[L. rosa.] A shrub, usually with prickly stems, and large, beautiful, and sweetly-smelling flowers. The varieties of roses are generally classed as damasks, banksia, noisette, perpetuals, French, Chinese, Scotch, celestial, and moss roses. All may be propagated by layers, some by budding or grafting, and many by separating the roots. The moss rose came from Holland, the cabbage rose from Caucasus, and the yellow rose from Persia. In France the cultivation of the rose is a science. The varieties are great; of the tea rose alone there are 122 kinds. The Cherokee rose is a native of China, which has run wild in the American States. The sweet brier has also escaped from cultivation, and is found in the hedgerows. The oldest rose-bush in the world is at Heldersheim, in Germany. The trunk is as large as a man's body ; and in the year 1079 a framework was put up to support its branches. It is supposed to be over 1,000 years old. - Otto of roses is an oil distilled from petals or leaves of damask or musk roses. The best otto of roses is made from Cashmere roses in India.
