THE FLORAL WORLD AND GARDEN GUIDE. 
few observations on the several classes of yellow roses, and the 
cultivation they severally require. 
Macartn£V. — In the Macartney section there are several 
varieties that show more or less of the coveted colour. Alba odorata 
has white flowers, which are yellowish in the centre. Hardy's Rose, 
the result of a cross between R. involucrata and R. berberidifolia, 
has flowers of a pale yellow, spotted with purple at the base. Rosa 
Hardi was raised by M. Hardy, of the Jardin de Luxembourg;, in 
the year 1836. In all its characteristics it is very distinct, aud v\e 
quite agree with Mr. William Paul, who in his most useful and 
original work, “ The Rose Garden,” says : “ We think it distinct 
enough to stand alone.” Alas ! Hardy’s Rose has no constitution, 
and on the cold clay soil of Stoke Rewington, all it does after being 
carefully planted is to dwindle away. But we have done well with 
it planted in a peat border, in a sunny lean-to house in a very damp 
position, and attribute our success to the free ventilation atforded 
during summer, and the very small amount of artificial heat em- 
ployed in winter to keep frost out. The amateur intending to breed 
from this plant would do well to plant it in peat in a brick pit, as it 
would then be completely under command, and as nearly as possible 
in the condition of a rose in the open ground, but enjoying perfect 
shelter. As a matter of policy, however, we should advise the 
amateur to go anywhere for pollen rather than to Hardy’s 
Rose. 
Scotch. — In this section occur several yellow roses, and they 
all produce seed abundantly, aud being hardy, ofl'er desirable 
qualities to the hybridizer. As seed-bearing parents, however, they 
are perhaps less valuable than as supplying pollen, because of the 
short-lived character of their flowers, and the brevity of their season 
of bloom. The growth is dwarf, excessively spiny, and they multiply 
rapidly by suckers, v hich rise up some distance from the parent 
plant. Tlie flowers are always more or less double, very small, 
globular like litt‘e balls, and agreeably fragrant. The varieties are 
only to be met with in old gardens, as they are all quite out of fashion. 
We should select, with a view to possible uses in hybridizing, the 
following : — Josephus, a good plant, with light yellow flowers ; 3Iary 
Sfuarf, lemon yellow ; 3Irs. Hay, tawny straw colour ; True Yellow, 
pale yellow in bud, creamy white when expended. They should all 
be grown as bushes, for they make miserable standards. Any soil 
will suit them, but they require a pure air. A hedge of True Yellow 
would make a pretty feature in some out-of-the-way spot, but would 
not be good enough for the rosarium proper. They are strictly 
summer roses. 
ScLPiiUREA is a relation of the Scotch rose. It has pale green 
glaucous leaves, erect shoots, which are covered with Jong prickles. 
The Double Yellow has flowers of large size, very double, aud a lovely 
yellow colour. It is, unfortunately, without odour. It m an old, very 
old rose, with an incorrigible habit of bursting just when it should 
open beautifully. Parkinson, writing in 1629, says: it is “so 
thicke and double, that very often it breaketh out on one side or 
another, aud but few of them abiding wb-ole and faii-ein our country.
