Greenhouse annual
The comparative ease with which the Cineraria can be well grown,
together with the exceeding beauty and variety of its flowers, will
always insure for it a high position in public favour. It is now so
generally raised from seed that no
other mode of culture need be alluded
to. The plant is rapid in growth, very succulent, thirsty, requires
generous feeding, and will not endure extremes of heat or cold. A
compost of mellow turfy loam, either yellow or brown, with a fair
addition of leaf-mould, will grow it to perfection. If leaf-mould cannot
be obtained, turfy peat will make a fairly good substitute. Soil from an
old Melon bed will also answer, with the addition of sharp grit such as
the sifted sweepings from gravel walks; the disadvantage of a very rich
soil is that it tends to the production of too much foliage.
The usual period for sowing is during the months of May and June, and,
as a rule, the plants raised in May will be found the most valuable. A
June sowing must not be expected to produce flowers until the following
March or April. It is quite possible to have Cinerarias in bloom in
November and December, and those who care for a display at that early
period should sow in April.
Cinerarias grow so freely that it is not necessary to prick the
seedlings off round the edges of pots or pans; but immediately the
plants begin to make their second leaves, transfer direct to thumb pots,
using rather coarse soil, and in doing this take care not to cover the
hearts of the plants. Place the pots in a close frame; attend to
shading, and sprinkle with soft water both morning and evening until
well established. In the second week after potting, gradually diminish
the heat and give more air. Too high a temperature, and even too much
shade, will produce thin and weak leaf-stalks. If the plants are so
crowded that they touch one another it will almost certainly be
injurious, and render them an easy prey to some of their numerous
enemies. It is far better to grow a few really fine specimens that will
produce a handsome display of superb flowers, than to attempt a large
number of feeble plants that will prove a constant source of trouble,
and in the end yield but a poor return in bloom. Endeavour to grow them
as nearly hardy as the season will allow, even admitting the night air
freely on suitable occasions. Immediately the thumb pots are filled with
roots, shift to a larger size, and it is important that this operation
should not be delayed a day too long. To the practised eye the
alteration of the colour of the leaves to a pale green is a sufficient
intimation that starvation has commenced, and that prompt action is
necessary to save the plants. It is the custom of some growers to
transfer at once to the size in which they are intended to bloom. There
is, however, some danger to the inexperienced in over-potting, and
therefore one intermediate shift is advisable. As a rule 32-size pots
are large enough, but the 24-or even the 16-size is allowable when very
fine specimens are required. The seedlings should be in their final
pots not later than the end of November.
It will help to harden and establish the plants if they are placed in
the open air during August and September. A north border under the
shelter of a wall or building is the most suitable spot, but avoid a
hedge of any kind. Clear away suckers, and if many buds are presented,
every third one may be removed when very fine blooms are wanted. From
the first appearance of the buds, manure water can be given with
advantage once or twice a week until the flowers show colour, and then
it should be discontinued.
Although Cinerarias are thrifty plants, they are fastidious about
trifles. If possible give them new pots, or see that old ones are made
scrupulously clean. Even hard water will retard free growth, oftentimes
to the perplexity of the cultivator.
A host of enemies attack Cinerarias; indeed, there is scarcely a pest
known to the greenhouse but finds a congenial home upon this plant.
Mildew is more common in some seasons than in others. As a rule, it
appears during July and August, especially after insufficient
ventilation, or when the plants have been left too long in one place or
too near to each other. Obviously weakness invites attack, and the
necessity of robust and vigorous growth is thus effectually taught. On
the first appearance of a curled leaf, dust the foliage and soil with
sulphur, and give no water overhead until a cure has been effected. The
aphis is easily killed by fumigation carried out on a quiet evening.
Some gardeners prefer to give an hour or two once a week to the removal
of the pest by means of a soft brush. From three to four dozen plants
are easily cleansed by hand in the time named.
Star Cinerarias (C. stellata) are grown under precisely the same
conditions as the Florists' or Show Cinerarias, and this type of flower
is highly valued for its singular gracefulness and beautiful decorative
effect. In the conservatory and on the table it is an indispensable
plant. The sprays admit of most charming arrangements in vases with any
kind of ornamental foliage, and maintain their beauty for a long time in
water.
Intermediate Cinerarias.--These new types of Cineraria, which in habit
are intermediate between the Large-flowered and Stellata classes, make
admirable subjects for table decoration, as well as for the adornment of
the conservatory or greenhouse. In this class the Feltham Beauty strain
undoubtedly has a great future before it. Originated at the Feltham
Nurseries, this strain has attracted considerable attention at the
numerous horticultural meetings where it has been exhibited, and since
it passed into our hands a few years ago some very beautiful colours not
to be found among the ordinary Stellata varieties have been added to it.
The distinctive feature of the flowers is the white centre, which
greatly enhances the vividness of the colouring of the petals. For the
Intermediate section the same methods of culture as advised for the
other classes of Cineraria will apply.
