Enotera biennial (lat. Oenothera biennis) - a representative of the Enotera genus of the Cyprian family. Also, the plant is called Flight, Biennial Donkey. In nature, the species is found in North America, Primorsky Territory, and the Caucasus. Typical habitats are roadsides, river banks, floodplains, and embankments. A decorative type, used in gardening, it is also actively used in breeding work.

Characteristics of culture

Enotera biennial is represented by biennial plants, which in the process of growth in the first year form a lush rosette of foliage, and in the second year - a racemose inflorescence. Basal foliage petiolate, elliptical, whole-edged, sharp at the tips. Stem foliage, on the contrary, is sessile, wide, lanceolate, endowed with a jagged edge. The foliage is green. The bushes do not exceed 130 cm in height.

The flowers are small, do not exceed 5-6 cm in diameter, have a lemon or yellow-lemon color, collected in racemose inflorescences. Flowering is long, begins in the first or second decade of June and lasts until the onset of frost. It should be noted that the flowers of evening evening primrose are fragrant, the variety called Evening Dawn is famous for its especially bright aroma. By the way, it also boasts an interesting golden color with a reddish tint.

Growing features

Biennial evening primrose is not very demanding on growing conditions. It can be planted both in sunny and semi-shaded areas with diffused light. However, the culture will bloom most magnificently in the open sun. The soil is preferable light, air and water permeable, nutritious, sandy, the optimum pH level is 5-7. Biennial evening primrose with waterlogged, saline, swampy soils will not make friends. Also, the plant has a negative attitude towards lowlands with stagnant cold air and precipitation.

Biennial evening primrose is grown most often in a seedling way. Sowing seeds for seedlings is carried out in the third decade of February - the first decade of March. Sowing is carried out in seedling boxes filled with a nutritious moistened substrate, always under film or glass. By the way, they are regularly removed for airing crops and watering. The seeds are not buried too deep, because they are of an insignificant size.

Diving is carried out with the appearance of 2-3 true leaves on young plants. Landing in open ground is carried out after the threat of spring frosts has passed. It is imperative that hardening is carried out before planting. The optimum distance between plants is 30 cm. Before planting, the soil must be thoroughly dug up, loosened, complex mineral fertilizers and, finally, rotted compost must be applied.

Culture care

Caring for biennial evening primrose consists of simple manipulations. Watering as needed, as the soil dries up. In drought, the number of watering should be increased, but in general, the plant will tolerate a short drought without problems. More attention should be paid to the condition of the soil, it must be systematically loosened, avoiding compaction. It is also important to remove weeds.

In the first year, one top dressing is enough at planting, in the second year - in early spring and during the formation of flowers. You can use a complex mineral fertilizer in liquid form. In order for the bushes to please with a beautiful flowering for a long time, it is necessary to regularly remove the faded flowers. By the way, it is best to immediately limit the flower bed or flower garden where the biennial evening primrose grows with sheets of metal or other enclosing material that will not allow the growth of the root system, because it gives a lot of growth.
