==PHLOX DRUMMONDII==
==Half-hardy annual==
Those who are acquainted with the older forms of this annual might fail to recognise a friend under its new and improved appearance. There are now several beautiful types, each possessing characteristics of its own, and all producing flowers that are perfect in form and brilliant in colour. The large-flowered section produces splendid bedding plants, but the dwarf compact varieties are also highly prized for effective ma.s.sing and general usefulness. The latter attain a height seldom exceeding six inches, and are therefore eminently suitable for edgings and borders, as well as for bedding. They bloom profusely for a long period, not only in the open ground, but also as pot plants in the greenhouse or conservatory, where they are conspicuous for the richness of their display.
For early flowering sow seed of all the varieties in February or March in well-drained pans or shallow boxes. Any good sifted soil, made firm, will suit them, and every seed should be separately pressed in, allowing about an inch between each; then cover with fine soil. This will generally give sufficient s.p.a.ce between the plants to save p.r.i.c.king off; but if the growth becomes so strong as to render a transfer necessary, lift every alternate plant, fill the vacant spots with soil, and those left will have room to develop. Pot the plants that are taken out, give them a start in a frame, and shade from direct suns.h.i.+ne. Phloxes should not be coddled; the best results are always obtained from st.u.r.dy plants which have been hardened as far as possible by free access of air from their earliest stage of growth. This does not imply that they are to be rudely transferred from protection to the open air. The change can easily be managed gradually until some genial evening makes it perfectly safe to expose them fully. A s.p.a.ce of about two feet each way is required for each plant of the large-flowered cla.s.s, but a more modest allowance of nine or twelve inches will suffice for the dwarf varieties.
Before they are put out the plants must be free from aphis; if not, fumigation should be resorted to once or twice until there is a clearance of the pest. Seed of the annual Phlox may also be sown in the open ground during the latter part of May, and the plants will flower abundantly from mid-August until frost destroys them.
The employment of Phlox as pot plants has already been alluded to, but special mention must be made of Purity, which is by far the most valuable of all the varieties for blooming indoors. The pure white flowers, which are sweetly scented, may be produced at almost any period of the year. They are, perhaps, more highly appreciated at Easter than at any other time, and to insure a display at that season seed should be sown in September or October. The plants will do well if grown on in a cold frame, the final s.h.i.+ft being into pots of the 48-size. When grown under gla.s.s, Phlox should be given treatment as nearly hardy as possible, all that is necessary in regulating temperature being the exclusion of frost from the greenhouse or frame.
==PHLOX, PERENNIAL==
==Hardy perennial==
The seed of perennial Phlox is very slow and erratic in germinating, and from a sowing made in September the seedlings may not appear until the following spring. Seed may also be sown in the first week of March in shallow boxes, and put into moderate heat. In due time p.r.i.c.k out into boxes filled with light rich soil, and having hardened them in the usual way, plant out a foot apart in a good bed, and help, if needful, with an occasional watering.
==PICOTEE==
==Dianthus Caryophyllus fl. pi. Hardy perennial==
Seedling Picotees are extremely robust and free-flowering, and seed saved from the best types will produce handsome specimens. The instructions for growing Carnation--sowing in pans from April to August and transplanting when large enough--are equally applicable to the Picotee.
==PINK==
==Dianthus plumarius. Hardy perennial==
This old English flower is valued in every garden. Both the double and single varieties are easily raised from seed and the plants bloom with the greatest freedom. Seed may be sown any time from April to August.
Treat the seedlings in the manner advised for Carnations, and in due course transfer to open quarters. The foliage maintains its colour during the severest winter, and is therefore worth consideration for furnis.h.i.+ng the border, to say nothing of the abundant display of perfumed flowers which the plants afford in early summer.
==POLYANTHUS==
==Primula (veris) elatior. Hardy perennial==
A sowing in February or March in pans will produce strong specimens for flowering in the following year. Or seed may be sown from May to July on a shady border. p.r.i.c.k off the seedlings when large enough to handle. The plants should never flag for want of water, and green fly must be kept down by syringing. Some good solution will be necessary against red spider if through starvation in a dry situation it has been permitted to gain a footing. All the varieties can be grown in a bed with a cool shaded aspect. They do not require a rich soil; a strong and fibrous loam with a little leaf-mould is sufficient. On pa.s.sing out of flower the plants will split up into several heads, when they may be separated and potted singly. Exquisite colour effects can be created by planting Polyanthus in a.s.sociation with beds of Tulips for flowering in April.
==POPPY==
==Papaver. Hardy annual and hardy perennial==
The recent developments of this flower have brought it into great and deserved popularity, and it may be safely affirmed that few other subjects in our gardens afford a more imposing display of brilliant colouring during the blooming period. The delicate beauty of the s.h.i.+rley Poppies is alone sufficient to create a reputation for the entire cla.s.s, and the huge flowers of the double varieties make a gorgeous show. All the varieties are eminently adapted for enlivening shrubbery borders and the sides of carriage-drives.
Seeds of Annual Poppies should be sown where the plants are intended to flower, because it is difficult to transplant with any measure of success. During March or April sow in lines or groups, =and thin to about a foot apart=. Large clumps of some of the bolder colours should be sown in spots that are visible from a distance, and they will present glowing ma.s.ses of flowers.
By sowing seeds of Perennial Poppies in pans in March, and putting out the seedlings when large enough, the plants will flower the same year.
The more general practice, however, is to sow very thinly on a well-prepared border any time from May to August. Keep the seedlings free from weeds, and thin out if necessary. The plants may be transferred to permanent quarters early in autumn or in the spring months.
==PORTULACA==
==Purslane. Half-hardy annual==
This is a splendid subject when the weather favours it. In a dry hot season, and on a sandy soil, Portulacas can be grown as easily as Cress.
Sowings are sometimes made early in the year in greenhouses or frames; but as a rule it is a vain attempt. Wait until May or June, when the weather appears settled; then put the seed into the open border, and the lighter the soil, and the hotter the season, the more brilliant will be the display of flowers. Sow on raised beds, in rows six or nine inches apart, and cover the seed with sand or fine earth. If the plants appear to be injuriously close they must be thinned. Should a period of rain ensue, the raised beds have a distinct advantage over a flat surface, and rows afford opportunity for stirring the soil and keeping down weeds.
==PRIMROSE==
==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 suns.h.i.+ne 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 gla.s.s 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 s.p.a.ce, 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.
==PRIMULA SINENSIS==
==Chinese Primrose. Greenhouse annual==
The history of the Chinese Primula since it first reached this country has an almost romantic interest. As originally received the flower was, and now is, insignificant in size and miserably poor in colour. But florists at once perceived in it immense possibilities. The result of their labours, extending over many years, may be seen in the magnificent Single, Double, and Star Primulas which now adorn conservatories, greenhouses, and homes. From so small a beginning the range of colours is amazing; there are snowy-white flowers in several beautiful forms, a pure Cambridge blue, rich violet-blue, many shades of rose, pink, scarlet, and gorgeous crimson. Almost equally striking is the improvement in the foliage, especially the introduction of the fern-leaf, with its diverse shades of green and richly toned under-surface.
To enjoy the bloom for a long period make successive sowings in May and June. A further sowing may be made in July if necessary. Use new pots which have been soaked in water; but if these are not at hand, scrub some old pots clean, for Primulas are fastidious from the outset, and it is by apparent trifles that some growers produce plants so immensely superior to others treated with less care. Provide free drainage, and place a little dry moss over the crocks. Any fairly good rich soil will be suitable, but a mixture of equal parts of sound fibrous loam and leaf-mould, with a small addition of silver sand, is best. Press this compost firmly into the pots to within half an inch of the top. Water before sowing, and sprinkle sufficient sand over the surface to cover the soil. On this sand sow evenly and thinly, for it is well known that the finest new Primula seed comes up irregularly, and a thin sowing admits of the removal of plants that may be ready, without disturbing the remainder. Cover the seed with just enough fine soil to hide the sand, and gently press the surface. Place the pots in a sheltered part of the greenhouse, protected from draughts and direct sunlight; a small glazed frame will be useful for this purpose. While the seed is germinating the temperature should not rise above 70, or fall below 50. Immediately the plants are large enough, p.r.i.c.k off round the rim of small pots, and if convenient place them in a propagating box. Water with care, and shade if necessary. When established give air, which should be daily increased until the plants will bear placing on the greenhouse stage. Transfer singly to thumb pots, and subsequently s.h.i.+ft into larger sizes as may be requisite, but never do this until the pots are filled with roots, and always put the plants in firmly up to the collar. During July, August, and up to the middle of September expose freely to the air in any convenient position where shelter can be given in unfavourable weather.
Where there is no greenhouse, but only a hot-bed, it is still possible to grow good Primulas, with care and patience. The instructions given for treatment in the greenhouse may easily be adapted to the pit or frame, only there must be a little more watchfulness in affording shade on sunny days to prevent overheating.
Endeavour to give the plants a robust const.i.tution from the first, for weak, rickety things cannot produce a satisfactory bloom. Primulas need a long period of growth before they flower; hence they should never be subjected to a forcing temperature. Sufficient heat must be provided to raise the plants, but afterwards the aim should be to render Primulas as nearly hardy as possible before cold weather sets in. There must, however, be ample protection against frost, damp, and cutting winds.
==Primula stellata== (=Star Primula=).--This elegant strain of Primula, introduced by us in 1895, has attained a high position in popular favour. Although it is not intended to supersede or compete with the splendid strains of =P. sinensis=, it is a most valuable addition to the conservatory, and will be found indispensable for general decorative work. The plants are unusually floriferous and continue in bloom for a long time. When cut, the sprays travel well and remain fresh in water many days. For table adornment Star Primulas are unsurpa.s.sed by any other greenhouse flower at their own period of the year. The culture is precisely the same as for =P. sinensis=.
==Half-hardy Primula==.--This section, which embraces a number of very charming species, includes the well-known =P. obconica grandiflora,= which is almost perpetual-blooming under gla.s.s. Seed of this Primula may be sown from February to July, from the earliest of which the plants will flower in autumn and continue to bloom throughout the winter. In the early stages the seedlings may be managed as already directed for =P. sinensis=, bearing in mind that excessive watering should be avoided. Cool greenhouse treatment will suit the plants well.
Another half-hardy variety which has recently attained wide popularity is =P. malacoides=. The dainty flowers are produced tier upon tier to a height of about two feet and are very sweetly perfumed. For a winter display sow in February, and successional sowings may be made until July. =P. malacoides= especially resents a forcing temperature.
Therefore the culture should be as nearly hardy as possible, and even in the seedling stage the plants must have free access of air on all suitable occasions, or they are very liable to damp off.
==Hardy Primula.==--A number of very elegant garden Primulas are worthy of attention. The majority answer well when grown in borders, but they are especially at home in rock or Alpine gardens. The family is now so large and so variable in time of blooming that it is possible to have the different species in flower during almost every month of the year. As a rule, it is advisable to raise the seedlings in pots or pans placed in a frame or greenhouse, and to transfer them to the open ground when thoroughly hardened off.
==RANUNCULUS==
==Half-hardy perennial==
The Ranunculus can be grown either from seed or from roots. The seed is thinly sown from January to March, in boxes four to six inches deep, filled with good soil. A cool greenhouse or frame is the proper place for the boxes until the spring is somewhat advanced. A little extra care is requisite to insure free growth and a hardy const.i.tution, and the roots should not be turned out of the boxes until they have ceased growing and are quite ripe; then they may be stored for planting in November or February.
