THE FLORAL WORLD AND GARDEN GUIDE. 235 
should enlarge rather than contract our range of selection of beau- 
tiful trees in the garden. Having abolished the bottle-brushes and the 
hard mop-headed standards, so-called, he would like to see in suitable 
positions standards with good heads on stout stems of such sorts as 
Blairi No. 2, Coupe d’Hébé, Paul Verdier, and the most vigorous 
teas and perpetuals, all of them to be treated on the principle, that 
as pruning the head checks the action of the root and hardens the 
bark of the brier, so the rich beauty of contour proper to orna- 
mental trees could only be secured by encouraging the growth root 
and branch, such pruning as might be required to be most tenderly 
and cautiously performed. There was yet another class of tree roses 
that were admirably adapted for large places, and formed when 
skilfully handled the most sumptuous of lawn trees. These were 
standards of such as the Sempervirens and Ayrshire sections, which 
when weil made might be likened to fountains, and one rule in the 
management of which was, that they should never be pruned at all. 
An amateur rosarian who had once become familiar with roses in 
this form would no longer tolerate the orthodox mop-headed things 
that were called standard roses—at all events, within every-day view 
of his windows—but would send them to the reserve ground to sup- 
ply cut flowers, or plant them in the boundary fences. to light up the 
green line here and there with a noble boss of flowers. 
CANTERBURY BELLS. 
HE varieties of Campanula media, better known, perhaps, 
as the “Canterbury Bells,” form such an exceedingly 
attractive class of plants, that a word or two in reference 
to them may not be out of place. specially useful are 
~ they to those amateurs who have not over much accom- 
modation for the cultivation of bedding plants, because a stock, 
whether large or small, can be raised without the aid of a single foot 
of glass. My object in penning this note is to direct special atten- 
tion to the type known as Campanula media calycanthema. The 
flowers of the varieties comprising this type have a calyx of precisely 
the same colour as the flower itself, and in many cases of a similar 
shape. Indeed, in some instances the calyx bears so close a resem- 
blance to the flower that it has the appearance of one flower being 
inserted in the other. All the flowers on the same plant are alike, 
and those having a calyx of the size and shape here reterred to repre- 
sented the purest strains. In some cases the coloured calyx is 
only one half the length of the flower, and in others it is split into 
four segments, and stands out at right angles to it, and although the 
flowers with these calyces do not represent so high a state of per- 
fection, they are remarkably beautiful, and produce a glorious display 
in the borders. All three forms will, as a rule, be produced by 
plants produced from the same packet of seed. The plants are some- 
what pyramidal, and branch freely, and clumps of three or four pro- 
duce a huge mass of bloom ranging from three to four feet in diameter. 
The colours range from the purest white to deep blue, and comprise 
August.
