Dierville: all about landing and care

Dierville is a member of the honeysuckle family. The Latin name of this plant - Dierville - comes from the name of a French surgeon named Maren Dierville. It was he who first brought this shrub to France from Canada.

Dierville are deciduous shrubs that differ in bright green leaves located opposite. The calyx of the plant is 5-membered, which is retained on the fruits, there is also a tubular, narrow, two-lipped nimbus. Sometimes this type of plant is referred to as Weigel, since they have similar features. These bushes are very beautiful and look very elegant in the summer, and their dense shiny foliage is especially appreciated. In the fall, it becomes bright yellow or with a reddish tint. Dierville are often used in landscaping to organize hedges, as well as to create decorative groups located near ponds. Very good species for breeding in gardens are those that are frost-resistant in central Russia.

Types of Dirvilla

One of the North American species, the Diervilla sesselliferous, grows in the mountain forests of the eastern part of the mainland. This is a shrub with dense branches 1.5-1.8 meters high. The bush has elongated and ovoid-shaped leaves, in which there is a jagged edge and a fairly strongly elongated peak. In July and August, umbellate inflorescences appear on the tips of the shoots, which consist of small, closely spaced yellow flowers of 3-7 pieces. In the autumn, the fruit-boxes ripen. In warm weather, two valves open out of the box, from which small seeds spill out. Fruiting of the bush occurs from the age of three.

In the culture of North America, this species has been known since 1844. We have grown since the 19th century in botanical gardens.

The second known species - cirqueus dirville is also a North American species, where it grows in mountain forests. The shrub reaches 1.5-2 meters, has rounded shoots, which are covered with hairs in cross section. But unlike the sedentary dirvilla, it has more rounded shoots. Lemon yellow flowers gather panicled multi-flowered inflorescences. It has been cultivated since 1898, and is often used as a groundcover for fixing coasts and slopes.

Honeysuckle dierville also came to us from North America, where it lives on rocky slopes and along river banks. This is a low shrub with a height of 1-1.8 meters. The leaves are long (4-10 cm), oblong-oval in shape. The flowers are yellow, collected in inflorescences of 2-3 flowers. It has been known in culture since 1700, and was the first species to become famous.

A hybrid species is the shiny Dierville. It is winter-hardy, loves moisture and has been known since 1850.

How to plant and care for a plant

Dierville love moisture, and therefore in natural conditions often live along the banks of streams and rivers. They are quite unpretentious to growing conditions, well take root and grow on any soil. Therefore, when planting, it is advised to choose medium-moist areas with little dimming. Good conditions for growing plants in culture are created using the canopy of rare trees.

The most ideal time for planting shrubs will be spring, at a time when the soil has already warmed up, but most plants have not yet opened their buds. The landing pit should be 40-50 cm deep, 40 cm in diameter. After the pit, it is filled with humus and sand. Before planting, the roots of the seedling and its broken branches are pruned by pruning shears. After planting in the ground, seedlings must be watered.

To protect the root system, it is necessary to retain moisture in the soil, which is achieved by mulching. It must be done in the spring, when the soil is still quite moist. Mulch from peat, bark and wood chips crumbles evenly around the shrub. The contour of the coating corresponds to the projection of the crown of the shrub, or slightly exceeds it (15 cm).

For the plant, sanitary pruning, also performed in the spring, may come in handy over time. Sometimes in harsh winters, the bushes freeze to snow, but such damage is still restored and even bloom.

How to propagate a dirville

Diervilla reproduces with the help of offspring, seeds, cuttings and layering. The simplest way is to transplant root offspring that form on the shrub every year. Evening specimens in the spring must be carefully excavated, and then transplanted to a new site. Horizontal layering is easily obtained if already at the beginning of the season long shoots are dug into the substrate. Next spring they are separated by secateurs and transplanted. Green cuttings of dirvilla root very easily, the percentage of survival is 90-100 percent.

When planting seeds, they must be sown in fertile and light soil. To accelerate their growth, stratification in sphagnum or wet sand can be carried out.
