Clarkia flowers: planting and care in the open ground, types and varieties with photos
Clarkia (Clarkia) is an annual herbaceous plant belonging to the family Cypress. This genus is very close to goodecium and some botanists combine these two plants into one genus. Clark, who in the 19th century brought him to Europe from California. In nature, this plant can be found in Chile and in the western part of North America. This genus unites about 30 species, while only 3 are cultivated.
Clarkia is a grassy annual, the height of which can vary from 0.3 to 0.9 meters. On the surface of erect branched shoots very often there is pubescence, consisting of short villi. Seated alternately located leaf plates have an oval-elongated shape and a light gray or deep green color. Sinuous flowers can be terry or simple, they have the right shape, in diameter reach 35 mm. And they can be painted in various color shades. As a rule, they are part of apical inflorescences having a racemose or spike-like shape, however, lonely flowers are sometimes found. The flower has a tubular cup; the corolla includes 4 three-lobed or whole petals, tapering at the base into the marigold. The fruit is an elongated polysperm.

Clarkia seed cultivation
Such a plant is grown from seeds in two ways: seedling and through seedlings. If cultivation is carried out in a seedlingless manner, then the seeds are sown directly in open soil. Sowing is carried out in April or in the first May days, and this can also be done in late autumn before winter. When preparing the site for sowing, for every 1 square meter for digging, you need to add 1 kilogram of peat and 1 large spoonful of superphosphate and potassium sulfate. The seeds of the plant are quite small, they are sown with nests of 4 or 5 pieces. In this case, the distance between the nests should be from 20 to 40 centimeters. It is not necessary to dig seeds into the soil, they should only be pressed down a little and sprinkled with a thin layer of soil. The first seedlings may appear within half a month, and you will need to thin them, however, it should be borne in mind that during flowering, the clarkia looks much more spectacular in a dense bush. If sowing was done in the fall, sometimes seedlings also have time to appear before winter comes, while they are well preserved under snow cover. When the seedlings appear in the spring, then they will need to be thinned out like a carrot.
Growing through seedlings
If clarkia is grown through seedlings, then young seedlings will be reliably protected from cold rains, frosts, sudden changes in temperatures and strong winds. It is recommended to sow seeds in March, in this case flowering at Clarkia will begin in the first days of June. Sowing seeds is made in a slightly acidic substrate. It is unnecessary to deepen them, but it is only necessary to press down with a tablet and pour from the sprayer. Cover the container with glass and put it in a warm and bright place, but there should not be direct sun rays there. After the first seedlings appear, the shelter should be removed. The container should be kept in a dry, warm place with good ventilation at all times. A pick is made very early, after the appearance of the first true leaves.

Clarkia planting in open ground
What time to land
Clarkia is transplanted into open soil in May. In the event that the soil on the site does not have a pH suitable for the given plant, then this can be corrected. In order to acidify the soil, you can use one of three ways:
- on 1 m2 add 1–1.5 kilograms of peat;
- on 1 m2 add 60 grams of sulfur;
- water the soil with a solution consisting of a bucket of water and 1.5 large tablespoons of citric or oxalic acid.
In the event that the soil is excessively acidic, lime is added to it. If it is greasy, then this can be corrected by making sand for digging. It is also necessary to fertilize the soil, and about what fertilizers to use for this, it is said in the section on growing clarkia in a non-seedling way. Site preparation should be done at least half a month before planting.
How to plant
It is not necessary to plant seedlings one at a time, but take plants from the container in small groups together with a lump of land. Then this group is planted in one well. It should be borne in mind that the distance between the holes can vary from 20 to 40 centimeters. Adult plants will need support, since they have very thin shoots, so do not forget to stick a long rail or stick near each hole. Different varieties of clarkia should be planted away from each other, since there is a high probability of their pollination. When the bushes are planted, they need to be watered and pinched a little so that they grow more bushy.
It’s relatively easy to grow Clarkia, and even a beginner can easily cope with this task. Watering should be done only when there is a long, dry, hot period. In this case, watering should be done only a couple of times every 7 days. At other times, such flowers will have enough rainwater. When watering, it should be borne in mind that the liquid should be quickly absorbed into the soil, and not stand for long around the bush. Top dressing should be done only during the formation of buds and flowering, and it is recommended to use complex mineral fertilizer for this. Frequency of top dressing - 1 time per half a month. Of fertilizers, it is recommended to use Rainbow or Kemira, while organic matter can not be applied to the soil. To bloom was long and magnificent, it is necessary to remove fading flowers in a timely manner.
Diseases and pests
Of the harmful insects, a mealybug can settle on clarkia. It is possible to understand that the bush is infected with this pest by the presence of a wadded cotton-like coating, which can be located on the aerial part of the plant. To destroy this insect, it is recommended to treat with confidor, actar or phytoerm.
In the event that on the site where the clarkia grows, the soil is loamy, this can contribute to the development of fungal disease. The fact that the bush is infected can be understood by the specks of rusty-yellow color, which have a brown border, which are placed on the sheet plates. To get rid of this disease, you should treat the bush with a fungicidal agent (oxychrome or Bordeaux liquid). If you plant this flower in a suitable soil and properly care for it, it will have a very high resistance to both diseases and harmful insects.
This plant is able to reproduce without your participation self-seeding. In spring, you only need to carefully thin out the seedlings. If you need seeds, then they can be very easy to collect. When the plants bloom, you will need to note the most spectacular flowers. When they begin to fade, then they will need to wear gauze bags. Seeds will become ripe 4 weeks after the flower withers, while the color of the box should become brown. Cut the boxes and sprinkle the seeds on a newspaper. These seeds can be sown before winter or sprinkled in a bag of paper, where they will be stored until the next spring.
When Clarkia blooms, the bushes can be cut to the ground surface if desired. And during the autumn digging of the site, it will be necessary to remove the remains of plants and burn them. Throwing them away is not recommended, as pathogenic microorganisms or fungi may appear in such plant debris.
Types and varieties of Clarkia with photos and names
Gardeners cultivate only three types of clarkia, namely: clarkia marigold, or elegant clarkia; the clarkia is pretty, or the clarkia is pubescent; Clarky Breveri.
Clarkia is elegant, or marigold (Clarkia unguiculata, Clarkia elegans)
This species in nature can be found in California. A branchy lush annual plant in height can reach 100 centimeters. Thin enough powerful shoots from below lignify. On the surface of oval greenish-blue leaf plates there are red veins, the edge of them is unevenly serrated. The flowers have a regular shape and a four-centimeter diameter. They can be terry or simple and have a different color: red, pink, white, purple and blue. They are placed one at a time in the leaf sinuses. Germination of small seeds lasts about 4 years. It blooms luxuriantly in July – September. This species is often grown in mid-latitudes. The varieties that are most popular are:
- Albatross. Terry flowers have a white color. A branchy bush reaches a height of about 0.75 m.
- Purplekenig. Terry flowers have a carmine color and a diameter of 35 to 40 mm. The bush in height reaches from 0.8 to 0.9 m.
- Salmon perfection. Terry flowers are painted in salmon pink and have a diameter of about 35 mm. The height of a loose bush is about 0.9 m.
Clarkia pretty (Clarkia pulchella)
This species is dwarf. Upright branchy shoots can reach a height of 0.4 m. Long narrow narrow leafy plates have a green color. They are pointed to the top, and narrowed to the petiole. Flowers can be terry or simple. They can be located both singly and be collected in small groups in the leaf sinuses in the upper part of the stems. Of particular interest is the shape of the petals, which are divided into 3 lobes, arranged quite widely. In this regard, in America, this species is also called "elk horns." Flowering begins half a month earlier than at clarkia graceful.
Clarkia Breveri (Clarkia breweri)
Recently, this species is becoming increasingly popular among gardeners. This annual cold-resistant plant in height can reach up to half a meter. The shape of the flower is similar to a butterfly, and in diameter it reaches about 30 mm. The flowers have a pleasant strong smell and are part of loose inflorescences. The Pink Ribbons variety has pink flowers with petals resembling ribbons; a bush can reach a height of about 0.3 m. The shoots of this variety are branched, and it blooms very luxuriantly.
Other types of clarkia cultivated by gardeners are actually goodetsia.
