Florists in the middle and northern Russian latitudes are faced with the problem of growing roses. Ordinary varieties do not withstand harsh winters: the stems are frost-bitten, the roots rot. Ideal for summer houses and parks were varieties of Canadian roses. The great love among them was won by the rose Cuthbert Grant.
Rose Cuthbert Grant - what kind of variety is it?
The climate of Canada differs little from the Russian: the same cold long winters, short cool summers. Canadian breeders have struggled for decades to grow frost-resistant rose varieties. The result is species that can easily tolerate even Siberian winters. These are the most hardy species, they make up a separate subtype.
Cuthbert grant rose
The cultivation of the Cuthbert Grant variety began in the 19th century. from the works of the scientist W. Sanders. He began to cross interspecific varieties of hardy flowers and received hybrids that withstood frost of −30 ° С. These are Explorer roses, which include Cuthbert Grant.
Grade description
This is an outstanding instance of the Explorer series. Description of flowers: cupped, semi-double dark purple with a velvet tint. When opened, yellow stamens are visible.
Thick elastic shoots end with tassels of 3-9 flowers on elegant pedicels. Branches bend under the weight of clusters.
The bush is upright, grows up to 120 cm. The flower size is 10 cm. The leaves are cold gray-green in color, contrast beautifully with the buds. The aroma is persistent, pleasant.
Advantages and disadvantages of the variety
The plant has several advantages:
- winter hardiness. Withstands −40 ° С;
- endurance, unpretentiousness;
- blooms all season with little respite until frost;
- well cuts;
- they don’t shelter for the winter;
- disease resistance;
- not afraid of temperature changes.
Of the shortcomings, a weak aroma is noted.
Use in landscape design
The variety is widely used in landscape design. Best suited for hedges. Original living fences, borders are erected from flowers.
Note! The bush looks picturesque in the center of the flowerbed as a central composition.
Curly varieties are used in arbors, braid arches, the background for undersized shrubs.
Cuthbert Rose is well adjacent to John Cabot and John Davis, since they have the same agricultural technology. In combination with the variety, Alexander Mackenzie creates a multi-tiered rose garden.

Flower growing
The plant is unpretentious, planting will not cause trouble.
Saplings are bought in agricultural stores. Healthy looking plants are chosen. They come with open and closed root systems (in packages with an earthen lump). Saplings with open roots are planted on the same day. Closed roots have nutrition, these seedlings are planted at a convenient time for the grower.
The best time is early spring. Autumn in the northern latitudes is short and cold. Canadian beauty does not have time to take root.
Seat selection
The plant loves a lot of air and sunny space. In partial shade it also takes root well.
Important! Park roses cannot be planted in lowlands. It’s colder, there is a slight movement of air, the roots rot. Also, the flower does not like dead ends and corner zones, since it lacks air.
How to prepare the ground
The soil is prepared in the fall: they dig, remove the roots, stones, add organic and inorganic nitrogen fertilizers, leave them in the snow until planting. Two weeks before the procedure, the ground is fertilized with mullein, ash, superphosphate are introduced.
Landing procedure step by step
Choose planting material with a long stem. Leaves are removed to the last two. Roots cut, remove unhealthy fragments.
Landing step by step:
- Dig a hole with a depth of 70 cm and the same diameter.
- Pour a bucket of water into it.
- Place a seedling, straighten the roots.
- Sprinkle with earth mixed with sand, so as to deepen the root neck by 5-6 cm.
- The earth is poured with a knoll, it will settle during irrigation.
Plant care
Agricultural technology of roses of Canadian selection does not differ from ordinary varieties.

Watering rules and humidity
Cold-resistant varieties do not like dry soil. In dry summers they are abundantly irrigated strictly under the bush. A lot of water is required during spring feeding. The rest of the time, watering is moderate.
Top dressing and soil quality
Without top dressing, the culture quickly depletes the soil. Therefore, in the spring they are fed with nitrogenous fertilizers, in the summer - with phosphorus-potash, but only after the first flowering.
The soil is loosened, weeds are removed. After watering, mulch.
Pruning and transplanting
Cut the plant in the spring after night frosts. Remove damaged shoots, frozen branches, dry leaves. Strongly thickened bushes thin out.
Important! Transplanted bushes in the fall. Such a plant is sheltered for the winter. Having damaged roots, it will not tolerate frost.
Features of wintering a flower
Cuthbert Grant (or, as she is also called, the rose Cuthbert Grand) tolerates winter well. Before the cold weather, the ground under the bush is mulched with compost soil, they throw more snow.
In rare cases, a rose is sheltered. In this case, it begins to bloom earlier.
Flowering roses
A re-flowering plant does not need special care.
Period of activity and rest
The variety first blooms in the flower beds. After rest, a second, more beautiful flowering begins. Flowers become even darker and more expressive. Repeated flowering reveals all the splendor of a rose.
Further, until the colds, flowering and rest alternate.
Care during flowering and after
All procedures are as follows:
- during the rest period they feed phosphorus-potash fertilizers;
- weed, remove weeds;
- watered as necessary;
- fight pests and diseases.

What to do if it does not bloom
If the rose does not bloom, then:
- not enough sun;
- planted in a draft;
- Incorrect pruning
- a flower grower does not remove wilted flowers;
- shoots without buds did not cut in half;
- did not top dress;
- incorrect irrigation mode;
- pests attacked the bush.
Flower propagation
The flower is propagated by the usual gardener methods: cuttings, layering, dividing the bush, root offspring.
Important! They breed in spring. If a plant is transplanted during the winter, it will not have time to take root, and the roots will freeze. This recommendation applies to northern areas. In the south, ornamental crops propagate in the fall.
Canadian rose Cuthbert Grant propagated in traditional ways.
- Cuttings. In autumn, cuttings are cut from the stems. For food, peat, put in the refrigerator. Closer to spring, the cuttings are obliquely cut, put in a jar of water, periodically changing it. In the spring, when the roots appear, they are planted in the ground.
- Layering. Furrows are made near the bush. Stems are laid in them, fixed, buried. Above the ground, two kidneys are left. The stem is not cut off from the mother bush. He takes root. The layering is left to winter. In spring, cut from the main bush, dig, transplant.
- By dividing the bush. The procedure is carried out before budding. They dig a bush, divide it so that each part is with roots and a stem. The roots are sprinkled with charcoal, dipped in diluted clay, planted.
- Root offspring. They appear themselves in the form of young shoots. Take one year olds. Dig up, cut off the root, which connects the offspring with the mother bush, transplanted.
Important! Transplanted offspring growing a meter from the mother bush, so as not to injure him.
Diseases and Pests
Pathogens are pathogenic fungi. In addition, the plant is affected by viruses and bacteria. Fight with the corresponding pesticides. In time, cut the affected branches.
Note! The cause of the disease can be excessive feeding.
For the prevention of diseases under the bushes in May put a tablet of glyocladine.
Canadian rose is a winter-hardy plant, not whimsical to care for. The bush is very beautiful, widely applicable in landscape design. The variety described above is easily propagated in many ways. Care requires a simple: pruning, watering, feeding.
