Roses are shrubs of the genus Rosa as well as the name of this plant produced flowers. Wild roses of more than 100 species mostly grown in the northern hemisphere the valve cool. Species roses are generally a thorny shrub or climbing plant whose height can reach 2 to 5 meters. Although rare, a climbing rose plant height in other plants can reach 20 meters.
Most species have leaves that are between 5-15 cm in length, two-two opposite (pinnate). Leaf petiole of each compound that consists of at least 3 or 5 to 9 or 13 children of leaves and leaf fulcrum (stipula) oval-shaped, pertulangan pinnate, edges beringgit edge, tapering at the tip of the leaves and thorns on the stem close to the ground. Rose was not really tropical plants, most species shed all their leaves and only a few species that exist in Southeast Asia are evergreen throughout the year.

Fruit of roses (rose hips) of Rosa canina
Flowers produce aggregate fruit (grown from a single flower with many pistils), called rose hips. Each pistil develops into a single fruit (achene), while a collection of single-wrapped fruit pulp on the outside. Species with a wide-open flowers more inviting arrival of bees or other insects that help pollinate so tend to produce more fruit. Results of breeding roses produce flowers that leaf crown seal, making it hard pollination. Some fruit red roses with a few exceptions such as Rosa pimpinellifolia that produce fruit dark purple to black.
In some species such as Rosa canina and Rosa rugosa rose hips fruit is very rich in vitamin C even among the natural sources of vitamin C the most wealthy. Rose hips fruit-eating birds like the fruit that helps spread the seeds of roses along the dirt is removed. Some birds such as Finches also eat bird seeds roses.
In general, roses have thorns shaped like a hook that serves as a handle while the other climbing plants. Some species that grows wild in sandy soil in coastal areas such as Rosa rugosa and Rosa pimpinellifolia adapt straight needle-like thorns that may serve to reduce the damage caused by eating animals, hold wind blown sand and protect the roots from erosion. Although already protected thorn, deer do not seem afraid and often damage the roses. Some species roses have thorns that are not growing and not sharp.
Roses can be plagued with several diseases such as leaf rust, which is the most serious diseases. The cause is a fungus that causes hair loss Phragmidium mucronatum leaves. The disease is not as dangerous as Wheat mildew caused by the fungus Sphaerotheca pannosa, while the disease Black spots marked the onset of dark patches on the leaves caused by fungi Diplocarpon Rosae. Rose is also a food for the larvae of some Lepidoptera species.
Roses thrive in temperate climates, although some cultivars are the result of joining methods (grafting) can be grown in subtropical regions to temperate regions tropis.Selain as cut flowers, roses have many benefits, including antidepressant, antiviral, antibacterial, anti-inflammatory, and source of vitamin C. Rose oil is one of the essential oil distillation and evaporation of the leaves so that the crown can be made into perfume. Roses can also be used for tea, jelly, and jam.
