RÒSA, Linn. From the Celtic rhod, red ; m
reference to the prevailing colour of the
ñowers. Linn. 12, Or. 3, Nat. Or. Rosàcem.
The name of this genus carries with it a charm
as well for the beauty as the nnrivalled fragrance
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
R O S
resort to the latest and best catalogue of Eoses
now actually iu cultivation ; such as that of
Messrs. Elvers and "Son, of Sawbridgeworth,
Hertfordshire, which is not only the best as a
catalogue, but as containing otlier 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 climbing
kinds, by cuttings of the young wood
placed in a gentle heat. The Moss, and Provence
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 common
dog-rose, is the best for budding upon ; it
is asserted by some cultivators, that all roses
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 throughout
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. canina is astringent,
and employed in medicine in cases of
chronic diarrhoea and other maladies. The
various preparations from the flowers are rosewater,
vinegar of roses, attar, or essence of
roses, &c. Synonymes: 1, -K. h'^hrida; 2, R.
