The cosmos plant is an annual or perennial representative of the Asteraceae family. It includes more than 20-40 different species, but only three of them are grown in the middle latitudes.

The name of the cosmos was derived from the Greek word for "decoration", such flowers are also called the cosmos or - according to the country of origin - the Mexican aster. Most of the cosmos actually live in Mexico.

The beautiful and undemanding kosmeya flower has become widespread as a garden plant, as well as a crop for cutting. Of the three types of cosmos common in horticulture, one is perennial, and two are annual.

Description of cosmos

Cosmos form bushes from half a meter to 1.5 meters high. They have thin and flexible straight shoots that can branch. Double-dissected leaf blades are located oppositely on the stems, from a distance they seem to be openwork. During the flowering period, inflorescences in the form of baskets, resembling chamomile, appear on the tops of the stems. The maximum size of such inflorescences reaches 12 cm. They can be located singly or form loose complex inflorescences. Each basket consists of light yellow median tubular flowers and large ligulate flowers of various colors (white, yellow, pink, red or purple). Relatively recently, breeders managed to get terry varieties of cosme, whose flowers resemble small peonies.

Baskets can form on bushes until late autumn. After flowering, fruits are formed in their place - acicular achenes of gray, yellowish or brown color. Their germination capacity lasts about 2-4 years.

Kosmeya is a small miracle. Cosmea ist ein kleines Wunder.

Growing cosmos from seeds

Kosmeya is easily and quickly propagated by seeds, they can be sown in open ground or grown through seedlings.

Sowing seeds

Sowing kosmeya directly on the beds should be in the spring, as soon as the snow melts from the site. Seeds are distributed over the holes, dropping 3-4 pieces into each. A distance of about 35 cm is maintained between the holes. Thin seeds should not be buried too deeply, it is enough just to lightly press them to the ground, without sprinkling them with soil. The cosmos obtained in this way will bloom in the second half of summer. Another method of sowing is podzimny. In this case, seeds are placed on the beds before the onset of cold weather in late autumn.

If the kosmeya is already growing on the site, it can give self-seeding. To control the number of plants in the spring, they only need to thin out.

Growing seedlings


Although kosmeya develops quickly enough with direct sowing in the garden to get flowering plants at an earlier date, flowers can be sown for seedlings. The seedling method is recommended for growing late-flowering, rare and large-flowered hybrid varieties. Sowing is carried out in March-April. For it, use ordinary seedling boxes or containers, as well as universal soil or any suitable soil: moderately loose, light and nutritious.

Cosmos seeds react to light, so they are spread over the surface of the soil, lightly pressing against the soil. After that, the seedlings are moistened, covered with foil or glass and placed in a bright place. At a temperature of about 18-20 degrees, seedlings should appear within 1-2 weeks. In the warmth, the seeds appear less amicably. With the appearance of sprouts, the shelter should be removed. If the kosmeya was sown too densely, the plants are thinned out or dived so that the distance between the seedlings is about 10 cm. For convenience, you can immediately place the plants in separate cups. After picking, the seedlings are kept in a moderately warm (about 16-18 degrees) corner. Such plants should bloom in June-July.

If the seedlings of the cosmos begin to stretch, they can be pinched, but this procedure will slightly postpone the beginning of flowering. To avoid this, you can use additional lighting. Before planting in the ground, it is recommended to gradually harden the seedlings, transferring them to the air on warm days.

Planting cosmos in open ground

The best time to plant

Cosmos seedlings are planted in open ground in May-June, when severe frosts are likely to pass. In this case, the height of the bushes should be at least 6 cm. For flowers, choose a sunny place, reliably protected from the wind. In shade, the bushes will not be able to grow fully. Cosmos grow best on moderately fertile, slightly acidic soil that has a good drainage layer. In too nutritious soil, the bushes will begin to actively form foliage, but not flowers. If the soil is too heavy or dense, sand or compost should be added to it.

Landing rules

Before planting the cosmos, a suitable bed is prepared for them. It is dug up or loosened and weeds are removed. After that, small holes are dug in the garden bed, keeping a distance of about 30-35 cm between them, depending on the size of the bushes, and then they are spilled with water. When the seedlings are transplanted, they are watered again.

Tall varieties of cosmeas may need support, therefore, even during planting, a stick or rail is installed next to each bush. The thin stems of the bushes are quite stable, but sometimes they can break or lie down due to strong winds.

To increase the number of baskets, especially tall bushes are pinched after they reach half a meter in height. This will promote the development of side shoots and make the plants more lush.

Cosmeia care


Caring for cosmos in the garden is not a big deal. These plants are considered drought-resistant, but at the beginning of development they need to maintain soil moisture. Regular watering will be especially necessary for the bushes before flowering. They are held not too often - once a week. To ensure that the plants have enough water, about 4-5 liters are poured under each bush. Then it is recommended to loosen the root area, and also to clear the weeds. Weeds can harm young, fragile bushes most of all. After opening the buds, it will be necessary to water the cosmos only during periods of especially prolonged heat or drought. This will help prolong flowering.

Top dressing

Cosmos growing on fertile soil may not need feeding at all. Flowers growing on poor soil are fed about three times per season using mineral formulations for flowering plants. The first feeding is carried out before the beginning of bud formation (as an option - at the seedling stage), then during budding, and the last one after the beginning of flowering. For more lush flowering, you can use foliar dressing with such preparations as "Bud", but cosmeies do not need too much fertilizer, because of it, they can fade at an earlier date. In addition, the abundance of nitrogen supplements can adversely affect flowering, stimulating foliage formation.


It is possible to prolong the flowering of cosmos without resorting to nutritional compositions. To do this, it is advised to remove dried baskets from the bushes. If the plants have grown too much, they can be trimmed a little. Such a pruning procedure will return the plantings to a neat look, and also not too much harm to flowering.

Kosmeya after flowering

Seed collection

Perennial species of cosmos can also propagate by tubers or cuttings, but annual species are most often propagated using seeds. To get the highest quality seed, several of the largest baskets are selected on the bush. To prevent the seeds from spilling to the ground after ripening, you can put gauze bags on them. Mature seeds will be dark in color. Usually, the collection is carried out in early autumn. But the cosmees obtained in this way do not always retain the characteristics of the original variety: these plants are easily re-pollinated, so only purchased seeds will surely help to get the desired result.

Even after a one-time planting, cosmos can multiply by self-seeding, while the decorative qualities of the bushes obtained in this way do not deteriorate.

Wintering of perennial cosmos

Annual cosmos are simply removed from the beds in late autumn, but perennial plants are able to overwinter under the snow. After flowering, they are cut to a height of 15 cm. Bushes should overwinter under cover, it can be formed from spruce branches. Fallen foliage is not recommended to be used - it often becomes a refuge for harmful insects. To protect the roots of the planting, you can mulch with straw, peat or bark. With the arrival of spring heat, the shelter is removed in order to avoid damping off the plantings.

If perennial kosmeya grows in a region with especially harsh and long winters, for the winter the bushes can be transplanted into pots and transferred to a warm place. In the spring they are returned back - the flower tolerates the transplant well.

Pests and diseases

Cosmos are highly resistant to pests and diseases, therefore they practically do not give the gardener such trouble. But weak, immature bushes can be damaged by snails or slugs. If gastropods were found on the plants, they are collected by hand. You can get rid of a large number of slugs with the help of traps (bowls of beer) or protect the flowers from them by creating a barrier from dumping with pieces of shell.

Sometimes in a particularly rainy autumn, cosmos can be affected by rot, but young plants usually do not have such problems.

Types and varieties of cosmos with photos and names

Although only three types of cosmos are usually grown in culture, thanks to the work of breeders, this flower has many hybrid forms and ornamental varieties.

Cosmos bipinnatus

One of the most common types. Cosmos bipinnatus is an annual plant native to Mexico. Its bushes form branched straight shoots from 80 cm to 1.5 m high. The foliage is dissected into many lobes and resembles the leaf blades of dill. The size of the inflorescences reaches 7-10 cm, the baskets can form shields or be located singly. The ligulate flowers are white, pink, red or purple in color. The tubular median flowers form a small yellow circle in the center of the basket.

This type of cosmos reproduces easily by self-seeding. It is notable for its abundant flowering, and has been used in culture since the end of the 18th century. Among the most famous varieties:

  • Dazzler - as the baskets bloom, the color of their "petals" changes from bright red to crimson.
  • Purity - a plant with flexible stems and snow-white baskets.
  • Sonata - a series of undersized cosmes, including the Sonata Pink Blush variety. It forms pink flowers with a brighter rim near the center of the basket.

Sulfur-yellow kosmeya (Cosmos sulphureus)

Annual Hispanic species. Cosmos sulphureus is considered to be more thermophilic. It forms straight, branched stems with slight pubescence. Their height can reach up to 1.5 m. The foliage of the species is dissected into feathery lobes, which are sharpened towards the apex. The shape of the baskets is a bit like the flowers of a swimsuit, and their size is about 5-8 cm. Their reed flowers are colored orange or golden yellow. Tubular flowers are also colored yellow, and their anthers have a dark orange tint. Famous varieties include:

  • Bilbo - forms semi-double orange inflorescences.
  • Diablo - forms red-orange inflorescences.
  • Lemon Cross - half-meter bushes with lemon-colored baskets.

Blood-red cosmos (Cosmos atrosanguineus)

Mexican perennial. Cosmos atrosanguineus is also known as "black kosmeya" due to the very intense coloration of the baskets. This species is considered very thermophilic, therefore it is grown less often than others. To preserve such a cosmos until the next season, in the fall you will have to transplant its bushes into pots, and transfer them to the house for the winter. Flowers can sometimes hibernate under good cover.

The species is distinguished by complex foliage with an unpaired number of leaf blades. Flowers can have a variety of colors, including very dark tones. The marginal flowers have a velvety surface and a chocolate-like aroma. There are also terry varieties. Among the most common:

  • Antiquity - short plants form baskets with a changing color. At first they have a wine tint, which changes to a bronze-pinkish.
  • Brightness - a profusely flowering variety with bright double inflorescences.
  • Double click rose bon-bon - forms terry pink baskets that retain their appearance for a long time after cutting.

Kosmeya is perennial. Planting and leaving

Kosmeya is familiar to almost everyone. The sight of her bright colors immediately reminds of summer. The plant arrived in Russia from Mexico, where, by the way, it is still incredibly popular today. Note that the plant gets along well not only in warm climates, but also in the northern regions of our country.


This process cannot be called too complicated, but it has its own nuances. Perennial kosmeya is more often grown on lawns and flower beds. It is rarely used as cut flowers, but such cases still occur. Also undersized varieties are grown on balconies in pots. This plant is resistant to cold, light-requiring. Kosmeya is considered unpretentious. It is planted directly in the open ground in the spring. Annual species are grown in pots using a land mixture with the addition of sand and peat. The mixture is fertilized with minerals. If everything is done correctly, very soon you will be delighted with a beautifully blooming fresh cosmos.

What is necessary in order for a lush cosmea to please you with its flowering in the summer? Planting and care (photo of the plant in the article) will bring only positive emotions to the gardener if you follow certain rules for planting and propagating a plant. Better to plant it in the open sun in a mild climate. In hot summer, however, it is better to plant the cosmeia in partial shade. She does not tolerate low temperatures, if you do not create conditions for this (the ground must be mulched). In summer, perennial kosmeya needs regular and abundant watering.

In general, plant care comes down to regular watering and loosening the soil once a month. If you do not forget to water and weed the kosmeya, the result of your labors will be a lush and strong plant that will shade the flowerbed and make the overall appearance of the garden incredibly beautiful. If the soil contains a sufficient amount of fertilizer initially, it may not be re-fertilized. In cases where there is little fertilization, you need to add an additional portion during the beginning of flowering (the appearance of buds).


The plant reproduces by seeds, which can remain viable for several years. It often happens that the seedlings of the cosmos are thickened. In this case, it is better to thin them out. The beginning of flowering is in July, the end is during the first frost.In the fall, the stems are cut close to the soil surface. If you leave large, faded buds, you can get seeds.

One of the main advantages of the plant is its resistance to pests. Sometimes perennial kosmeya is affected by aphids. May also be affected by heavy rainfall. If the rains are moderate, and the gardener takes proper care of her, he will definitely be pleased with a beautiful cosme. Varieties (photos represent three different ones) are very diverse. Each of them has its own characteristics, which should be familiarized with on an individual basis.

Planting and caring for cosme in the open field

It should be figured out that the flower can be grown immediately in the open field, as well as sow bushes for seedlings. Let's take a look at both planting methods so you can figure out which method to use.

Sowing cosmos seeds in open ground

Growing cosmos from seeds is carried out immediately after the snow melts and the soil warms up a little. In the selected area, distribute the seeds of the culture in small nests (3-4 pcs.), Making a distance between plantings of 30-45 cm. Deep planting of seeds in the ground is not required, about 10 mm is enough. With this method of planting, the plant will begin to bloom in July.

Remember that the kosmeya flower reproduces well enough by self-seeding, in the spring you only need to plant the hatched seedlings.

Planting cosmos for seedlings

Growing seedlings of cosmos, you can count on a more reliable and predictable result. The optimal period for planting cosme seeds is March or April. Seed material is sensitive, so it is enough to evenly distribute it on the surface, slightly pressing it into the ground.

After that, the crops are moistened, and the container is covered with cling film, placed in a room with good lighting. It is important to adjust the optimum temperature, it should be between +18 and 20 ° C. Subject to all the rules, the first seedlings will appear in 1-2 weeks from the moment of planting. If the seedlings are too dense, it is recommended to thin out the plantings, the optimal distance between the bushes is 10-15 cm. You can also just plant the Mexican aster in separate cups.

At the beginning of June, seedlings of the cosmos flower are planted in open ground. The plot is chosen with good lighting, protection from the winds. The soil is chosen well-drained, moderately nutritious and slightly acidic. Too nutritious soils will lead to the fact that the green mass will begin to actively develop, and the flowering will be poor. For each plant, shallow holes are prepared (30 by 30 cm), then they are filled with water. After planting crops, they are densely covered with soil, re-watered. Tall varieties are usually tied to a support, a rod or long rail is used for this. The flowering of Mexican asters starts in late June and early July.

Rules for caring for Mexican aster

In garden conditions, the plant requires regular watering, this is done once a week. It is also important to regularly loosen the soil around the crop, removing weeds and revitalizing the soil. Experts recommend feeding the bushes well. During the formation of buds, they are watered with mullein and double superphosphate.

For lush flowering use a solution of the drug "Bud". It is necessary to pick off faded flowers in a timely manner.

Perennial kosmeya before wintering requires shortening the shoots. This is done at the end of flowering, it is recommended to shorten it to 15 cm. For the winter, the bushes must be covered with spruce branches. As you can see, planting and caring for cosmeia is not difficult, so even novice gardeners can do it.

I would never have thought that an ordinary kosmeya can grow and become a very fluffy and extraordinary herringbone. This summer my cosmos attracted the attention of all guests very much, since the whole garden was buried in the cosmos flower carnival) A drop of love, a little tasty feeding and the flowers are transformed)

In the spring, I did not bother with seedlings and planted three packs of seeds directly in the ground under a tree. The seeds have 100% germination, so I got a lot of seedlings. Half gave away to friends and half had to be built on their site.

This excellent plant is well suited for creating floral arrangements of annuals and covering up unattractive places, but I advise you to take into account its gigantic size when planting, as it grows over time and shades other flowers.

In this photo, the flowers are just gaining growth and strength.

And this is already the middle of summer)

By the fall, the kosmeya covered all the flowers in this flower bed. I had to tie these huge trees to the wall))

With proper care and good moisture, kosmeya grows very quickly. It has thick feathery foliage and many pink and white flowers. The plant is not demanding, but in a drought I watered all the flowers in the evening with a drip method.

The cosmos has short superficial roots, so in late autumn I easily plucked these giant flowers.

Now I have collected my seeds and next year I will definitely plant this beauty. I recommend the flower as a very hardy and unpretentious annual.

Kosmeya - flowers for any gardens

This annual plant has been popular for many decades not only all over the world, but also among Russian gardeners. They call him kosmeya. The flowers of this unpretentious plant adorn a huge number of personal plots. It got its name from the Greek word cosmos, which can be translated as "decoration". Kosmeya are flowers of the aster family. They can be grown in annual and perennial crops. This flower looks great on flower beds, lawns and green lawns.

The homeland of cosmos, whose flowers amaze with a variety of shapes and colors, is South America. There are 20 species of this plant in total. Despite its origin in warm climatic conditions, this flower grows remarkably in almost all regions of Russia, from the north to the middle lane and southern regions. This flower is practically not used for cutting, as it withers quickly.

Most often there are two types of cosmos: double-feathery and sulfur-yellow. The first reaches 1.2 m in height. It forms powerful bushes with tall, highly branched stems. The double-feathery cosmeya, whose flowers reach 10 cm in diameter, is most often colored pink, white or red.

This plant blooms in June-July and blooms before the onset of the first frost. Kosmeya are flowers that can withstand short-term droughts. It differs in its cold resistance. This flower is planted in well-lit areas, protected from strong winds. When planted in partial shade, kosmeya blooms poorly, but there will be much more leaves on it than in the sun. This plant is unpretentious, not demanding on the soil. It grows best on loose, well-drained soils that are not very nutritious. The plant loves moisture, so it needs regular watering.

Caring for this flower consists in weeding, watering, loosening the soil. Top dressing is done only when the kosmeya grows on poor soil, before budding and at the very beginning of flowering. Tall varieties need to be tied to a support, as their fragile stems can break in the wind. In the fall, the stems of the plant are cut off the very ground. Pruning faded flowers encourages abundant flowering.
