Clarkia: Description, Landing and Care

Clarkia is a genus of annual plants that delight gardeners with their lush and abundant blossoms all summer. His name culture was received in honor of Captain William Clark, who in the XIX century brought plants from the California coast to the countries of the Old World.

To date, there are over 30 varieties of culture.


In the natural environment, Clarkia is found in the northern part of the American continent, as well as in Chile. Culture is an annual plant, which, depending on the variety, is medium- or tall – its length varies from 35 to 90 cm. Stems upright, very branched, richly pubescent short, but dense darishes. Leafy plates of bright green colors, can have a naiz. Extension shape, oval, Location of sheets alternate. The flowers are stuffed, can be simple either terry, diameter reaches 3 cm, coloring can be the most diverse. Usually they are going to the inflorescences of a collective or a creeping type, a single location occurs rarely. Petals can be solid or three-bladed, a cup usually tubular. Fruit – Multi-Sampling Box Extracted Shape.

What is different from year?

Clarkia is very similar to year, the similarity is so strong that some nerds even for a long time considered these cultures with a kind of one and the same plants. However these are different cultures.

Claria has small flowers, like miniature roses, as if strung on the stalks-twist. For the year, the flowers are quite large, elegant, satin – the size of each is 6-8 cm, they are terry or simple. And the same culture can have a wide variety of shades: white, pink, as well as scarlet, purple, lilac and bluish.

The height of the bush differs. Clarkia grows up to 30-90 cm, while the length of the stem of year does not exceed 30-40 cm.

Despite the differences, gardeners often plant these plants together. They argue that cultures harmoniously complement each other in the flower bed.

Types and varieties

Today, there are about 35 varieties of Clarki, but interest in breeders cause only four varieties – they are the base for obtaining a large number of decorative garden forms.


The height of this annual bush comes up to 36 cm. Stems branched, leafles elongated, dark green. Flowers terry, diameter is 3-4.5 cm, can have a wide variety of shades: from pure white to deep carmine.


Another beautiful plant that is distinguished by lush color. The height of the stems – up to 75 cm, the flowers are stuffed, in most cases terry, can have a wide variety of coloring. This type is universally used to decorate the club, it looks beautiful in group and single landings, often used under the cut.


Among the gardeners are more known as lowered. This is a low-speed species that grows only up to 40 cm. Leaf plates extended, narrow, solid, at the end are pointed. Flowers are small – up to 3 cm in size may be terry or simple. Their distinctive feature is the separation of petals for 3 shares. Tint palette is the most diverse. Flowers are formed one or small groups in the sneakers of sheet plates. Clarkia pretty usually blooms before the rest of his “sisters” for a couple of weeks.

Due to the original form of petals in the USA, this variety is often referred to as “Elk Horn”. It was he who became a base for removing the ariana variety, which is very in demand in flower flower. A feature of the variety is the two-color flowers of white and purple shades, the height of the bush – 40-50 cm.


The second name “Nogotkaya”, in the natural environment found in California. The height of the bush is 50-90 cm, the stalks are pretty durable, branching, near the base it is treated, but at the same time thin. The leaves are dark green, have a characteristic gray-tide, a shape of a slightly elongated, the edge is rarely. Characteristic reddish bodies are noticeable on leafy plates. Clarki flowers of this form are small -3-3.5 cm, collected in cystic inflorescences. Tint palette is rich: There are bright-scarlet, milk-white and gentle-pink varieties. The first flowers appear in mid-June and please their owners until October.

Clarkia Elegant has become a “parental culture” to eliminate several sought-after varieties:

  • “Albatross” – this is a bush tall 6-7 cm with snow-white velvety flowers;
  • Salmon Perfection – tall plant with a length of 90-100 cm, terry flowers, pale pink;
  • “Sun” – a grade growing up to 65-70 cm, salmon flowers, grow in the sinuses of the sheet plates by one way;
  • Orange – Corpoil bush 55-65 cm long, deep orange flowers.

Most popular with domestic gardeners enjoyed Clarki variety “Joy”. Her reprehension branching stems grow up to 50-60 cm. Diameter of flowers – 3-4 cm. Blossom begins in June, the plant is covered with flowers abundantly from bottom. Tint palette can be the most diverse: from saturated pink to raspberry shades.

Not less love is a diamond grade, It is a branching lush bush height 65-80 cm. It blooms very abundantly and for a long time – from the first numbers of July and up to the end of September. Velvet flowers, coloring – red-pink.

Growing from seeds

Optimal deadlines

In the spring, sowing is best practiced in the first half of May, in which case the first bloom can be waited already in mid-July, and it will last until the end of September.

Autumn landing is allowed, while seedlings are placed in open ground in late September. As a rule, by the time of the start of frosts, the sprouts have time to grow and in this state can already be overwhelmed under the shelter. With autumn plant planting, you can achieve much earlier – already in the first days of June.


Traditionally, Clarki is grown by a seed way, it can be a reckless or either. In the first case, the seeds are planted directly into the ground. Before sowing seeds, it is very important to prepare a plot: it is best to make a peat in advance in a proportion of 1 kg / kV. M., as well as 1 st. L. Superphosphate and potassium sulfate (on the same area). The substrate with nutrients prepare at least a couple of weeks before the start of landing.

Seeds are placed in the wells of 4-5 pieces in each, the distance between the pits is kept at a level of 30-40 cm.

Seizians do not need too plunge – it will be enough to press them to the soil and send the earth a little bit.

The first shoots appear already after a couple of weeks, during this period they can be divened, but it is not necessary to get involved in disadvantaged, because the blooming Clarkia in a thickened landing will look much more effectively.

Seeds can be planted in autumn, shoots are perfectly preserved under the layer of snow, but even if the seedlings do not have time to germinate before the start of frosts – there is nothing dangerous in this, in early spring, as soon as snow comes out, they go up together, and you will only go to the landing.

Care for seedy

When cultivating Clarki, a decide on the very first stage of its life cycle, the plant is protected from fluctuations in temperature, return frost and cold shower. That is why most of the flower arrangements still prefer to grow seedlings first, and not plant seeds directly into the ground. Usually these works start in March, then you can achieve flowering in early June.

Clarki seeds are placed in a weakly acidified substrate, slightly applied to a plate, sprayed with water from the sprayer, covered with a polyethylene package or glass to create a greenhouse effect, and then put in a light warm place, but keep in mind that direct UV rays do not penetrate there. Only the very first sprouts will appear – the greenhouse can be removed, But the container itself before moving seedlings to the open area should be placed in a dry heated place, be sure to high-quality ventilation.

When the seedlings are formed the first full-fledged leaves – it should be picked.

Landing in open ground

Clarkia is a light-loving culture, but at the same time it can grow well and develop in light half. This plant needs a space, as it grows pretty quickly.

It is very important to choose the right place for the culture – such that excludes drafts, otherwise shrub stems can break.

Best Flower develops on the fertile land of medium or light density. Of course, this plant is extremely unpretentious and can grow on loam, but then bloom will be scarce and short.

For future seedlings, it is necessary to prepare an earthen mixture: take a universal substrate for seedlings and add to it overwhelmed with a clean river sand, as well as peat in the same quantities.

In order to reduce the risk of infection with fungal infections, the prepared land can be calcined in a preheated oven or disappear on a water bath.

Clarkia Locking on open areas is made in May. If the land is not suitable for culture due to the inconsistency of the hydrogen indicator, you can acidify the substrate. For this, 60 grams of sulfur / square. M. either slightly watered with citric acid solution (from the calculation of 1.5 st. L. on the water bucket). If the Earth, on the contrary, is too acidic, then before the landing works it is necessary to limize. Fat primer should additionally mix with sand.

Clarki landing is produced in the following sequence: first from the container get young seedlings, but not one by one, but in small groups. You need to take them together with a coma and land in the wells, voids are filled with a substrate prepared in advance. The distance between the wells is kept at a level of 30-40 cm, near each plant should stick a stick or a regular rail – in the future it will serve as a refined stem.

Different varieties are best planted at a short distance from each other, then they will be able to reset together.

How to care for?

In order for Clarkia for a long time pleased you with their healthy and lush flowering, you need to stick to simple rules for the care of this plant.


In hot summer weather without abundant sediments, Clarki requires regular moderate watering as the soil drying – usually they do twice a week. However, keep in mind that it is impossible to pour the plant in any way, otherwise the roots will start. For that To prevent this unpleasant phenomenon, it is best to plant a culture in well-drained land.

Wet substrate should be slightly exploded – thus improving the inflow of air to the roots.

If the weather stands rainy and cool, then watering better completely stop.

Water should be pouring directly under the bush, not allowing fluid from entering the leaves and flowers, otherwise burns may appear under the rays of the sun.


Clarki feeding should be made twice a month, especially at the stages of bootonization and flowering. It is best to use ready-made mineral complex compositions that can be bought at any store.

The use of the organic is not recommended.

Especially needed by this plant feeding in arid, lowbotting weather. In order to achieve more magnificent flowering, you can add a little unwound wood ash to the ground.


So that blooming is longer and spectacular, all fading inflorescences must be deleted in a timely manner, otherwise the plant will simply have no vitality in order to give new flowers.

The same applies to fading dried stems, shoots and branches.

Collection of sowing material

Clarkia has a property of multiply by self-sowing, so at the time of blooming you need to choose 3-4 large flower, after pollination, wilts and at the very beginning of the formation of the fetus should be carried out by “insulation”. For this, the fruit is wrapped in a clean bandage and fix it to the stalk, but not too tight. Thus, Seeds ripen, but march does not allow them to fly out – this eliminates the risk of self-seeing.

After fading a flower seed material matures around a month, ready-made boxes look dark brown, they need to be collected and added naturally, and then put for storage in paper envelopes or match boxes.


Clarkia is characterized by high frost resistance, but with autumn planted, so that the flower is preserved better, it must be coated with mulch (you can use moss, fallen leaves, hay or coniferous needles).

In all other cases, it is necessary to cut all parts of the bush in the fall and dig roots in order to prevent the development of fungal infections in the ground.

Diseases and pests

Culture is characterized by high resistance to disease and insect pests, nevertheless, some care errors can cause the appearance of fungal and viral infections, in particular, if we plant a culture on a subline earth, it often leads to the appearance of rust. A fungal infection shows itself in the form of yellowish-brown spots with a clearly defined edging on the leaves. In most cases, pathology becomes a consequence of the oversupplication of moisture or excessive introduction of nitrogen-containing fertilizers. For resuscitation, it is best to use fungicidal preparations, for example, a good effect gives a Bordeaux liquid, spraying produce twice a day.

Excessive moisture often provokes the occurrence of false mildew, in which case dark or colorless rounded spots are formed on the back of the sheet, and the leafy plates themselves are deformed. To combat fungus, use any fungicides.

Much danger to Clarkia presents such an insect as a torment Cherver. Rarely, but in the surface of the green parts of Clarki may appear, and in fact, and in another case, insecticides can be used to combat.

With excessive oveurgement, flower midges often appear near the flower, especially often it happens at room or balcony cultivation. The greatest danger is not insects themselves, but their larvae that feed on roots. In the event of an attack of pests, the plant needs to be transferred to another pot, having previously treated from midges.

For the prevention of their appearance, it is necessary to loosen the land from time to time near the bush, and before planting it is necessary to form a drainage layer.

If the preventive measures did not help and the midge still appeared, it is easiest to fight her with the help of ordinary matches. To do this, they are inserted into the ground with a sulfur head – 5-8 pieces around each bush. As soon as sulfur melts – manipulations repeat, usually grabs 3-4 treatments. Alternatively, a light pink solution of potassium permanganate or a weak solution of the economic soap can be used.

High efficiency has a chemical pencil from cockroaches and other home insects, for example, “Masha” – it must be grateful and sprinkle the land near the plant. Many insecticides such as “Bazedin” and “Mogyohed” are very quickly coping with unseassed insects.

Usage in landscape design

It looks very impressive for the beautiful Clarkia in the group composition. Especially popular such varieties like Sakura, Madmoiselle and Grace.

Most often it is planted near the walls of houses, fences and garden tracks.

Very beautiful this culture looks on balconies and loggias.

Clarkia Elegant harmoniously fits into flower discounts and becomes a real garden decoration.

Flowers are planted as one by one, and next to other blooming plants. So, a very spectacular ensemble is obtained when growing culture with peonies, as well as roses, flocks, daisies and dolphinium.
