The brightest representative of tea-hybrid roses of scarlet color is the Osiriya variety. Fragrant two-tone buds are a real gem of any bouquet and sophisticated garden decoration.
Description of the rose Osiria (Osiria): what kind of variety
The hybrid tea rose Osiria was bred in Germany in 1978 in the Reimer Kordes nursery. Only the fact that it was used, among other varieties of Snowfire, is reliably known about the gene pool chosen by the originator for work.
For your information! The name Osiria is given to the new hybrid in honor of the legendary country of Assyria that disappeared into the deeps of the sea, like Atlantis.
Rose Osiria
The height of an adult well-formed bush is 70-90 cm. The shoots are long, straight, strong, only sometimes slightly curved. The width of the crown is about 80 cm. The bush forms a sprawling, upward, densely leafy. Leaf large dark green opaque.
The bud is formed in a thick-glass goblet-shaped form, and when fully opened, it turns into a bowl. The petal on the front side is velvety red (ripe cherry or strawberry), and from the inside - cream-milk with silverfish. Flowers are formed at the ends of the shoots always 1 pc. The diameter of the corolla is 9-12 cm. The first bud opens in early June, the last in October. The aroma is spicy, but light, intensifying in wet weather and in the evenings.

Advantages and disadvantages of the variety
Among the indisputable advantages:
- frost resistance up to −23 ° С;
- prolonged (up to 4 months) flowering;
- powerful straight shoots are great for cutting;
- pleasant and distinctive aroma;
- longevity: the bush has been growing for several decades in one place;
- propagation by propagation is easily propagated with preservation of all characters.
Of the disadvantages:
- lack of nutrients can trigger the development of chlorosis;
- on a too hot sun, the bush can get burns, it is better to plant it where part of the day is slightly shaded;
- instability to powdery mildew and rust;
- hard shoots are not suitable for propagation by layering;
- under their own weight, buds that become wet after rain fall.
Use in landscape design
Bushes have a very decorative appearance, therefore, are universally used to decorate flower beds, flower beds, gardens.
Note! Flowers are cut for bouquets, but since they stand in vases for a very long time (up to two weeks), then there are quite enough of them on the bushes.
Flower growing
In the gardens, Osiriya appears mainly from nurseries, where cuttings with an open or closed root system are sold. Sometimes you can find planting material grafted onto a 2-year-old rose hip. Its winter hardiness is 10-15 ° higher.
In what form is landing
A handle with a closed root system can be planted immediately after purchase (end of May, all summer). It is only important to prepare the landing pit in the chosen place. Before planting, a seedling with open roots should be soaked in water for the night.
Closed root seedlings
A quality stem has 2-3 lignified shoots with sleeping buds, well-developed roots. A healthy root is resilient and light without traces of decay.
Important! Spots are a sign of disease, so it is better to refuse such seedlings immediately.
The optimal diameter of the root neck is 8-10 mm. There are no leaves and flowers on the seedlings; maximum buds have blossomed.
What time is the landing
The end of spring - the beginning of summer - the best time for planting. The soil should be warmed to a mark above 12 ° C.
Seat selection
You need to plant in a slightly elevated place where rain or melt water never stagnates. If planted near the walls, then the optimal distance is from 50 cm. A good place is where part of the day (preferably morning) the bright sun shines, and the remaining time reigns light partial shade.
How to prepare the soil and flower for planting
Optimum soil acidity pH = 5.0-6.5. It must be loose and fertile. If soil extracted from the pit is used for planting, then up to 1/4 of sand and peat are introduced into it. Useful additives are wood ash, chalk or dolomite flour. 50 g of superphosphate are mixed from fertilizers (50 g per 1 hole). A seedling with closed roots is not prepared at all, and with open roots it is necessary to pre-soak it in water.
Landing
Step-by-step instruction:
- A pit is dug with a depth of 50-60 cm.
- At the bottom, 5-10 cm of sand is poured with crushed stone or expanded clay for better drainage.
- The bush is deepened by 2-3 cm (but only before the scion).
- They fill it with prepared soil, mulch it, and water it abundantly.
Plant care
All varieties of hybrid tea roses require attention. Osiria is no exception.
Watering rules and humidity
Water the bush when the soil beneath it has dried out (after 2-3 days). Water stagnation is harmful to the roots.
Note! In hot weather, it is useful to have a shower of warm water in the mornings and evenings.
Top dressing and soil quality
Rose responds well to irrigation with mullein, but only in the first half of summer. Mineral fertilizers are bought and made special for roses with a predominance of phosphorus and potassium. In total, up to 4 top dressings are required per season.
Pruning and transplanting
In spring and autumn, sanitary pruning is performed, removing damaged, diseased shoots directed inside the bush. Cut growth below the scion. In spring, the shoots are cut, leaving 3-4 buds on them for a harmonious formation of the crown.
Features of wintering a flower
After autumn pruning (it is carried out after dropping the foliage), the bush is covered with a cardboard box or bag, a film frame. After frost is set at −7 ° C, dry foliage or needles are poured into the shelter. They remove the shelter as soon as a steady positive temperature is established in the afternoon.

Flowering roses
Beautiful flowers are a welcome reward for all your labors. Assyria is a rose that delights them from the very first year after planting.
Period of activity and rest
Flowers are formed only on the shoots of this year. On average, blooming occurs at 2-week intervals, but not synchronously. If several bushes are located nearby, then they can bloom alternately. Flowering lasts from June to October.
Care during and after flowering
Wilted flowers all summer need to be cut. Do it right - until the first bud below the bud. If you cut more, you can loosen the bush. In September, wilted buds are not cut, so as not to provoke an unnecessary growth of shoots.

What to do if it does not bloom
Lack of light, water and nutrients are the main reasons for the lack of buds. Roses bloom even in cold weather, if they have enough phosphorus and potassium. The best strategy is to feed the bush and ensure that watering is done on time.
Note! A transplant is a last resort without a guarantee of success.
Flower propagation
Cuttings are the best method for propagating Osiria roses. The division of the bush is suitable only if the seedling was grown from the cuttings, but not grafted onto the dog rose.
The best time for cutting cuttings is June, when the bush is already in bloom. Shoots need well-formed, strong and long.
Stages of the cuttings procedure:
- The cuttings are cut 10-12 cm long from the end of this year's shoot, removing the bud and leaves from below from it. Leave 1-2 leaves, shortening them by half.
- Having dipped the lower end into the root, the cuttings are buried in a mixture of sand with fertile soil or placed in a container with clean water. From above it is desirable to cover with a cap to maintain optimal humidity.
- The hotbed is placed in the light and kept at a temperature of 22-25 ° C.
- After 3-4 weeks, roots should form.
- Landing in the open ground is carried out after a year or at the end of August.
Diseases, pests and ways to combat them
Before the summer season, the rose is treated with copper sulfate or Bordeaux liquid to protect it from powdery mildew and rust. Then closely monitor extraneous spots on the foliage, and when patients are detected, they are carefully cut and burned.
Note! Anti-aphids are treated preventively, for example, by spraying with a solution of actara or karbofos.
Rosa Osiriya is a real treasure in the garden, because her buds with each subsequent year become only larger and more fragrant. It will not cause much trouble to an experienced gardener, the principles of care are common, as for other tea-hybrid varieties.
