Yellow Rose in Pictures



A rose is a perennial flower shrub or vine of the genus Rosa, within the family Rosaceae, that contains over 100 species and comes in a variety of colors. The species form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp prickles. It is a common error to refer to roses having thorns. Thorns are modified branches or stems, whereas these sharp protrusions on a rose are modified epidermal tissues (prickles). Most are native to Asia, with smaller numbers of species native to Europe, North America, and northwest Africa. Natives, cultivars and hybrids are all widely grown for their beauty and fragrance.

The leaves are alternate and pinnately compound, with sharply toothed oval-shaped leaflets. The plant's fleshy edible fruit is called a rose hip. Rose plants range in size from puny, miniature roses, to climbers that can reach 20 meters in height. Species from different parts of the world easily hybridize, which has given rise to the many types of garden roses.



The name originates from Latin rosa, borrowed from Oscan from colonial Greek in southern Italy: rhodon (Aeolic form: wrodon), from Aramaic wurrdā, from Assyrian wurtinnu, from Old Iranian *warda (cf. Armenian vard, Avestan warda, Sogdian ward, Also the Hebrew ורד = vered and the Aramaic ורדא: these preceded the Greek above. Parthian wâr).

The leaves of most species are 5–15 centimetres long, pinnate, with (3–) 5–9 (–13) leaflets and basal stipules; the leaflets usually have a serrated margin, and often a few small prickles on the underside of the stem. The vast majority of roses are deciduous but a few (particularly in Southeast Asia) are evergreen or nearly so.

The flowers of most species roses 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. The ovary is inferior, developing below the petals and sepals.



The rose has always been valued for its beauty and has a long history of symbolism. The ancient Greeks and Romans identified the rose with their goddesses of love referred to as Aphrodite and Venus. In Rome a wild rose would be placed on the door of a room where secret or confidential matters were discussed. The phrase sub rosa, or "under the rose", means to keep a secret — derived from this ancient Roman practice.



Early Christians identified the five petals of the rose with the five wounds of Christ. Despite this interpretation, their leaders were hesitant to adopt it because of its association with Roman excesses and pagan ritual. The red rose was eventually adopted as a symbol of the blood of the Christian martyrs. Roses also later came to be associated with the Virgin Mary.




Rose culture came into its own in Europe in the 1800s with the introduction of perpetual blooming roses from China. There are currently thousands of varieties of roses developed for bloom shape, size, fragrance and even for lack of prickles.
