The leaves are borne alternately on the stem. In most species they are 5 to 15 centimetres 2. Most roses are deciduous but a few particularly from Southeast Asia are evergreen or nearly so. The flowers of most species have five petals, with the exception of Rosa sericea , which usually has only four. Each petal is divided into two distinct lobes and is usually white or pink, though in a few species yellow or red.
Beneath the petals are five sepals or in the case of some Rosa sericea , four. These may be long enough to be visible when viewed from above and appear as green points alternating with the rounded petals.
There are multiple superior ovaries that develop into achenes. The aggregate fruit of the rose is a berry-like structure called a rose hip. Many of the domestic cultivars do not produce hips, as the flowers are so tightly petalled that they do not provide access for pollination. The hips of most species are red, but a few e. Rosa pimpinellifolia have dark purple to black hips. Each hip comprises an outer fleshy layer, the hypanthium , which contains 5— "seeds" technically dry single-seeded fruits called achenes embedded in a matrix of fine, but stiff, hairs.
Always cut to a live bud pointing away from the center of the shrub to encourage outward growth. A few species of roses have only vestigial prickles that have no points. Traditionally, roses were notoriously challenging to grow. Further information: Rose oil and Rose water. Cultivated roses are often subject to severe damage from insect , arachnid and fungal pests and diseases. Use mulch.
Rose hips of some species, especially the dog rose Rosa canina and rugosa rose Rosa rugosa , are very rich in vitamin C , among the richest sources of any plant. The hips are eaten by fruit-eating birds such as thrushes and waxwings , which then disperse the seeds in their droppings. Some birds, particularly finches , also eat the seeds. The sharp growths along a rose stem, though commonly called "thorns", are technically prickles , outgrowths of the epidermis the outer layer of tissue of the stem , unlike true thorns, which are modified stems.
Rose prickles are typically sickle-shaped hooks, which aid the rose in hanging onto other vegetation when growing over it. Some species such as Rosa rugosa and Rosa pimpinellifolia have densely packed straight prickles, probably an adaptation to reduce browsing by animals, but also possibly an adaptation to trap wind-blown sand and so reduce erosion and protect their roots both of these species grow naturally on coastal sand dunes. Despite the presence of prickles, roses are frequently browsed by deer. A few species of roses have only vestigial prickles that have no points.
Roses are best known as ornamental plants grown for their flowers in the garden and sometimes indoors. They have been also used for commercial perfumery and commercial cut flower crops. Some are used as landscape plants, for hedging and for other utilitarian purposes such as game cover and slope stabilization. The majority of ornamental roses are hybrids that were bred for their flowers.
A few, mostly species roses are grown for attractive or scented foliage such as Rosa glauca and Rosa rubiginosa , ornamental thorns such as Rosa sericea or for their showy fruit such as Rosa moyesii. Ornamental roses have been cultivated for millennia, with the earliest known cultivation known to date from at least BC in Mediterranean countries, Persia , and China.
Most are double-flowered with many or all of the stamens having mutated into additional petals. In the early 19th century the Empress Josephine of France patronized the development of rose breeding at her gardens at Malmaison. As long ago as a collection numbering over one thousand different cultivars, varieties and species was possible when a rosarium was planted by Loddiges nursery for Abney Park Cemetery , an early Victorian garden cemetery and arboretum in England.
Roses are a popular crop for both domestic and commercial cut flowers. Generally they are harvested and cut when in bud, and held in refrigerated conditions until ready for display at their point of sale. In temperate climates, cut roses are often grown in greenhouses , and in warmer countries they may also be grown under cover in order to ensure that the flowers are not damaged by weather and that pest and disease control can be carried out effectively. Significant quantities are grown in some tropical countries, and these are shipped by air to markets across the world.
Some kind of roses are artificially coloured using dyed water, like rainbow roses.
Rose perfumes are made from rose oil also called attar of roses , which is a mixture of volatile essential oils obtained by steam distilling the crushed petals of roses. An associated product is rose water which is used for cooking, cosmetics, medicine and religious practices.
The production technique originated in Persia and then spread through Arabia and India , and more recently into eastern Europe.
