Primula vulgaris. Hardy perennial
The mere name of this flower is sufficient to recall visions of spring
and perhaps of happy visits to its haunts in days gone by. But many
ardent lovers of the Primrose may not know that the strains which
are
now in favour embrace a wide range of colour, from pure white to deep
crimson or maroon, various shades of yellow and orange, and rich blue.
In fact, in a batch of seedlings nearly every plant may differ from its
companions. They all agree, however, in possessing the delicate perfume
which is characteristic of the hardy woodland favourite. Fancy Primroses
are prized as pot and border flowers, and they fully reward florists for
all the care which has been devoted to their improvement. They will
bloom satisfactorily in any shady spot; but to grow them to perfection
requires a stiff moist loam, on the north side of some hedge or
shrubbery, where glimpses of sunshine occasionally play upon them. Here
large flowers, intense in colour, will be abundantly produced far into
the spring.
The finest plants are generally obtained from a February or March sowing
made in pans or boxes. Seed may also be sown from May to July in
carefully prepared ground in the open. If inclined to take some pains in
raising the plants--and they are certainly worth it--make the summer
sowings in seed-pans in ordinary potting soil; sprinkle a little sand
over the seed, and as a finish press firmly down. Sheets of glass laid
over the pans and turned daily will prevent rapid evaporation and help
to keep the soil uniformly moist. The seedlings either may be potted
once, and then be planted out, or, if strong enough, they may be
transferred straight to flowering positions. Should this mode of
procedure be considered too troublesome, prepare a shady patch of ground
by deep digging; make it firm and level, and on this sow in shallow
drills, covering the seed very lightly. A dressing of soot over the
surface, and a cordon of ashes round it, will keep off slugs. Thin if
necessary, and when the plants are strong enough, remove to their proper
quarters. In February the buds will begin to show, and those intended
for pots should be allowed to reveal their colours before they are taken
up, so that a variety may be obtained. From a retentive soil each plant
with its surrounding earth may be taken out almost exactly of the size
required, and it should be rather smaller than the pot which has to
accommodate it. A light soil must be watered the day before the
operation, or the roots will be injuriously exposed. When potted, place
the plants in a shaded cold frame or greenhouse, allowing them plenty of
space, and withhold water until it is absolutely necessary. At first
they should be kept close, but as the roots become established gradually
give air more and more freely. Cool, slow treatment is all that is
required. Any attempt to hurry the growth will only weaken the plants
and ruin the colour of the flowers. Just before the buds open, one or
two applications of manure water will be beneficial. When the display in
pots is over, if the plants are put out in a shady border, they may
flower again late in the season.
