Annuals and Biennials, Hardy.--In the majority of English gardens the
spring display of bulbous flowers is too often followed by a dreary
blank, which is almost unredeemed by a touch of colour, except that
afforded by the late Tulips and a few other flowers which are relatively
unimportant. The brilliance of the Crocuses, Hyacinths, and early Tulips
serves to throw into relief the comparative barrenness which follows.
And the contrast is rendered all the more striking by the cheerful
spring days. It is at this juncture that annuals and biennials from
summer or early autumn sowings light up the garden with welcome masses
and bands of fresh and vivid colouring. They are then so valuable that
it is surprising they are not more commonly grown, especially as the
cost of seed is very trifling. Even the transitory character of some of
them is an element in their favour, for they do not interfere with the
summer bedding arrangements. Such flowers as Pansy and Viola, however,
produce a long-continued show of bloom.

the purpose:--

Sweet Sultan
Venus' Looking-glass, purple
Virginian Stock
Viscaria

Sow thinly, not later than the middle of the month in cold districts,
but September will be early enough in the Southern counties. Drills are
preferable to broadcasting, because the beds are more easily weeded and
kept in order. Thin the rows early, so that the plants may become stout
and hard before winter overtakes them. Early in the new year
transplanting must be resorted to during open weather if the plants are
to be flowered in heavy soil; but on light, rich land, sow where they
are intended to bloom.
Annuals under Glass.--The flowers available for winter and spring
blooming are naturally few in number compared with those which fill
gardens and conservatories during the summer months. But it is not
generally realised that several favourite outdoor annuals are as
serviceable for flowering under glass in the short days of the year as
they are for growing in the open ground in summer, and they are the more
valuable for winter and spring use as no elaborate system of cultivation
is needed. Any greenhouse or conservatory from which frost can be
excluded will grow these annuals well. Seed should be sown in August or
September, in pots or pans placed in a cool house or frame. When the
seedlings have made some progress, prick them off into the pots in
which they are wanted to flower, and grow steadily on, bearing in mind
always that the most important point is to keep the plants as hardy as
possible by giving air at every favourable opportunity. The following
varieties are especially suitable for winter and spring flowering under
glass:--Alonsoa; The Star and Dunnettii varieties of Annual
Chrysanthemum; Clarkia elegans; Dimorphotheca; Gypsophila elegans;
Linaria; Nemesia Suttoni; Nicotiana, Miniature White and N. affinis;
Phlox, Purity; Salpiglossis; and Swan River Daisy.
Asters for indoor decoration should now be lifted from beds or borders
and potted. It is worth a little trouble to accomplish the task with the
least possible injury or disturbance to the roots. Light soils should
have a good soaking of water on the previous evening, to prevent the
mould from crumbling away.
Carnation.--Seed may still be sown as advised in April; but to carry
the plants safely through the winter it is necessary to have them strong
before cold weather sets in.
Chionodoxa can be forced with the same ease as Roman Hyacinths. A
48-sized pot will accommodate several bulbs.
Cinerarias are frequently placed in the open during this month and
September, and as it tends to impart a hardy constitution, the practice
is to be commended. A north border under a wall will suit them, but the
proximity of a hedge should be avoided. Before the plants are put out
see that they are quite clean, or it may be necessary to restore them to
the house in order to rid them of some troublesome pest.
Clarkia.--The varieties of the Elegans class make very handsome pot
plants, and to insure the requisite number seed must be sown in
well-drained pots during this month or early in September.
Cyclamen.--Where Cyclamens are extensively grown it is usual to make
the first sowing in August, and many gardeners regard this as the most
important period for securing healthy young seedlings. A common mistake
with beginners is to raise them in too high a temperature. On this and
other points useful suggestions will be found in the article commencing
on page 256.
Dianthus.--Either now or a little later transfer seedlings to
flowering quarters, and if possible put them into sandy loam in a sunny
spot.
Freesia.--Few and simple are the conditions necessary to the
well-being of this beautiful and delicately scented flower. The fine
specimens to be seen occasionally in cottagers' windows in the Isle of
Wight attest the ease with which it can be grown in a congenial
atmosphere. The bulbs are exceedingly small in proportion to the
flowers, and the rootlets are so fragile that potting on is to be
avoided. A 48-sized pot will hold five or six bulbs, and the soil should
consist largely of decaying vegetable fibre, such as peat, leaf-mould,
and turfy loam. The pots can be stood in any sheltered position out of
doors, under a covering of cocoa-nut fibre or other light material,
until the foliage begins to grow.
Geranium.--A sowing in August will supply plants for flowering next
summer, and the directions given in February are suitable, save that
heat can now be dispensed with. These late seedlings will need more care
to carry them through the winter than plants raised earlier in the year.
Gerbera.--These charming flowers make admirable subjects for the
greenhouse and conservatory, and an excellent display may also be
obtained outdoors if a sunny well-drained part of the garden be selected
for the plants. August is the best month for sowing seed. Plants
required for indoor blooming should be potted on as may become
necessary. Those for the open ground must be thoroughly hardened off for
planting out in the early summer of the succeeding year.
Hyacinths, Italian and Roman.--Obtain the bulbs as early as possible,
and pot them promptly. Place them in any spare corner of the open
ground, where they can be covered with cocoa-nut fibre or leaf-mould
until the roots are formed. A child can grow these flowers; and they
should be largely employed for bouquets and for indoor decoration during
the dark winter days.
Mignonette.--For winter flowering sow in 48-or 32-sized pots, filled
with light rich soil. Put the seed in little groups, thin to three or
five plants in each pot, and give them the benefit of full daylight
close to the glass. When flowering commences do not allow seed to form.
If the spikes which have passed the heyday of perfection are cut off,
the plants will break again and flower a second time.
Narcissi.--The first potting of early varieties is made this month as
soon as the bulbs can be obtained.
Pelargonium.--The remarks under Geranium apply to this flower also.
Picotee.--Follow the instructions given for Carnation.
Schizanthus.--To do full justice to this flower seed should be sown
now for plants to be kept through the winter in any house which is
sufficiently warm to exclude frost.
Scilla praecox, or sibirica.--The treatment which suits Roman
Hyacinths will answer for this bulb also, when required for flowering
indoors. The two form an admirable harmony in blue and white.
Silene.--All the most useful varieties of Catchfly are hardy against
cold, but not entirely so against damp. They possess a special value for
their sparkling appearance in spring. Sow in light sandy soil, in which
they will pass the winter safely. On a heavy loam the transplanting
system must be resorted to in February or March.
Stock, Intermediate.--This section is valuable for indoor decoration
in spring. No artificial heat is necessary to raise the seed; in fact,
it is not wise to employ it. Either in this month or early in September
sow the required number of pots and plunge them in ashes in a frame
until March. Thin the seedlings to three in each pot. Before flowering,
a rich top-dressing will be beneficial; and manure water--weak at first,
but stronger by degrees--will intensify the colours.
Stock, Spring-flowering.--A bed prepared under trees or shrubs will
afford some shelter from winter frost. Make it thoroughly rich, and in
it plant the seedlings. Should the growth be very rapid in September,
the plants will probably become too succulent to endure the stress of
winter. If so, lift them and plant again on the same spot.
Sweet Pea.--The modern culture of this delightful flower includes deep
trenching and the liberal use of manure. Those who intend to sow during
September in the open must get the trenched ground into perfect order
early in the present month. The details are important and are fully
described in the article commencing on page 303.
