T h e hardy kinds of Robinia are remarkably handsome
when in flower, and well adapted for ornamenting
the shrubbery. They will grow in any
common soil; and are increased either by layers or
by grafting the rare species upon the common
kinds, chiefly on R, Pseud-acacia, The stove and
greenhouse species should be grown in a mixture of
loam, sand, and peat; and young cuttings wi l l root,
if planted in sand, under a glass. A. Pseudo-acacia,
if properly seasoned, is equally as strong and as

Rösa, Linn, From the Celtic rhod, red; in reference
to the prevailing colour of the flowers. Linn, 12,
Or. 3, Nat . Or. Rosacea. The n ame of thi s genus carries
with it a charm as wel l for the beauty as the
unrivalled fragrance of its flowers, and it has justly
been the theme of writers, from the remotest
a n t i q u i t y , as a favourite and universal object of
c u l t u r e among all civilised nations. The plants
v a r y in size, and the colours are red, whi te, purple,
yellow, s t r iped, or of almost number less shades
and mixtures, f rom single to semi -double and double.
As it would be impossible to give a standard list ot
t h e most improved cultivated kinds, owing to the
number of superior sorts raised annually f rom seed,
and many oi the varieties being annu^l y lost,
going out of repute, or entirely changing their
appearance from t ime and local circumstances; we
would on that account recommend those who wish to
f o rm a selection of these popular plants, to resor t to
t h e latest and best catalogue of Roses now actually
in cul t ivat ion; such as that of Messrs. Rivers and
Son, of Sawbridgeworth, Hertfordshire, which is
not only the best as a catalogue, but as containing
other |)articulars worthy of the cultivator's consideration.
The rose is propagated by ever y method
capable of being applied to ligneous plants; by
C 272 1
ROS ROS
seeds for new varieties, for obtaining sweet-briar,
and for stocks. The Indian, Chinese, and climbing
kinds, by cuttinas 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
w i t h 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;
i t is also resorted to to preserve some of the more
tender kinds which languish upon their own roots.
Rosa canina, or common dog-rose, is the best for
budding upon; it is asserted by some cultivators,
t h a t 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
s p r i n g ; the Chinese, and other tender kinds, for
dccorating 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 mor e than 55 degrees, but it may
be gradually raised to 65 or 70 degrees of Fahrenh
e i t . The fruit of R- canina is astringent, and
employed in medicine in cases of chronic diarrhoea
and other maladies. The various preparat ions from
t h e flowers are rose water, vinegar of roses, attar,
or esscnce of roses, &c. Synonymes : 1. R. hybrida,
