Coreopsis perennial planting

Planting a Parisian beauty on your site is very simple. This can be done in several ways - seedlings, sowing seeds in a flower bed and sowing before winter. You will learn about the cultivation of seedlings in the corresponding section of the article, but for now let’s talk about what conditions the exotic will require for development and lush flowering.

When to plant yellow daisies

The timing of perennial planting depends on several factors. Firstly, zoning is taken into account, and secondly, the available planting material.

If you are going to plant yellow daisies with seeds, then this can be done in spring or autumn. When planting in autumn, choose the time so that the seedlings do not have time to appear, i.e. there should already be stable frosty weather outside. Even a slight thaw will provoke the growth of the embryo and the tender seedlings will die.

The timing of spring planting varies in different regions. Thus, in Siberia, the Urals and the central zone, the plant is grown through seedlings, which makes it possible to obtain flowering specimens by the beginning of summer. Seeds are sown in open ground so that they are not damaged by frost. For insurance, you can cover the seedlings with lutrasil or agrofibre. In the south of Russia you can sow in mid-April, in the Moscow region in early May or later, but then the flax will bloom only in the next season.

Important! Remember that planting in open ground is carried out only after the return frosts have subsided. To protect the seedlings of the heat-loving American from sudden weather changes, organize a temporary shelter.

Selecting a location

To plant exotic plants on their site, gardeners often resort to a little trick. The plant is provided with conditions that are as close as possible to the natural habitat of the species in the wild.

Having studied the description of the varieties of the American guest, we can conclude that he will need an open, sunny place where a lot of snow falls in winter. The whorled and pink variety of yellow chamomile can tolerate light shading, while other species in the shade will begin to wither and lose their decorative effect. The delicate stems do not like drafts or cold winds, so the best location for the bushes would be a place close to a fence or building. Select the site in such a way that the perennial will grow on it for at least 3-4 years.

The soil

In the wild, lenok lives on poor soils, but this does not mean that in the difficult climate of another country it will feel good on the same type of substrate. An important condition that exotic plants will require from the gardener is loose, well-drained soil with a moderate degree of moisture and fertility.

Important! Pink coreopsis is suitable for soil of average fertility. On soil rich in organic matter, it will lose its decorative properties, begin to produce many shoots, but will not bloom.

To create suitable exotic conditions, add sand to too dense soil, organic matter or mineral fertilizers to poor substrates. The soil can be compacted using chernozem or humus, and at the same time its fertility will increase.

Landing technology

Before planting the Parisian beauty, prepare the area. It is better to dig it up in advance, adding the necessary components to improve the structure and fertility of the land. Prepare small planting holes at a distance of 30-40 cm from each other for low-growing cultivars and 50-60 cm for tall ones. In each hole, organize drainage from crushed stone or broken brick, since the American guest does not tolerate excess moisture in the root system area. After planting, be sure to water the area and mulch it with compost. Provide support for seedlings of tall hybrids.

If you decide to decorate your balcony with low-growing species, choose fertile soil of medium density. Be sure to place a drainage layer on the bottom of the container. The distance between specimens is 20-30 cm.

Coreopsis pink

Coreopsis rosea is a low plant (about 40 cm), forms a dense bush up to 50-75 cm in diameter. Numerous shoots are covered with narrow linear leaves. Flowers up to 2 cm in diameter are pink with a yellow center. Flowering lasts from June to September. Coreopsis pink. Variety 'Sweet Dreams'. Photo from footprintsplants.com Varieties of pink coreopsis:

'Sweet Dreams'. The inflorescence is formed by crimson petals, turning into a white border along the edge, the center is yellow.
'Heaven's Gate'. Height from 20 to 40 cm with pink-purple petals.

Caring for perennial coreopsis

The American guest will require a minimum of attention from the gardener, because it is drought-resistant and can grow without fertilizing. But to improve its decorative properties, it is recommended to take the following measures:

observe the irrigation regime;
carry out timely pruning and removal of faded inflorescences;
apply organic and mineral fertilizers according to schedule;
mulch, loosen the soil, remove weeds;
organize support for tall cultivars;
if necessary, take care of winter shelter.

Remember! Mulch saves the gardener from frequent watering, prevents the formation of crust on the ground, and inhibits the growth of weeds.

Watering, pruning

High drought resistance is granted to the Parisian beauty by nature. Therefore, irrigation should be rare, only when necessary. So, if the summer turns out to be rainy, then watering the exotic plant will not be required. If the hot, dry weather lasts for a long time, water the flower moderately after the top layer of soil has completely dried. When growing yellow daisies as a potted crop, water them only after the soil has completely dried.

After the first wave of flowering is complete, remove a quarter of the stems. This measure stimulates the growth of additional flower stalks and soon you can expect the appearance of new baskets. To make the bushes look neat, remove faded inflorescences in a timely manner; new ones will not keep you waiting.

Top dressing

In order for the American guest to show himself in all his glory, additional feeding will be required. Fertilizers are applied twice per season. During the budding period or a little earlier, treat the seedlings with organic fertilizer. Diluted compost is best suited for these purposes. After the first wave of abundant flowering, apply the full mineral complex in accordance with the instructions for use. If the soil on the site is too poor in minerals, fertilizing with a low concentration of potassium-phosphorus complex is allowed in the fall.

Remember! Autumn fertilizing should not contain nitrogen, which provokes shoot growth.

Loosening and supporting the plant

To improve root respiration, the space around the bush must be loosened. This is done after watering or the day after precipitation. After loosening, the ground around the bush is mulched with humus.

Large specimens of the genus Coreopsis require support, especially if they are planted alone. With crowded planting, the bushes are able to support each other, but the crowding has a bad effect on the microclimate and can lead to the development of putrefactive processes. Before active growth begins, install support. You can make it yourself using a metal-plastic pipe and elastic wire. Bend the pipe section to form a circle or rectangle and secure the ends.

Drill 4 holes around the perimeter and insert metal rods inside. Carefully install the support around the bush by inserting lengths of wire into the ground to the desired level. Such a support will be more durable than a wooden one.

Preparing the plant for winter

In central Russia, yellow daisies winter well without any shelter. If the area around the plantings is strongly blown by the wind, hill up the root collar and sprinkle with a layer of leaves. Before this, you need to remove the entire above-ground part of the bush, leaving 10 cm of stems.

In Siberia and the Urals, it is recommended to approach the organization of winter shelter more responsibly, because a heat-loving guest may not survive too low temperatures. After autumn pruning, mulch the root collar high with humus, throw a layer of spruce branches on top and cover with spunbond. Under a blanket, the plant will comfortably endure the winter cold.

Advice! The less snow falls in winter, the higher the likelihood of rhizomes freezing at extremely low temperatures. Try to create a snowdrift at least half a meter high above the shelter.

Botanical description of coreopsis

Coreopsis is a perennial or annual rhizomatous plant. Stems are thin, highly branched, 0.4-0.9 m.

The green leaves are maple-shaped or dissected to the main vein, lanceolate or narrowed. They grow on the lower half of the stems, arranged crosswise.

Yellow, brownish-red, pinkish and crimson flowers with a dark spot in the center begin to form in June. There are simple and terry ones. They have 8 linear, narrowed petals with jagged ends. The end of flowering occurs only with the first cold weather.

In place of the flowers, flat seed pods appear. They contain up to 5 hundred seed material. From the Greek coreopsis is translated as bug-like. This is due specifically to the fruits, which are similar to these insects.

Reproduction of coreopsis

Parisian beauty reproduces by seeds and vegetatively. It should be noted that you should not collect seeds from your wards if the package was marked F1. This type of seed is called a first generation hybrid. Its seeds are either sterile or do not inherit varietal characteristics. For propagation of hybrids (especially large-flowered varieties), vegetative methods are preferred - cuttings and dividing the bush.

Dividing the bush

Yellow daisy bushes need to be divided regularly. This is especially true for the large-flowered species. Which requires a transplant every 2-3 years. The remaining varieties are subjected to vegetative propagation as they grow. The best age for division is 4 years.

A few instructions for dividing will help you correctly propagate perennials on your site:

The best time for the event is spring, when the soil and air have already warmed up (May). Autumn replanting can be carried out in the south of Russia in early September, so that the plant has time to take root before the onset of cold weather.
Water the bush generously and carefully remove the rhizome from the ground, trying to cause minimal damage to the lateral roots.
Clean the rhizome from the soil and cut it into several pieces with a sharp knife. Each division should have 2-3 dormant buds for resumption of growth and a developed root lobe.
The cuttings need to be planted in a hole with slurry. To do this, the area is first fertilized, dug up, and water is poured into the holes to form a slurry.
Plant cuttings, compact the soil, and mulch with humus.
The transplanted specimen is already an adult plant, so it will bloom in the same season.

Know! If you need to replant a perennial, you can safely carry out your plans. The plant takes root very easily in a new place, just replant it together with a lump of earth.

By cuttings

When propagated by cuttings, the first flowering will occur only in the next season. In mid-summer, take cuttings from the most developed shoots. Make a cut 10 cm below the internode and remove the lower leaves. You can root the cuttings in a loose, fertile substrate. A mixture of humus, sand and garden soil in equal proportions is perfect for these purposes. Fill the container with substrate and plant the cuttings in it, first soak them in a heteroauxin solution for 5-6 hours.

Place boxes with layering in partial shade; you can place them under bushes. Until complete rooting, irrigate the seedlings frequently, then switch the watering to moderate mode. For the winter, cover the box with a layer of fallen leaves, cover it with spruce branches and cover it with lutrasil. Next spring you can plant the young shoots in a permanent place and wait for the first buds to appear.

What does coreopsis look like?

Coreopsis is a herbaceous plant or subshrub of the Asteraceae family. It has straight branched stems and pinnately dissected or palmately divided leaves located oppositely. It rises up to 45-120 cm above the ground, depending on the species. It blooms in baskets consisting of brown or yellow tubular flowers and marginal reeds of pink or golden hue. The fruits are achenes containing up to five hundred small grains.

Coreopsis flowering time

Usually, with proper care, the crop blooms in mid-summer in July and August. The timing of decoration depends on the planting method. If you sow the perennial directly into the ground, the buds will still open, but later - at the end of summer or early September.

Coreopsis from seeds

Most exotic species reproduce well by seeds. For regions with harsh climates, the seedling method of planting the luxurious American plant is suitable. You will learn the nuances of growing seedlings from this section of the article.

Selection and preparation of seeds for sowing

When choosing seeds, you need to take into account zoning, the possibility of placement on the site, and the desired result. If you want to fill a ridge or decorate a border, choose low-growing cultivars. Tall varieties are suitable for creating a solo composition or the central part of a mixborder.

Carefully study the information on the seed package. Remember that when purchasing hybrid seed, adult bushes are propagated only by vegetative methods. The planting diagram drawn on the packaging will help you in the future to correctly plant the perennial in the flowerbed. Pay attention to the manufacturer, try to choose seeds from large agricultural companies. Such suppliers take care of the health of the seed and carry out preventive disinfection. Large producers do not allow re-grading, so you are guaranteed to purchase the necessary cultivar.

Important! Pay attention to the expiration date of the seeds. For successful cultivation, it is better to have at least 1-1.5 years before the expiration date.

If you bought seeds, processing is not necessary. For those collected from your own garden, such a measure is necessary. You can protect seedlings from diseases by treating them for half an hour in a solution of potassium permanganate or any fungicide. After processing, rinse the material thoroughly and soak for 6-8 hours in a growth stimulator. Phytohormones activate the embryo, awaken the seed, and facilitate the germination process.

Containers, soil

For sowing, use a regular seedling box or mini-greenhouse. Inside the greenhouse, the seedlings will be provided with the necessary microclimate. Be sure to make holes to drain excess water after watering and root respiration.

The substrate for sowing must be loose and fertile. Mix 2 parts of humus with the same amount of garden soil, add half a portion of sifted sand. This soil mixture will allow you to grow healthy seedlings. Remember that garden soil may contain pest larvae, weed seeds, and fungal spores.

Attention! In order not to lose the seedlings, be sure to heat treat the soil (steaming, calcining) or water the soil with potassium permanganate and Fitosporin.

Sowing seeds

Sowing of seeds is carried out at the end of March according to the following algorithm:

fill the container with a 1-2 cm layer of drainage - crushed stone, sand, expanded clay;
fill the container with the treated soil mixture, compact it, water it generously;
sow the seeds evenly, planting them to a depth of 0.5 cm;
organize a transparent shelter - film, glass;
Place the box on a warm, lit windowsill.

Seedling care

At a temperature of 20-22⁰C, seedlings will appear in 2-3 weeks. They will require standard care for flower seedlings. After germination, remove the cover and slightly reduce the temperature. Provide uniform, intense lighting and keep the soil in the box moist. A slight decrease in temperature will protect the seedlings from stretching. If necessary, install additional lighting. When using a fertile substrate, fertilizing can be applied once, after picking. A complete mineral complex will help seedlings quickly adapt to new conditions and increase green mass.

Picking seedlings

I pick seedlings at the stage of 2-3 true leaves. Transplantation is carried out in separate containers using the same soil mixture that was prepared during sowing. Water the boxes with seedlings generously, remove the seedlings one at a time and place them in a larger container. Add the required amount of substrate, compact, and water.

When and how to plant seedlings in open ground

Planting seedlings in open ground can be done strictly after the last spring frosts have subsided. By this moment, most of the specimens will have gained color and grown powerful shoots.

Advice! 2-3 weeks before transplanting, harden the seedlings, leaving them in natural conditions for the whole day. This needs to be done gradually.

In Siberia, planting begins no earlier than the first ten days of June, in the middle zone by mid-May, and southerners can plant seedlings as early as the end of April. If the weather suddenly changes its character, first cover the tender seedlings with lutrasil. Transplantation is carried out into the wells in the manner described above. Follow the recommended distance between bushes indicated on the seed package. For tall hybrids 50-60 cm, for short ones 20-30 cm.

Diseases and pests

Although the varietal characteristics indicate high resistance to pests and diseases, no one gives a complete guarantee. And we have to face such problems.

Fungal diseases

Such ailments include leaf rust and fusarium. To combat, diseased leaves that are covered with reddish spots are torn off and the entire bush is treated with fungicides. If the shoots are twisted, the buds dry out and crumble, there is a virus. In this case, coreopsis is removed completely to prevent the spread of infection to neighbors.

Insects

The most frequent guests on the bushes are aphids, caterpillars and beetles that eat soft, juicy greens. For control, chemical agents are used for aphids and other insects. Large specimens are collected by hand.

Planting perennial coreopsis in open ground with seeds

Seeds can be sown in open ground in such a way that by the time the seedlings emerge, the frosts have already passed. Mid-May for Siberia and the Urals, mid-April for the South of Russia and early May for the Middle Zone. Sow prepared seeds into moistened holes without deepening them. Sprinkle with a thin layer of soil. To speed up germination, throw a film over the hole. In 2 weeks, friendly shoots will appear. They are thinned out at the stage of development of the third leaf, leaving only strong specimens. Further care is the same as for adult plants.

In the South, you can sow seeds before winter, in early November. Planting conditions are similar to those described above. With the arrival of spring, sprouts will hatch, which are then thinned out and cared for as usual.

Flower bed design

Coreopsis is used and loved for its long-lasting blooms. It is placed in flowerbeds of perennials of continuous flowering, varying in color shades. For example, red flowers can be placed with yellow sunflowers towering in the background, blue delphiniums or next to a riot of colors of lupines.

The yellow eyes of coreopsis go well with daylilies and tall lilies. Some gardeners plant coreopsis in a bed of coniferous shrubs, using stones and ground cover plants.

Coreopsis fits into any group planting in the garden. Various combinations are used here, it all depends on your imagination.

Pests and diseases of coreopsis

The strong immunity of the exotic in alien climatic conditions made it vulnerable to fungal diseases - fusarium and rust. With fusarium blight, the fungus attacks the leaves, causing them to quickly yellow and die. Rust is characterized by the appearance of reddish-brown spots containing fungal spores. Gradually, the spots grow, interfere with normal photosynthesis, and the leaves die. If there are signs of disease, remove the affected parts and treat the bush with Fitosporin.

Attention! Much worse for the Parisian beauty is infection by plant viruses. In case of stunted growth, deformation of the baskets, or “curly” bushes, immediately remove the diseased individuals and burn them.

Of the pests, the American is only interesting to aphids, beetles and caterpillars. Aphids can be washed off with a soap solution or marigold decoction. If the treatment does not bring results, use insecticides - Karate, Intavir, Iskra. It is recommended to collect beetles and caterpillars by hand and destroy them.

Reproduction by division

Approximately once every five years, a perennial coreopsis bush must be divided and replanted .
to do this in spring or early autumn. Although the plant is so resistant that it can be divided even summer at the time of flowering.

Coreopsis perennial in landscape design

The bright buds of this exotic perennial will give a good mood to everyone who decides to plant it in the flowerbed. Landscape designers use tall hybrids to create the background of a mixborder, large flower bed, or alpine slide. They are relevant both in single and group plantings, for decoration in front of the entrance to the site.

The best neighbors for tall cultivars will be irises, sage, delphiniums, and chamomile-like relatives from the Asteraceae family - zinnia, echinacea, and rudbeckia. When cut, yellow-orange elegant bouquets will last 7-10 days.

Low-growing varieties are ideal for filling ridges, planting in rock gardens, finishing paths and borders. They are grown in small boxes to decorate balconies.

A cheerful guest from America, coreopsis, will grow in a flowerbed even for novice gardeners, because planting and caring for it are simple.

Coreopsis in the garden

Perennial coreopsis are long-flowering plants, so they can occupy a significant place in the garden.
Tall species and varieties will serve as the background in a mixborder; they will look especially beautiful with flowers that have blue and light blue pyramidal inflorescences: aconites, speedwells. The bright yellow flowers of coreopsis are beautiful on the green background of the lawn and near bush groups. Coreopsis in the foreground. Photo from pukeraunursery.co.nz Low-growing forms are perfect for the foreground of a flower garden; they make wonderful borders. They will also decorate an alpine hill or rock garden. Also, low coreopsis are good in vases and containers with blue lobelia and silver cineraria. Do Coreopsis grow in your garden? What types or varieties do you prefer?

Fertilizing and feeding coreopsis

It is best to fertilize coreopsis with organic fertilizers. Compost is ideal. It must be applied in the spring, as well as in the summer during flowering, which will make it more lush and lasting.

After fertilizing with organic matter, coreopsis blooms more actively

If compost is not available, you can use complex fertilizer.

Possible problems in growing

Under unfavorable weather conditions, the plant can become a victim of fungal infections, as well as invasion of insect pests.

Problems with leaves

The following alarming symptoms can be found on the bushes:

dry dark spots on the lower foliage - indicate septoria coreopsidis;
whitish stains are a sign of powdery mildew (Erysiphae cichoracearum);
white spots on the underside of leaves - downy mildew (Plasmopara halstedii).

If such lesions are detected, spraying with an antifungal drug, for example, Fundazol, should be carried out.

Pests

Most often, the flower is affected by aphids and leaf flies. They are easy to spot on coreopsis; just look closely at the bush. Spraying with a weak soap solution or an appropriate insecticide helps against them.

For reference! For aphids, you can use Fitoverm, Aktar, Iskra-M and other drugs containing permethrin or aversectin.

Diseases

A common disease that affects coreopsis is rust. Its traces are easy to notice on the leaves, which become covered with red spots and then dry out. For prevention, before the buds open, the planting is sprayed with a 1% solution of Bordeaux mixture or another copper-containing preparation.

Signs of improper care

A typical mistake made by those who have not previously grown this plant is excessive feeding. Because of this, foliage grows quickly and abundantly, and flowers are reduced in number and reduced in size.

Note! With excessive flooding, the foliage begins to wither, starting from the tips, and turn yellow.

Caring for coreopsis is not at all difficult; many people believe that it is enough to just plant it, and then it will grow on its own. This is partly true, but still, truly large and beautiful flowers are obtained with regular feeding.

Coreopsis whorled - botanical information

Coreopsis verticillata is a perennial rhizomatous plant that usually grows in dense branched bushes from 20 to 50 centimeters in height.
Most often it has yellow, non-double, daisy-like flowers (3-4 centimeters in diameter) with long reed petals. They have pointed or slightly rounded edges, and the center of the inflorescence is yellow-brown. In addition to yellow, the color of the side flowers (petals) can also be orange-red, cream, burgundy and two-tone. The flowers are usually solitary or collected in loose clusters. Flowering is abundant and long-lasting, beginning in late spring and continuing until the end of summer. Trimming plants in the middle of the season will promote more abundant re-blooming, however, faded flower heads are quite decorative and do not spoil the appearance of the flower garden.

The leaves of this coreopsis are similar to dill leaves and give the plant a fine texture and airy appearance.

The genus name comes from the Greek words "koris" meaning "beetle" and "opsis" meaning "like". This name refers to the seed heads of the plant, which vaguely resemble a beetle or mite. The specific name whorled refers to the leaves collected in whorls on thin stems. The genus is native to North America.

Description and characteristics

Coreopsis whorled is a herbaceous perennial of the Asteraceae family. These are unpretentious and frost-resistant plants that can often be found along highways. The bush is 50-90 cm high and up to 60 cm in diameter. The stems are rigid, branched, and erect. They have densely arranged needle-like light green and dark green leaves in opposite order. The near-stem foliage is palmate or pinnately divided, the basal leaves are entire.

Flowers with a diameter of about 3 cm, rich yellow, pink, purple, red. They resemble little stars or daisies. Towards the middle the color darkens. Flowering is abundant and lasts from the 2nd half of June until September. In place of faded inflorescences, seed pods are formed. The seeds are small and round in shape.

Important! In one place, whorled coreopsis grows for up to 5 years, after which it requires replanting.

Kinds

There are about 100 species of coreopsis, which differ from each other:

To size;
By the color of the inflorescences.

Stems are erect, branched. Plant height ranges from 20 cm to 1 m. The leaves are arranged oppositely, pinnately dissected. The inflorescences are presented as baskets on long peduncles. The marginal flowers are ligulate, yellow, brown-yellow or pink; tubular flowers are small, yellow or brown. The fruit is an achene, similar to a bug, which determines the name of the genus from the Greek word koris - bug. Russian name: Lenok or Parisian Beauty.

Coreopsis whorled Zagreb

The height of the Zagreb variety reaches only 30 cm. This low-growing plant with golden flowers loves light, but can develop well in slight shade. It is characterized by resistance to frost and can withstand winter without additional shelter.

It is not too picky about the soil, but will respond to fertilizing with an abundance of flowers. It is important to maintain a balance in fertilizing and watering. If the groundwater is high, the roots may rot. You should also not over-hydrate the plant in winter.

Important! The soil should be moderately fertilized, fresh, and slightly moist.

In 2001, the Coreopsis whorled variety Zagreb received the AGM Award from the Royal Horticultural Society of Great Britain

Coreopsis whorled Moonbeam

Coreopsis whorled Moonbeam is a low-growing variety, reaching a height of 30 cm. The flowers are pale milky yellow, 3-5 cm in diameter. The petals are long, slightly elongated, and regular in shape. The core is a darker yellow color. The leaves are needle-shaped, dark green. Frost resistance zone – 3.

Moonbeam became especially popular in 1992 after it was named Perennial of the Year by the Perennial Plant Association.

Delicate light yellow flowers make the bush openwork. The Moonbeam variety is perfect for planting in tandem with heliopsis, delphinium, salvia, and eryngium.

Coreopsis whorled Ruby Red

Ruby Red is distinguished by its rich red color. The height of the bush is about 50 cm. The leaves are needle-like, very narrow, light green. The flowers are about 5 cm in diameter, the leaves have a “ragged” effect at the ends. In the photo above you can see that the Ruby Red whorled coreopsis bush is very dense, with a uniform red-green structure.

The winter hardiness zone of the Ruby Red variety is 5, the plant easily tolerates the cold of central Russia

Coreopsis whorled Grandiflora

The Grandiflora variety is distinguished by its tall shoots, reaching 70 cm. They bear bright yellow flowers with a red splash at the base. The diameter of the bud is about 6 cm. The petals have a serrated edge. The leaves are not as tall as the shoots; they are half as tall. This makes the bush not as dense as other varieties, but no less beautiful.

In 2003, the Coreopsis whorled variety Grandiflora was also awarded the AGM Award of the Royal Horticultural Society of Great Britain

Care

Distinctive features of Coreopsis Whorled:

Frost-resistant;
photophilous,
Drought resistant.

This plant is created for lazy people, like the foxglove grandiflora.

For planting, it is better to choose open sunny places with light, moderately fertile, loose soil.

An important point is the presence of high-quality drainage . The distance between plants when planting should be at least 20-30 cm. Coreopsis Whorled is not afraid of drought, but prefers moderately moist places and does not tolerate stagnant waterlogging. After the coreopsis has bloomed, it must be cut back to one quarter of its height and fed. After some time, flowering will resume. Before the onset of winter, faded stems are cut back to the ground. In central Russia it winters without shelter.
