ikes
occasionally measure eight and even ten feet from base to tip. Such
specimens are magnificent ornaments in conservatories and corridors, and
cannot fail to arrest attention at the back of herbaceous borders, or
when used as isolated plants on lawns. When grown in pots use a light
rich compost, taking care to insure perfect drainage. The plants must
never be allowed to become dry, as this not only checks growth but
renders them liable to attack by red spider or green fly. Another
distinctive subject for the decoration of the conservatory is =C.
grandis=, which may be described as a dwarf Chimney Campanula. The
freely branching plants, covered with attractive flowers, also form a
striking group when grown in the open border.
Altogether different in character is =C. persicifolia grandiflora=, or
the Peach-leaved Bell-flower as it is sometimes called. This plant is
lighter and more graceful than the Canterbury Bell. It throws up
handsome stems, two feet high, clothed from the ground with lance-like
leaves and elegant bells which quiver in the slightest breeze. An
interesting plant is the Giant Harebell, a dainty flower on a slender
stem, resembling the wild variety in form, but larger, richer in colour,
and a more profuse bloomer. =C. glomerata= is one of the hardiest plants
that can be grown in any garden, and the large close heads of deep blue
bells have long been familiar in herbaceous borders. For its very fine
glistening, deep blue, erect flowers, =C. grandiflora= is also a great
favourite.
Campanulas were formerly propagated by division, but this treatment has
created the impression that they are unworthy to be ranked among the
perennials. From seed, the plants are extremely robust. =C. persicifolia
grandiflora= resents division, which frequently results in weakened
growth and a tendency, especially in poor or badly drained soil, to
dwindle away. The only satisfactory method of growing Campanulas is to
raise plants annually from good strains of seed. If sown in gentle heat
early in the year--February is the usual month--many of the varieties
flower the same season. When they are well started, plenty of light and
air must be admitted. Unless intended for potting they should be planted
out in good soil where they will require no more care than is bestowed
on the borders generally. Seed can also be sown in the open ground from
May to July; transplant in autumn for flowering in the following season.
