 should be grown in a mixture of loam, peat, 

 and sand ; and cuttings will root freely if 

 planted in sand, under a glass, in heat. See

Rosa, Linn. From the Celtic rhod, red ; in 

 reference to the prevailing colour of the 

 flowers. Linn. 12, Or. 3, Nat. Or. Rosacea. 

 The name of this genus carries with it a charm 

 as well for the beauty as the unrivalled fra- 

 grance of its flowers, and it has justly been the 

 theme of writers, from the remotest antiquity, 

 as a favourite and universal object of culture 

 among all civilised nations. The plants vary 

 in size, and the colours are red, white, purple, 

 yellow, striped, or of almost numberless shades 

 and mixtures, from single to semi-double and 

 double. As it would be impossible to give a 

 standard list of the most improved cultivated 

 kinds, owing to the number of superior sorts 

 raised annually from seed, and many of the 

 varieties being annually lost, going out of 

 repute, or entirely changing their appearance 

 from time and local circumstances ; we would 

 on that account recommend those who wish to 

 form a selection of these popular plants, to 



resort to the latest and best catalogue of Roses 

 now actually in cultivation ; such as that of 

 Messrs. Rivers and Son, of Sawbridgeworth, 

 Hertfordshire, which is not only the best as a 

 catalogue, but as containing other particulars 

 worthy of the cultivator's consideration. The 

 rose is propagated by every method capable of 

 being applied to ligneous plants ; by seeds for 

 new varieties, for obtaining sweet-briar, and 

 for stocks. The Indian, Chinese, and climb- 

 ing kinds, by cuttings of the young wood 

 placed in a gentle heat. The Moss, and Pro- 

 vence or Cabbage rose, by layers or suckers ; 

 also by cuttings of the large fleshy roots, 

 which being planted, and covered with a little 

 light rich earth, will each throw up one or 

 more shoots. This will be found a good and 

 an expeditious mode of obtaining young plants. 

 Budding is chiefly used to produce standard 

 roses, or to increase the number of kinds upon 

 one plant ; it is also resorted to to preserve 

 some of the more tender kinds which languish 

 upon their own roots. Rhsa canina, or com- 

 mon dog-rose, is the best for budding upon ; it 

 is asserted by some cultivators, that all rosea 

 flower finer and last longer, by being budded 

 on this stock. The Moss and Provence kinds 

 are well adapted for forcing in winter and 

 spring ; the Chinese, and other tender kinds, 

 for decorating the greenhouse nearly through- 

 out the year. To keep a succession of flowers 

 of the first-named kinds from Christmas, until 

 their natural season of flowering, a quantity 

 should be introduced into the forcing-house 

 every month from the first of October to the 

 first of March ; the dung heat at first should 

 not be more than 55 degrees, but it may 

 be gradually raised to 65 or 70 degrees of 

 Fahrenheit. The fruit of R. canlna is astrin- 

 gent, and employed in medicine in cases of 

 chronic diarrhoea and other maladies. The 

 various preparations from the flowers are rose- 

 water, vinegar of roses, attar, or essence of 

 roses, &c. Synonymes : 1, R. hfbrida ; 2, R.
