Rose is a wonderful representative of the flora. There are many varieties of this flower. They vary in color, size and characteristics. The structure of a rose of one variety can be very different from another. This is due to the fact that for hundreds of years gardeners have grown new species by crossing different varieties. The structure of the rose, its varieties and features will be discussed in the article.
Description
In a rose, the structure of a bush can be narrow-pyramidal and sprawling. Its height reaches from 30 to 200 cm. Roses are distinguished by two types of perennial branches - these are uterine, they are also the main ones, and branches with complete growth. The length of the peduncle of a garden rose is from 10 to 80 cm.
Rose flowers amaze with their variety and quantity. Their sizes range from 1.7 cm to 18.5 cm, and the number on the bush is from 5 to 128. The structure of the rose, the shape of the flower, the smell and color are also varied. So, for example, a rose variety has recently been bred that has a greenshade. To date, there are more than 30 thousand varieties of roses.
Classification
Roses are divided into three main groups:
- varietal;
- garden (ground cover and flower beds);
- wild and their hybrids.
It is worth noting that this is not a universal classification, and there are various variations of it. Among the types of roses that are used in landscaping, there is a division into climbing, varietal and deciduous varieties. Climbing and park varieties are often referred to wild and their hybrids. The most common are deciduous and shrubby groups. They differ in the duration of flowering and high growth rate.
Root system
The root system of a rose bush is pivotal. In the case of vegetative reproduction - fibrous. The skeleton is the largest of all the roots of the system, about 3 cm in diameter. The root collar connects the underground part of the rose with the aboveground one. As for the structure of the rose in terms of its root system, it is also diverse. In particular, the neck can reach sizes from 3 to 15 cm. This depends on the planting depth. The root neck is a very important part of the plant, and when planting, it is imperative to take into account its location in the seedling.
Lobes are small adventitious roots that are located at the ends of the lateral. With their help, the bushes receive all the nutrients necessary for development and growth, as well as water.
Structure of a rose leaf
They are attached to the stem with special knots. In the same way the leaves are connectedwith side shoots. The standard one has from 5 to 7 leaflets that are attached to one petiole. Sometimes their number reaches 15 pieces. Each type of rose has different leaves. They differ in size, shape, texture and color.
Almost all types of adult roses have green leaves - from light to dark. However, there are varieties with a bronze or purple color that give a copper tint. The sheet plate reflects light in different ways. For example, in some varieties, they shine so much that it looks like they are rubbed with oil. Other varieties have an almost matte finish. There are also intermediate options. Thus, they are divided into:
- matte;
- leathery;
- semi-matt;
- glossy;
- semi-gloss.
Sheet plate - smooth or with pronounced convex veins. Usually its size in wild types of roses is smaller than in cultivated ones. The leaf margins are divided into serrated and entire. The matte texture is most often inherent in wild varieties, and the glossy texture is characteristic of cultivated ones.
Structure of rose fruits
Some varieties of roses, at the end of flowering, open the petals and expose the fruits. It mostly happens in the wild. In fact, rose fruits are seed pods. They crown both leaf growths and the places where the sepals were located.
Rose fruits have a bright color, however, depending on the variety, they differ in color, shade, size, and shape. The color is usually bright red. But there are varieties in which hevaries from pale yellow to black-brown.
The shape of the rose fruit is most often round or oval. Also found and bottle-shaped. The sizes are different, from 0.5 cm to 2.5 cm. The fruits, in addition to their direct natural purpose, are used by humans in cosmetology and medicine.
Flowers
The structure of rose flowers has a complex structure. They are multi-flowered - from 5 or more on one bush, few-flowered - from 2 to 3, and single-flowered. They can be located at the top or along the entire length of the bush. They also differ in shape:
- conical;
- spherical;
- square;
- pompom;
- boat;
- rosette-shaped.
It should be noted that as the flower opens, its shape changes greatly. The color of the bud is currently simply amazing. A huge number of colors and shades are displayed. Color is divided into several types:
- single color;
- two-color;
- colorful;
- striped;
- mixed;
- dyed (feathery pattern with a white eye at the base).
Petals, depending on the variety and type, also have a different shape, size, color and aroma. Initially, nature created them as such to attract insects for the purpose of pollination. At the same time, new varieties are being developed that have unusual colors, shapes and aromas only to better sell them because of their extravagance. However, the rose always remains a beautiful flower, pleasing to the eye with its beauty.
