glass, but do not let impatience cause you to submit the plants to 
a bigb temperature, for that weakens them. Flowers fertilised in 
February will, in a warm greenhouse, ripen their seed in good 
time for furnishing plants for spring use the year following. 
They will scarcely do for very early plants, though. 
Raising Primula seed is by many gardeners regarded as a secret. 
If it has been so it is one no longer, and we hope everybody will 
be better by knowing it. Let all who practise it make careful 
selection, and take care to begin with the best strain procurable, 
and seize on every improvement.—A Scotchman. 
ROSA RUGOSA. 
For several seasons one of the most noteworthy features in Mr. 
T. Ware’s nursery, Tottenham, has been the fine clumps of the 
handsome Japanese Rose named above, which form such con-

weather and the low temperatures such as have been experienced 
in the last two or three winters, the plants grow vigorously, and 
every summer flower profusely, the flowers being followed by 
handsome clusters of bright red coral-like fruits. Few orna¬

Perfect hardiness, free growth, compact habit, pretty and abun¬ 
dant white or crimson flowers, and bright-coloured fruits con¬ 
stitute an assemblage of attractions which in these utilitarian days 
cannot be long disregarded. Such a plant deserves popularity, 
and this it will undoubtedly obtain, for all who have tried it 
recommend it to their friends most cordially. 
True, this Rosa has one unpleasant character. The thorny 
accompaniments which an old adage teaches us always to expect 
with Roses are unusually abundant in the case of Rosa rugosa, 
the stems being so thickly clothed with spines of various sizes 
that they present quite a formidable appearance. However, this 
interferes but little with the real utility of the plant, as the flowers 
and fruit are seen to the best advantage when growing, and are 
not so well adapted for cutting as some others. The foliage, too, 
is beautiful, of a fine green tint, the leaves neatly pinnate, each 
leaflet being wrinkled or rugose upon the upper surface. 
The species is a native of China and Japan, where it is said to 
be found growing wild in sandy soil, and it has been also culti-
