ROSE

The rose is a type of flowering shrub. Its name comes from the Latin word Rosa. The flowers of the rose grow in many different colors, from the well-known red rose or yellow roses and sometimes white or purple roses. Roses belong to the family of plants called Rosaceae. All roses were originally wild and they come from several parts of the world, North America, Europe, northwest Africa and many parts of Asia and Oceania. There are over 100 different species of roses. The wild rose species can be grown in gardens, but most garden roses are cultivars, which have been chosen by people. Over hundreds of years they have been specially bred to produce a wide variety of growing habits and a broad range of colors from dark red to white including as well yellow and a bluish/lilac color. Many roses have a strong, pleasant scent. Most roses have prickles (incorrectly called thorns) on their stems. Rose bushes are able to tolerate a wide variety of growing conditions. The fruit of the rose is called a hip. Some roses have decorative hips. Roses are widely used across the world as symbols of love, sympathy or sorrow.

Anatomy

In general, rose grows in cool air areas. The height of the tree can grow to reach 2 to 5 meters. However, there are also those that can grow to reach 20 meters by propagating to other plants.

If you are curious about the structure of this plant, try to look at the information below.

• Leaf

Rose has compound leaves, in the sense that one stalk consists of several leaves. For modern roses, it usually has five leaves for each stalk ranging in size from 5 to 15 cm. Whereas in garden roses, the number of leaves in each stalk can be more, which can be seven, nine, or more. In the upper leaflet, called the leaflet terminal, it is located attached to the leaf stalk. For other leaflets that have stems called petioles. The base of the leaf which has leaves like wings is known as stipule and the stipule tip is commonly known as the earlobe.

•   Thorns

One of the characteristics of a rose is having a thorn shaped like a hook. These spines actually have different functions from each species. In the types of rose plants that propagate, these spines are useful as hooks or handles when penetrating other plants around it. For modern types developed in greenhouses or flower gardens, these spines function so that no predatory animals enter the greenhouse or flower garden.

•  Crowns and Petals

Crowns of roses consist of several petals, where the number will determine whether the roses are classified as single, semi-double, double, or very double flowers. A single flower only has one row of petals with a number of 5 to 12 petals. For those that include semi-double classifications, the number of petals is 13-25 in two or three lines. Petals with more than 25 in three rows or more belong to the double classification. And those with 45 to 50 petals in many rows belong to a very double classification.

• Stamen and Pistil

This flower will bloom from buds which are initially covered by green leaves such as a sheath known as sepals or leaves that change shape into petals. When the rose is fully bloomed, thin filaments or stamens will be seen in the middle. Stamen is a reproductive part of male flowers. He will release pollen from the end called the sari. As for the female part, the pistil is located in the center of the stamens.
