the middle of July until October. Forming a fine late summer and autumn bed for back- 
ground effect, if encouraged in its upright growth, and equally adapted for a front group, 
if the first stages of growth are neatly secured to the ground by hooks, observing in this, 
and in most other plants, to place the most vigorous plants towards the centre of each bed. 
HINTS ON THE CULTIVATION OF YELLOW HOSES.

f. 
Living among Hoses, where the presence of nearly two thousand varieties forms a great 
source of attraction, it is my good fortune to enjoy the privilege of interchange of thought with 
many of the principal connoisseurs of this flower. To such, of course, I do not address these 
observations. But there are others, whose love of roses exceeds their knowledge of the art 
of culture, and by such, how often are the questions raised, “ Have you any Yellow Roses ? ” 
“ Are they not very difficult of culture ? ” The answer to these questions will be the 
subject of the present paper. 
To the first question, we reply, “ There are Yellow Poses, but their number is few.” 
To the second, we can faithfully say, “ They are not difficult of culture, but they require a 
treatment somewhat different from that bestowed on Roses in general.” 
It has been customary to class as Yellow Roses, kinds that are not purely yellow, such 
as the yellow Banksia3, and varieties of the Noisette, and Tea-scented, in which there are 
traces of this colour intermixed with buff, salmon, sulphur, straw-colour, and even white. 
Into the justice of this classification we need not stop to inquire further than to remark 
that, as the Botanical and Horticultural Societies of London have rejected it, there are 
grounds for anticipating a fresh arrangement. But till such occur, we must stand upon 
the old ground, and will proceed at once with our remarks on culture. 
Yellow Roses, then, may be considered as of two kinds — 1st. Pure yellows : 2nd. Shaded 
yellows. To the first belong the Persian Yellow, Harrisonii, Yellow-brier, and single 
yellow Austrian Roses; also, the old double yellow, belonging to Rosa Sulphurea of 
Botanists. 
The Persian Yellow was introduced from Persia through the Horticultural Society, in 
1837, and is of undoubted merit. It may, with justice, be called the King of the Yellows ; 
the colour is pure and golden, and under proper treatment it is a profuse bloomer. The 
plant, when young, grows vigorously, sometimes making shoots three feet in length in the 
course of one season, but this rate of growth is not sustained from year to year. Pruning 
is an important operation here ; the main shoots should have the mere tips cut off, as the 
flower-buds are produced from the eyes near their summit; consequently, if these are all 
removed, there will be no flowers, the eyes near the base producing wood-shoots only. As 
the eyes are placed at small distances, it is well to remove some after pruning ; often two 
or three may be rubbed out together. The plant seems rather impatient of manure unless 
given in a thoroughly decomposed state. It should be planted in turfy loam, mixed with 
one-eighth each of lime, river-sand, and leaf-mould. It is admirably suited for pot-culture. 
I have six plants, which were potted last Autumn, bearing nearly 500 healthy flower-buds, 
the whole of which I expect to expand. They were treated as follows : — After being potted 
and pruned, the branches were drawn down and fastened to a wire passed beneath the rim 
of the pot, so as to form an umbrella-shaped head. Two-thirds of the yet undeveloped buds 
were rubbed out, leaving four or five near the base to form flowering- wood for the next year. 
One plant that was slightly forced has bloomed beautifully, and the flowers of the others 
which have been shaded are now showing colour. No green-house or parterre should be 
without the Persian Yellow. 
The Harrisonii, or American Yellow, is a garden seedling, introduced from America 
about fifteen years since. This is even a more profuse bloomer than the last, but is paler 
m colour and less double. It thrives in the same soil and requires similar general treat-
