THE GENUS CAMPANULA FROM A GARDENER'S POINT OF VIEW. 35 
eluding the dwarf and indispensable Platycodon Mariesii, that 
the planter has been justified in making a slight botanical devia - 
tion in the Campanula garden. 
There is the pleasing C. Hendersoni, a sort of pigmy pyra- 
midalis, an almost ceaseless bloomer, and one of the best 
Bellworts— a hybrid itself, it somehow seems to be variable. 
How grandly that pair of Hosf ii show up ! — the pure white 
and the deep blue side by side in big patches. This species 
literally produces sheaves of flowers. With the knife, in sickle- 
fashion, you may reap a handful of spikes 15 or 18 inches high, 
which fill a good-sized vase, and you may repeat the operation 
for many days consecutively. 
Now we get a glance of a more homely group — the commonest 
of our native species — the Harebell, or the Bluebell of Scotland. 
How grandly this does in cultivation ! And our interest is the 
more stimulated in connection with this from the fact that it 
has evolved many beautiful forms, more or less recognised now 
under botanical names, such as liniifolia and alba, soldancllce- 
flora, major, and a double-flowered kind. Rliomhoidea and 
Bapuncidus strike us by their profusion of flowers of deep blue. 
Persicifolia covers a large space, for not only do the root-stems 
wander quickly, but it varies greatly. There are five forms at least 
of white varieties — one, known as coroiiata, having a curiously 
puffed and puckered calyx. The type itself is by no means bad, 
but some of the varieties in both white and blue are great 
advances from the gardener's point of view, notably the one 
known by the long name of C. persicifolia alba grandijiora, and 
you may see amongst chance seedlings several shades of blue to 
match this for size and shape of flowers. Nobilis is not so gay- 
looking a subject, but it strikes one by its peculiar arrangement 
of the flowers. Grandis and gemmifera are useful for their 
sheets of colour, and the white variety of the former is very 
telling. 
As you cast your eye still further back, you see the giants of 
the genus, with, in front of them, yet a few more of intermediate 
stature. These comprise americana, with, by its side, the distinct 
and very uncommon bononiensis. We halt a moment whilst 
viewing this — it is so remarkable. It has long slender stems of 
4 feet, arching outwards, and all the flowers for nearly the whole 
length are open at one time. They furnish the stem in a one-
