ather, particularly on light soil, the plants need to be
well watered, but in retentive ground thorough drainage must be insured.
Should signs of debility appear, transplant to rich soil, where they
will soon regain vigour.

A popular half-hardy Campanula is =C. fragilis=, of trailing habit. The
starry pale blue flowers are seen to most advantage in hanging-baskets.
The charm of these flowers is wholly lost if they are placed on a stage
in the greenhouse; and they are not entirely satisfactory in a window
where the light is transmitted through the petals, as this robs them of
colour and substance. But hanging in a conservatory with plenty of air
and space their slender drooping stems are very graceful, and the light
reflected from the flowers does full justice to their beauty. Sow in
pans during February or March and pot on as required.

All the foregoing are perennials, but two little hardy annual Campanulas
are =Attica= and =A. alba=, growing about six inches high. They make
useful foreground plants, and are quite at home in rock gardens. Sow in
April on light soil.

==The Canterbury Bell== has already been alluded to; it is a charming
hardy biennial forming a valuable feature of the mixed border. The large
semi-double blooms of the Cup and Saucer class and the double varieties
are modern introductions which have become extremely popular; the range
of colours now includes the most delicate shades of pink, mauve, and
blue, in addition to pure white. Seed may be sown from April to July.
When the seedlings are large enough transplant them where required for
flowering in the summer of the succeeding year. But Canterbury Bells are
also interesting in the greenhouse during spring; for this work pot them
in October and on to December. So treated, they bloom even more
generously than in the garden. There can be no more beautiful adornment
for a hall or large drawing-room than a well-placed group of the fine
white flowers, backed by a mass of dark-foliaged plants.

==CANNA==

==Indian Shot. Half-hardy perennial==

Cannas have ceased to be regarded simply as sub-tropical foliage plants,
adapted only for the adornment of beds and borders. They have not lost
their merits for this purpose, although in all probability the taller
forms will be less grown than formerly, because the new dwarf varieties,
which maintain a high standard of beauty in the foliage, include a
diversity of rich tints previously unknown, and they posse
