Canadian roses: the best frost-resistant varieties, description, cultivation and care

Description

The variety was bred in the famous German kennel Kordes. It differs in flowers with double dense and dense petals, the diameter of the buds is up to 11 cm, the color is bright red with a yellow middle

The height of the bush can reach two meters, there are even taller specimens, therefore, when growing this variety, it is important to periodically carry out the pruning procedure

The stems are quite thick, strong, but plastic at the same time. Among the advantages of the culture, it is worth noting resistance to the most common diseases, for example, powdery mildew. In the sun, the buds do not fade, and after the rain, there are no stains on the petals. The foliage is quite dense. Flowering is very abundant and repeats several times until September. The shrub can be used as an element of garden decoration, and can be used to decorate the facades of buildings. Dense foliage and bright saturated flowers will hide all flaws on the wall of the building. You can also hide a dry tree or an old post on the site under the roses.

The disadvantages include the exactingness of the soil and the subtle aroma of flowers. The buds are very pleasantly fragrant, there is a combination of floral and fruity notes in the smell, but still it cannot be said that the aroma spreads to the entire district. It is a very light and delicate scent.

Description of the variety

The climbing rose "Lavinia" has thin and long highly branching shoots, and the bush itself can grow up to three meters in height and up to one and a half meters in width. On the flowering shoots, clusters of inflorescences are located, in which from three to seven roses are collected. When the buds open, the flowers are in the shape of a bowl, the petals are gathered around the corolla and have a rich pink hue.

The leaves of the rose are alternate, five leaf blades are attached to one petiole, four are arranged in pairs, the fifth at the top. They are dark green in color and have slightly jagged edges. The encyclopedic description of the "Lavinia" variety indicates that the leaves of the bush are large and very dense. They are attached to the branches with the help of special leaf internodes.

The roots of this climbing rose are highly developed, they need a lot of space for successful growth. Usually they go deep into the soil at a distance of up to two meters. The roots of roses do not like stagnant moisture, therefore, when choosing a planting site, you need to ensure that the groundwater does not come closer than two meters to the surface of the earth.

Climbing roses often need certain props to relieve stress on their long stems covered with flower caps. Rose "Lavinia" is famous for the fact that it can successfully grow and develop without support. Its branches are very strong, thick and flexible, they are rather difficult to break, but they are malleable when creating curved structures.

The variety is also known for the fact that not only the bush itself, but even its delicate fragrant flowers are quite resistant to the effects of prolonged rains.

Decorative qualities, growing conditions, advantages and disadvantages of the variety

The climbing rose "Lavinia" (Lawinia, Tantau, Germany, 1980) is considered one of the best varieties among professionals and amateur gardeners. And rightfully so. During flowering, the bushes are covered with pink flowers so densely that leaves are not visible behind them. The buds open alternately from the moment of flowering until late autumn. At the same time, a strong floral-sweet aroma spreads.

Brief description of the variety:

Autumn - early, mid-October.

Note:

★ - minimum, ★★★ - maximum.

Climbing rose - sort "Lavinia" (Lawinia).

• In the international register, the variety is listed as a climber. Numerous experiments of gardeners have proved that it can be grown as a scrub without support, thanks to its dense and powerful shoots.
• With abundant flowering, the shoots bend picturesquely under the weight of the buds.
• Easily guided and secured to any form of support.
• They are highly resistant to the main diseases of roses.
• They negatively tolerate excessive waterlogging; with prolonged rains, the flowers bloom poorly or do not open at all.
• Under conditions 5 and 6, zones hibernate without shelter, subject to a mild winter and the absence of unusual frosts.

Advantages (pros) Polyantha-Rose

• the habit (appearance) is rather compact,
• these are low deciduous shrubs;

• leaves are glossy;
• predominantly double flowers of pink and red color are collected in racemose inflorescences; they are not large, but there are many of them;
• with appropriate care (regular watering, top dressing), the flowering is luxurious, long-lasting: the first flowers bloom at the beginning of the summer season, and the last ones - at the end of autumn (the southern coast of Crimea and the Black Sea coast of the Krasnodar Territory);
• they winter well, but after planting for the first 1-3 years, you need to insure yourself and cover them with spruce branches or build an air-dry shelter on arcs;
• They are not afraid of traditional pink diseases, the causative agents of which are Sphaerotheca pannosa Lev. var. rosae Voron and Marssonina rosae (Lib.), but when it is cool and damp in summer, they cannot resist mushrooms;
• they are practically not cut off, especially if they are used as ground cover shrubs; slightly trimmed on the sides in the borders; shorten the shoots knocking out of the desired contour with the standard culture. Plus sanitary pruning, which is mandatory for roses;
• perfectly cut by green (June-July) and lignified (autumn) cuttings (own-rooted);
• used in various elements of the design of the suburban area;
• stand in cut for a long time (within 2 weeks) without losing color.

Landing

It is recommended to plant the plant in the fall, a month before freezing temperatures or in the spring after the soil warms up to +10 degrees. The Florentina variety is quite capricious in choosing a site, and therefore you need to prepare a suitable place in advance. The lawn should be well lit and ventilated, however, drafts must be excluded. Groundwater is permissible at a depth of at least one meter. It is better to choose a small slope for planting. If you plant a rose in the lowlands where water accumulates, then this will provoke the onset of diseases.

As a soil, preference should be given to loam or black soil. The composition of the soil should be slightly acidic.

As soon as the desired area is selected, and the soil is prepared, you can proceed directly to planting. Before this, it is recommended to soak the seedlings in water for several hours.This manipulation will allow the shoot to adapt more quickly to new conditions. You can hold the sprout in the root growth stimulant solution for 3-4 hours. Next, follow these steps:

• dig a hole 60 cm deep;

• place pebbles or gravel at the bottom with a layer of 10 cm, they will perform a drainage function;

• pour fertilizer into the pit - it is usually recommended to use compost or rotted manure;

• plant a bush so that the root collar is three centimeters below the ground;

• compact the soil around the seedling and water it well;

• mulch the soil, peat is suitable as mulch.

Care

The cultivation of the presented variety is not particularly difficult, but some rules must be followed.

• The soil should be loosened regularly so that the roots are provided with a drainage system and grow well.

• Weeds need to be eradicated. Burning fallen leaves and branches can be an additional preventive measure against disease.

• Watering is carried out twice a week, while the water should be warm and settled. In drought, the frequency of watering should be increased. At least a bucket of water is poured out at a time.

• It is required to mulch the soil.

• In the spring, it is recommended to feed the shrub with nitrogen-containing mixtures; in the summer it should be fertilizers that contain phosphorus and potassium.

• For the winter, the plant takes cover. A dense polyethylene film, spunbond or spruce branches are suitable as a covering material. The branches must be removed from the support and laid horizontally, but in such a way that the stems do not touch the ground.

• In the spring, when the buds begin to swell, pruning is carried out. If you want abundant flowering, then the branches are cut in such a way that 5-7 buds remain on each. If you need to refresh an adult bush, then you can leave 2-3 buds. In the summertime, faded buds and dried stems are cut. Autumn pruning before wintering is carried out in the same way.

• It is recommended not to allow flowering in the first year of planting, since in the following years the plant may produce a small number of small buds.

• To avoid the attack of pests next to the rose, agronomists advise planting calendula, lavender or marigolds: most insects are afraid of their smell and therefore will bypass the bush. The rose itself gets along well with such "neighbors".
