Rules for planting and caring for evening primrose in the open field, description of varieties

Decorative evening primrose attracts gardeners and landscape designers with its simplicity and variety of species. The perennial flower has a large number of varieties that are found in both the south and north. Most of them are of selective origin, but invariably include such a feature as bright numerous inflorescences. The popular evening primrose flower, the planting and care of which will be described later, is called primrose in botany. In addition, the plant is called a night candle or evening primrose.

Description and features

Evening primrose inflorescences are the main advantage of the plant, the flowers are white, yellow, red or blue, and also striped. The creeping rhizome produces hard, pubescent shoots, the height of which depends on the variety. The leaves are always arranged alternately, and have a variety of shapes. The peculiarity is that flowering occurs in the evening, and the buds do not close even in cloudy rainy weather. Evening primrose varieties have a one-year, two-year, or multi-year growing season.

Growing in the garden

Enotera is effortlessly grown in garden plots. The bush does not need to be repotted frequently, the plant does not require special feeding and sophisticated care. The flower perfectly coexists with other crops, has a strong immunity and tolerates bad weather conditions well.

Seedling method

Small evening primrose seeds are more suitable for seedling sowing. The usual seedling potting mix is ​​placed in small containers. In each, a small depression is made up to 5 mm and the seeds mixed with sand and earth are poured. The soil is sprayed with water to prevent waterlogging and decay. It takes up to 14 days for the emergence of seedlings.


You can sow evening primrose seedlings from January to March. The exact dates will be indicated on the seed package, as they depend on the variety. Seedlings are planted no earlier than the beginning of May. The soil should warm up well, be moistened with melt water and have time to dry out. It is advisable to protect young plants from possible frost..

Soil requirements

Soil composition is not particularly important for evening primrose cultivation. The varieties bloom beautifully on all types of soil, with the exception of poor heavy clays. The plant reacts normally to acidity, but grows more actively on neutral loose loams rich in nutrients.

Temperature regime

Immediately after sowing evening primrose, the containers must be tightly covered with polyethylene so that the seedlings receive a sufficient amount of heat.


After 8-10 weeks after sowing, the seedlings must be hardened. To do this, you need to take the containers outside during the daytime. The necessary conditions are sunny weather and no frost. You can start with 10-15 minutes and gradually increase the time spent in the air.


After 10-15 days, the seedlings must be thinned out. Excess shoots are carefully removed, but it is recommended to simply plant them in another container. Some of them will take root and are used for planting in the future. Thinning of plants sown in one large container is especially important.

Open ground transplant

By May, the seedling grows the required number of true leaves and has a developed root system. Plants are planted in moistened holes one at a time, completely immersing the roots in the planting hole. The distance between the bushes is at least 50 cm.

Seedless way

On light soils, such as sandy soils, it is possible to grow evening primrose from seeds in the open field. Before planting, they must dig up the earth, add sand and, if desired, add organic fertilizers. In the first year of planting, the plant will grow its root system and is unlikely to bloom.


Planting time significantly depends on the temperature of the environment. When the air warms up to 16 ° C, you can prepare the soil for planting seeds. After 14 days, they start sowing if the spring cold does not return.

Site selection

The main criterion for choosing a site for planting flowers is illumination. The degree depends on the variety, as there are plants that prefer sun, partial shade and maximum shade. The moisture content of the soil should not be too high, the flower tolerates a short drought more comfortably than stagnant water.

Seed planting scheme

Seeds are sown in groups at a distance of up to half a meter from each other, as evening primrose grows over time. The second landing option is tape. To do this, you need to make grooves up to 50 mm deep in loose soil, water with water, then pour out the seeds evenly and cover with soil. After that, the ground is lightly tamped.


Dense seedlings need to be thinned out to provide space for plants to grow. The sprouts are removed with a thin knife so as not to damage the roots. In this case, the surplus plants can be planted elsewhere.


Evening primrose is not a demanding plant to care for, however, the shrub should be provided with elementary conditions. These include:

  • timely abundant watering;
  • weeding weeds;
  • fertilization;
  • pruning dry parts of the plant;
  • loosening the soil;
  • mulching;
  • tying up.


Evening primrose prefers well-moisturized soil and reacts negatively to dry, sunny weather. To achieve the maximum flowering level, it is necessary to water the plants at least 2 times during the growing season. For each square meter of planting, 15 to 20 liters of water are required.


It is regularly necessary to loosen the primrose root circle in order to remove weeds and increase the access of oxygen to the roots. An abundance of weeds leads to poor growth and poor flowering, and also contributes to the spread of fungal infections and pests.

Top dressing

Low requirements for soil fertility allow you to fertilize evening primrose 1 time during the growth period. There are 2 options for applying top dressing to the soil:

  1. During flowering, the soil is enriched with potassium sulfate and superphosphate at the rate of 15 mg of dry matter per square meter.
  2. At the stage of bud formation, add wood ash powder or nitrophosphate to the soil.


Immediately after the end of flowering, sluggish peduncles must be removed from the plants. This increases the nutritional level of the greenery and helps keep the flower bed attractive. At the end of the growing season, which usually occurs in late autumn, the withered shoots are cut along the ground line.


Long-term cultivation of evening primrose in one place leads to degeneration, shredding of flowers on the growing bushes. At the first signs of deterioration in the appearance of the inflorescences, the plant must be divided by dividing the bush and planted in another place. The procedure is carried out infrequently, the period of stable growth should be at least 4 and no longer than 5 years.

Preparing for winter

Additional shelter for evening primrose is not required for the winter, as the flower is frost-resistant. Before the onset of frost, the aboveground part of the plants is cut off, and then abundant mulching of the planting area is carried out. The protective layer must be 50 mm high. Chopped peat, compost, spruce branches or fallen leaves will optimally preserve the roots.

Diseases and pests

Evening primrose has good immunity, especially rarely amenable to infection with fungal infections. When spots appear, you need to remove the damaged leaf and destroy the neighboring plant, which was the source of the disease. Fungicide treatment and preventive spraying are not required. Insects attack evening primrose much more often. The main danger is aphids, which must be destroyed with insecticides immediately after they appear.


There are several types of reproduction of evening primrose: seed and vegetative. In order to get your own seeds, you need to keep the inflorescences until the fruit forms and the seed ripens. However, if you skip harvest time, evening primrose will dissipate naturally. In the fall, it is recommended to propagate the bush vegetatively.

Self seeding

Evening primrose reproduces well on its own by scattering seeds. This method is natural for annual species. Seeds around the plant fall out of the fruits in autumn, and fresh shoots appear in spring. It is required to thin them out or transplant them to the right place.
Dividing the bush

This is the easiest way to reproduce evening primrose, which is already growing in the garden. In this case, it is not necessary to dig out the entire bush, you can cut off a part with a shovel and transfer it to a new place. For fast rooting, it is necessary to keep a lump of soil on the cut off rhizome. Reproduction is possible both in spring and autumn.

Application in landscape design

In horticulture, externally excellent evening primrose varieties are planted in contrasting combinations. The bushes will create bright areas on green lawns, look good in flower beds with constant partial shade. Plants adorn the northern slopes of the alpine slides, fill in and mask flaws well. In the design of the borders and the foreground of the flower beds, low-growing varieties of primrose are used.


To form a contrasting bright effect next to evening primrose, it is preferable to plant:

  • lobelia;
  • ageratum;
  • veronica;
  • astilba;
  • bells.

These flowers have different shades from the primrose when flowering, and the leaves differ significantly in texture.

Healing properties

Enotera is often used in folk medicine due to its rich chemical composition. The rhizome serves as the basis for the preparation of decoctions against respiratory diseases and tuberculosis. Oil is squeezed from the seeds of the plant, which prevents thrombosis of blood vessels, and is also used to treat eczema, dermatitis, diabetes, cirrhosis and rheumatism.

Infusion of the green part of evening primrose is an effective anticonvulsant agent, is a part of folk remedies for heart and kidney ailments, has an antimicrobial effect when used externally.
