The rose is one of the most widespread and well-known ornamental plants. The use of roses is huge and varied. In open field and greenhouse cultivation, roses are grown as cut flowers. Cut roses are widely used in flower arrangements and interior decoration. In cities and parks, roses are planted in flowerbeds, greenery and flower beds, constituting a colorful decoration throughout the summer. In home gardens and allotments, they also decorate the surroundings and provide cut flowers throughout the summer. Varieties with long, slender shoots are used as climbers for planting gates, pergola, retaining walls, balcony walls, railings etc.. Many are dropped off in parks, botanical species that are completely frost-tolerant as ornamental shrubs. In some countries, roses are the basic raw material for the production of rose oil.
Today's noble roses are multiple hybrids of many noble roses and wild species. Ornamental gardening has several thousand varieties of roses. Many of the old varieties are replaced by new ones, better varieties, characterized by more valuable features.
In gardening practice, the division of roses into 4 great groups: a) large-flowered roses, b) multi-flower roses, c) sticky roses, d) park roses.
Large-flowered roses. They are characterized by a nice shape of the bud and large flowers of various colors and shades.
In our climatic conditions, they require protection against frost. The most numerous breed of roses in this group are the so-called. tea hybrids. Sometimes Pernet roses and renovators are still in cultivation.
Multi-flower roses. They have long flowering and are quite resistant to frost, but they require protection for the winter in our conditions. We distinguish the following groups of multi-flower roses:
1. The right polyantes (Rosa polyantha) - with small flowers gathered in corymbals.
2. Poliant hybrids - with large flowers, but rare inflorescences.
3. Bouquet hybrids (R. floribunda) - with large, full flowers in rare inflorescences.
4. Multi-flower bouquet hybrids (R. floribunda grandiflora) - with very large flowers, placed several at the top of the shoot. The size of flowers is sometimes the same as in large-flowered varieties.
Multi-flower roses are primarily suitable for planting beds and flower beds, dc growing in pots.
Some of these, and in particular of the class Floribunda grandiflora, they are suitable for growing in a greenhouse.
Adhesive roses. They have flabby shoots going down to 5 meters in length. Apart from varieties that bloom once a year, but very abundantly for a period of 2-3 weeks, there are recurring flowering varieties in this group. However, they are characterized by weaker and less effective flowering. Some varieties of sticky roses do not require winter casing.
Park roses. They come from wild species. They are completely resistant to frost. They are used as ornamental shrubs in parks.
