A rose is a bush plant of the genus Rosa and the flower of this plant produced. Wild roses of over 100 species, mostly grown in the Northern Hemisphere cool tube. Species roses are generally thorny bushes or climbing plants that can reach high 2 to 5 meters. Although rare, high-climbing roses in the other plants can reach 20 meters. Most species have leaves that between 5-15 cm in length, two-two opposite (pinnate). Compound leaf petiole each consisting of at least 3 or 5 to 9 or 13 children leaves and leaf penumpu (stipula) oval, pertulangan pinnate, the beringgit edge, tapering to the tip of the leaves and thorns on the stems close to the ground. Roses actually not a tropical plant, most species knocked all the leaves and only a few species were in Southeast Asia, the evergreen throughout the year.

Flowers consist of 5 crown leaves with the exception of Rosa sericea which only has 4 leaf crown. Flower color is usually white and pink or yellow and red in some species. Ovaries were at the bottom of the crown leaves and leaf sheath. Flowers produce aggregate fruit (grown from a single flower with many pistils), called rose hips. Each pistil develops into a single fruit (achene), while the collection of single-wrapped fruit pulp on the outside. Species with flowers that open wide to invite the arrival of more bees or other insects that help pollinate so tend to produce more fruit. Glorification of roses produce flowers that leaf crown closed, making it hard pollination. Some fruits are red roses with a few exceptions such as Rosa pimpinellifolia that produce fruits dark purple to black. In some species such as Rosa canina and Rosa rugosa rose hips to produce fruit that is rich in vitamin C and even among the natural sources of vitamin C the most wealthy. Rose hips fruit-eating birds like the fruit that helped spread the seeds of roses with dirt removed. Several species of birds such as finches also eat the seeds of roses. In general, roses have thorns shaped like a hook that serves as a grip when climbing other plants. Some species that grows wild in sandy soil in coastal areas such as Rosa rugosa and Rosa pimpinellifolia adapt to a straight razor like a needle that may serve to reduce the damage caused by animals eating, holding sand in the wind and protect the roots from erosion. Although already protected by thorns, deer do not seem afraid and often damage the roses. Some species of roses have thorns that are not developed and not sharp. Roses can be plagued with several diseases such as leaf rust which is the most serious diseases. The reason is Phragmidium mucronatum fungus that causes leaf loss. The disease is not so dangerous as Wheat mildew fungus Sphaerotheca pannosa caused, while the disease black spots marked the emergence of black spots on leaves caused by fungi Diplocarpon rosae. Roses also a food for the larvae of some Lepidoptera species.
