Diseases associated with the endocrine system. Endocrine system

Once I bought bags of seeds "Yellow chamomile", "Red ro-mash-ka", "Blue chamomile" in the market. I was aware that there were no yellow garden daisies as such, but for the sake of curiosity I still bought it, especially since the flowers were presented as perennials.

Coreopsis was hiding under the name "Yellow Daisy". Coreopsis - perennial herbaceous plant with erect shoots from 30 to 90 cm high. The size of the flower in diameter is about 6 cm. Coreopsis blooms profusely in July and continues to bloom with double inflorescences-baskets of bright golden yellow color until frost. Looking at the blooming coreopsis, it seems that the sun has settled in your garden.

Coreopsis blooms just at the time when other perennials bloom: roses, lilies, delphiniums, rudbeckias. The garden turns into a blooming fragrant paradise! Gradually, annuals are being pulled up to the flowering of perennials. At this time, you do not want to leave the garden at all! And one more note: some perennials bloom once, some of the perennials bloom again in August-September, then unlike them coreopsis does not stop its flowering until the first frost.

coreopsis seeds Can sow on the windowsill for seedlings in late March, in the greenhouse - from mid April, and directly to open ground — in May. The only difference is that when seeds are sown in March, flowering can be obtained in the same year, and when seeds are sown later, coreopsis will bloom only next year.

Coreopsis seed germination is very high. When coreopsis seedlings have 2-3 true leaves, the plants need to be planted. Coreopsis is planted in a permanent place in the ground in early June, when the threat of frost has passed. When planting, it is recommended to follow the planting scheme: plants are planted at a distance of 20x30 cm from each other.

Coreopsis does not like excess moisture., he is quite comfortable on moderately dry loose fertile soils. The best place for planting coreopsis - open sunny places.

Coreopsis is a very winter-hardy plant. Under the snow, the leaves in the rosette remain green until spring. However, if the coreopsis landing site is blown by the wind in winter, then you should not neglect at least a light shelter from dry leaves.

In one place, coreopsis can grow for a very long time, but once every 3-4 years, the coreopsis socket needs to be divided and replanted.

Coreopsis are very diverse. There are undersized varieties that will look best in a flower garden or mixborder in the foreground. They can be planted in containers, boxes to decorate windows.

Higher grades look great in a flower carpet annuals. By the way, the coreopsis flower is very similar to the yellow cosmea, and sometimes they can be distinguished only by the leaves. The tallest coreopsis are planted in the background of flower beds. For planting coreopsis it is better to use group landings.

By the way, coreopsis flowers stand in water for a long time, so they can be safely used in teams. bouquets. Even a few Coreopsis flowers placed in a vase at home will add sunlight, warmth, will cheer you up, they are very cheerful!

An adult socket of coreopsis is recommended to be divided in April-May or in autumn, in September. Plants take root easily. Low-growing varieties of coreopsis can be transplanted even in a flowering state. The only condition: before transplanting, water the plant strongly and then plant it “in the mud”. So you hurt less root system. And it also reproduces very well by self-sowing, then you get tired of removing the rosettes of coreopsis from the flower garden here and there))

Coreopsis, like other perennials, can be affected by diseases and pests. The most common coreopsis diseases areleaf rust, fusarium, various spots on the leaves. Affected leaves must be cut off. Spraying with fungicides usually helps, but if the appearance of the plant has not improved even after the treatments, then it is better to completely remove it from the flower garden so that the disease does not spread to other flowers.

You should also do it with various viral infections, when the appearance of the plant is very deplorable: the plant itself is stunted, the tops of the peduncles begin to curl up into a tube. You will never expect flowering from such plants.

Coreopsis can be affected by aphids. If manually or folk remedies get rid of aphids fails, then you need to resort to treating plants with aphid preparations. Various caterpillars, beetles can be removed manually when visual inspection plants.

You can diversify the landscape design of the garden with the help of border and bouquet plants. One of the species is presented in the description on this page. You can learn about Coreopsis flowers, which are a genus of flowering plants in the Compositae family. There are also folk names this flower has calyopsis and a series, there are also common name with various other plants.

The name of the flower coreopsis comes from the Greek words κορις - "bug" and ὄψις - "view" (meaning the shape of the achene). used as food plant for some species of caterpillars, Lepidoptera (including Coleophora acamtopappi). Also, the seeds of the plant are very often devoured by birds, which are not at all embarrassed that outwardly they look more like ticks than food. You will notice this yourself if you place the seeds in an open place in winter - for example, goldfinches are very often used as a source of food. All Coreopsis species have been designated as Florida's state wild flowers in the United States since 1991.

Description of coreopsis with photos and basic botanical characteristics

Further it is proposed general description coreopsis with brief botanical characteristics that allows you to draw necessary knowledge for growing it from seeds in the garden. Plant height varies from 40 centimeters to 1.2 meters. They tend to grow in the form of dense bushes. The fruits are flat and small, when dry, they can look like bedbugs. Many varieties this plant grown in gardens as one of the main decorations in the garden, or in large flower arrangements. 28 plant species can be found on the territory North America, Central and South America.

The flowers are usually yellow with a serrated tip. They have spectacular flower heads wrapped on both sides with eight petals. Many gardeners mention their superficial resemblance to field daisies with their tall stems and flowers that are usually even taller than the foliage. Unfortunately, this is where their similarities end.

The leaves and petal colors of coreopsis vary depending on the species:

coreopsis grandiflora has bright yellow petals on tall stems that bloom throughout the summer;
coreopsis pink is distinguished by its finely textured leaves and pink flowers with a yellow centre;
coreopsis vertikylata is gaining popularity, which is so called because of the special carving on the surface of the leaves (which are also very thin). The flowers are very thin, but bloom profusely.

More recently, another variety was bred - coreopsis red: photos show the beauty of this plant:

Growing coreopsis from seeds: planting and caring for the plant

Due to low performance, drought tolerance and long flowering, the plant is very often used as a border in flower beds in a sunny position. Growing coreopsis from seeds is the most commonly used type of propagation, especially since the care of the plant is not difficult.

After planting, young seedlings should be carefully watered until they are established - after that they are quite resistant to drought. Many of the flowers do not loosen well, so it's okay if you cut them off, but only after the first wave of flowers has disappeared. They will recover fairly quickly. If you notice that the bush began to bloom very little, this is a signal that it urgently needs a transplant (usually it is produced no more than once every 3-5 years).

The temperature regime required by the plant varies depending on the variety and type of plant, because not even all coreopsis varieties are perennials. Many varieties that have been recently bred have not yet been tested for hardiness.

Also from external conditions, as well as the type and age, the size of the bush will also depend. It will bloom best in full sun, but you can grow Coreopsis in partial shade just as well. Plants can get a little skinny in partial shade, but they will adapt over time. In areas with intense drought and hot weather, coreopsis prefers to rest in the afternoon shade for some time.

Most Coreopsis strains are very easy to grow from seed without much concern for soil quality and acidity. You can plant seedlings - this must be done indoors a month and a half before the last expected frost. And you can sow them already in open ground. All varieties of coreopsis, except hybrids, are able to reproduce independently. Planting coreopsis for seedlings is carried out in light structured soil at home at the end of February. If organized proper care for coreopsis at this stage, then by May you can get magnificent flowering bushes that are suitable for border groups and landscaping balconies and loggias.

It is necessary to pick seedlings in the phase of 2 true leaves. To do this, you can use peat pots with a diameter of up to 10 cm.

The following are more photos of coreopsis of various colors and in various stages of development:

Coreopsis varieties with descriptions and photos

All varieties of this plant are very popular with gardeners - and yet there are not so few of them, at least a hundred pieces. The following are coreopsis varieties with photos and brief characteristics, which will allow you to choose the right variety for the garden.

Coreopsis whorled - bushy, elegant and branched

Coreopsis whorled is a bushy yet very elegant and branchy perennial with three partly open threadlike leaves arranged in opposite pairs or triplets.

The flower heads are about five centimeters across and both flowers (disk and ray) are yellow. The flowers grow prolifically in loose clusters on thin, veiny stems from early summer until the first frost.

The most popular variety "Moon Bundle" grows up to 60 centimeters in length and has small inflorescences of a light yellow hue, 2.5 centimeters in diameter. They bloom profusely on lacy foliage.

In nature, coreopsis whorled is found in the southeastern United States - in the states of Virginia, Maryland, Tennessee, Arkansas, and also in North Florida. There you can meet them in dry and thin forests on open pine lands.

To maintain the health of the plant, we advise dividing the roots every three years. It is in this way that coreopsis whorled most often reproduces - usually in winter or early spring.

The color of the petals is bright yellow. Height varies from 18 to 25 centimeters. The flowering period is from mid-summer to early autumn (sometimes earlier).

It occurs naturally in the southeastern United States in sunny meadows and roadsides. At least occasionally it is necessary to give the plant sunbathing.

Since coreopsis grandiflora tolerates low-fertility soils and withstands intense heat, it often manages to take root in urban environments, and even in gardens located on rooftops (a very common occurrence in Lately). It is also able to tolerate the salt and wind of a maritime climate. If the lumps of the plant do not divide, then usually the flower does not live longer than two to three years. The beauty and grace of flowers are shown in the photo:

Coreopsis dye: yarn dye or hot drink?

Coreopsis dye is the most famous of the annual varieties. It is often found in Canada, Northeast Mexico, and much of the US (especially the Great Plains and the Southern states, where it is often referred to as "calyopsis"). It often grows in turbulent areas - for example, near roads and fields.

The bush grows quickly enough and reaches a maximum growth of up to one meter (minimum - only 30 centimeters). The leaves are pinnatipartite, glabrous and tend to a thin, upper part of the plant, where numerous flowers, 4 centimeters in diameter, sit on thin stems. The flowers are shiny and yellow with a maroon or brown center. different size. Blooms from mid-summer. Small, thin seeds begin to germinate in early autumn (winter in a low rosette) or early spring.

In production, this variety is used to obtain dye for yarn, and was previously used as a hot drink. Many women believed that if you use this bush for food, then they will definitely have a girl.

Was introduced to Japan as decorative look, after which they are actively used in landscaping projects - along the banks of rivers and railways.

The stem is 15 centimeters long and the single inflorescences grow on stiff 60 cm stems. All available flowers are mostly yellow, but some have maroon or brown spots on the rays, some have darker leaves, and some are species dwarfs.

It produces flowers even in poor soil, which is not too rich in organic matter. In very fertile soils, bushes grow more foliage and fewer flowers. Moderate watering, can tolerate slight droughts.

Coreopsis pink

Coreopsis pink is found in eastern North America, in a number of Atlantic states, as well as in Nova Scotia and Canada. It grows well in rooms with high humidity and in swampy areas.
