Chapter XIV: Part 14

Text size

Geraniums of all kinds are most valuable if treated as annuals. In their seedling state the plants are peculiarly robust and charmingly fresh in leafage and flowers, even if amongst them there does not happen to be one that is welcome as a novel florist’s flower. When grown from first-class seed, however, a large proportion of fine varieties and a few real novelties may be expected. The seed may be sown on any day throughout the year, but February and August are especially suitable. Sow in pans filled with a good mixture, in a somewhat rough state. Cover with a fair sixteenth of an inch of fine soil. Put the seed-pans in a temperature of 60° to 70° if sown in February, but heat will not be necessary at all unless it is desired to bring the plants into flower early in the ensuing summer. We are accustomed to place the seed-pans on a sunny shelf in a cool greenhouse, and have fine plants by the end of June, many of which begin to flower in August.

GERBERA

Half-hardy perennial

The Gerbera, also known as the Barberton or Transvaal Daisy, is a native of South Africa. Under cool greenhouse treatment it may be grown to perfection in pots, and a charming display of bloom can also be obtained in the open border from plants put out in a well-drained sunny position and given slight protection in winter. The flowers somewhat resemble a Marguerite in form, having a number of long pointed petals radiating from a small centre. In addition to the brilliant _G. Jamesonii_, sometimes called the Scarlet Daisy of the Cape, many hybrid flowers having a wide range of delightful colours are also available. Although seed is often sown in spring, the best results are probably obtained from an August sowing, in pans placed in a gentle heat. Prick off the seedlings when large enough, and if required for the greenhouse or conservatory transfer to pots, or gradually harden off for planting in the open as soon as weather permits in the following spring.

GESNERA

Nægelia. Tender perennial

An extremely beautiful ornament for stove or conservatory. The new hybrids freely produce spikes of bright pendulous flowers of many charming colours. Although the Gesnera is a perennial, it is sound practice to treat the plant as an annual. Seedlings from a January sowing will commence flowering in about nine months. Very rich soil, a warm and even temperature, and plenty of water, are requisite to promote luxuriant growth. The culture advised for Gloxinias will exactly suit the Gesnera also.

GEUM

Hardy perennial

The introduction of the well-known double variety, Mrs. Bradshaw, which may easily be flowered from seed in the first season, has brought the Geum into prominence in recent years. Seed of the above-named variety should be sown in pans in March or April and the seedlings pricked off into boxes of rich soil when large enough. Put out in May or June and do not let the plants suffer for want of water. Geums may also be raised from sowings made in June or July, and transplanting in due course to permanent quarters, in the manner usual with hardy perennials.

GLADIOLUS

Corn Flag. Half-hardy perennial

Formerly the Gladiolus was seldom raised from seed, probably because the seed obtainable was not worth sowing. Now it is saved with so much care that it will give a splendid display of flowers, a large proportion of which will be equal to named sorts, and some may show a decided advance.

The use of large pots—the 32-size will answer—is advantageous for many reasons, and they should be either new or scrupulously clean, for they will have to remain unchanged for many months, so that a fair start is the more necessary. For the same reason special care should be taken to insure free drainage. Over the usual crocks place a layer of dry moss, and fill with a compost of fibrous loam and leaf-mould in equal parts, with sufficient sharp sand added to make it thoroughly porous. Press the soil firmly into the pots, making the surface quite even, and in February dibble the seeds separately about an inch apart, and half an inch deep. This will render it needless to disturb the seedlings during the first season. Put the seed-pots in a steady temperature not exceeding 65° or 70°. After watering, it will help to retain the moisture if the top of each pot is covered with a layer of _old_ moss, until the plants show. When the seedlings are about an inch high remove to a lower temperature, and begin to harden off by giving air on suitable occasions. Take care, however, that in the process no check is given to growth. Soon after the middle of May the seedlings should be able to bear full exposure, and it will then be time to renew the surface soil. Gently remove the upper layer, and replace it with rotten cow-manure, or some other rich dressing. Water must be given regularly until about midsummer, when the pots may be plunged to the rim in a shady border, and this will keep them tolerably moist until, in September, the seedlings begin to ripen off, which they must be allowed to do. When the leaves have died down, shake out the bulbs and place them on a shelf to dry. A mixture of equal parts of peat and pine sawdust, placed in a box or seed-pan, will make the best possible store for them; the box or seed-pan to be kept in any spot which is safe from heat and frost. After about six weeks, each bulb should be examined, and decayed specimens removed. If any of them have commenced growing, pot them and place in a pit or greenhouse. In March take the bulbs out of store, pot each one singly, and prepare for planting out. The transfer to the open must not be made until the danger of frost is past, even though it be necessary to wait until the first week of June.

Further remarks on Gladiolus will be found at page 329, under ‘The Culture of Flowering Bulbs.’

GLOXINIA

Tender perennial

Gloxinias can now be flowered in the most satisfactory manner within six months from the date of sowing seed. Hence there is no longer the least temptation to propagate these plants by the lengthy and troublesome method formerly in vogue, especially as seedlings raised from a first-class strain produce flowers of the finest quality, both as to form and style of growth. One great advantage to be obtained from seedlings is an almost endless variety of colour, for the careful hybridisation of the choicest flowers not only perpetuates those colours, but yields other fine shades also. Those who have never seen a large and well-grown collection of seedling Gloxinias have yet to witness one of the most striking displays of floral beauty.

Quite as much has been done for the foliage of the Gloxinia as for its flower, and the best strains now produce grand leaves which are reflexed in such a manner as almost to hide the pot, so that the foliage presents an extremely ornamental appearance.

By successive sowings and judicious management it is possible to flower Gloxinias almost the year through. The most important months for sowing seed are January, February, and March, and to secure an early display in the following spring some growers sow again in June or July.

The soil most suited to Gloxinias is a light porous compost of fibrous loam. If this is not obtainable, leaf-mould will answer, mixed with peat and silver sand in about equal parts. New pots are advisable, or old ones must be thoroughly cleansed, and free drainage is essential to success. Fill the pots to within half an inch of the top. Sow thinly, and slightly cover the seed with very fine soil. Place the pots in a warm, moist position, carefully shading from the sun. A light sprinkling of water daily will be necessary. Immediately some plants are large enough for shifting, lift them tenderly from the seed-pot, so as scarcely to disturb the rest, and prick off into large 60-pots in which the soil has a convex surface. Follow this process as plants become ready until all the seedlings have been transferred. When potting on allow the leaves to rest on the soil, but avoid covering the hearts. On the first warm day give air on the leeward side of the house, briefly at first, and increase the time as the plants become established. A clear space between the plants is necessary to prevent the leaves of neighbours from meeting. The final shift should be into 48-pots, unless extra fine specimens are required, and then one or two sizes larger may be used. An occasional dose of weak manure water will prove beneficial, taking care that the foliage is not wetted. A moist atmosphere, with the temperature at about 60° to 65°, greatly facilitates the growth of Gloxinias. With care, however, they may be well grown in greenhouses and pits heated by hot water. Although the plants love a humid atmosphere while growing, this ceases to be an advantage, and, in fact, becomes injurious when the flowers begin to expand. At that time, also, the manure water should be discontinued.

Under ‘The Culture of Flowering Bulbs,’ page 331, further instructions are given.

GODETIA

Hardy annual

So far as the culture of Godetias is concerned, the usual spring sowing and the regular treatment of hardy annuals will satisfy those who are content with a display entailing the least possible trouble. But the Godetia is no ordinary annual. The plants flower with such amazing profusion, and the colours are so magnificent, that those who wish to produce striking effects in beds or borders in July and August will find Godetias of the highest value. All the varieties come perfectly true to colour and admit of numerous contrasts and harmonies. As an example, we suggest the following combination for a long border, or beside a carriage drive. Sow two rows of Alyssum minimum, allowing twelve inches between the rows; one row of Dwarf Pink Godetia fifteen inches from the Alyssum; two rows of G. Dwarf Duchess of Albany eighteen inches apart; one row of G. Scarlet Queen eighteen inches from the preceding variety, and one row of Double Rose at the back. The result will astonish those who have not previously seen a really fine exposition of this flower. Many other combinations will occur to those who carefully study colour schemes.

There are few annuals more greatly valued for cutting than the taller varieties of Godetia. These mainly produce double flowers in sprays two feet or more in length which develop into full beauty after being placed in water.

March and April are the months for sowing seed in the open for a summer display, and September for spring flowering. Good effects, however, are obtained by raising a sufficient number of plants in boxes and pricking off in readiness for putting out after bulbs and spring bedders have been cleared away. Under this practice there need not be a blank or a defective specimen.

Dwarf Godetias make exceedingly symmetrical and attractive pot plants. For this purpose sow seed in October in pans and place them in a temperature of 55° until the seedlings appear, then remove to a cooler place. As soon as possible prick off three in each 48-pot and when established grow on during winter in cold frames, giving air daily except in frosty weather, when the frames must remain closed and can be protected with whatever covering may be at hand. Here it may be well to point out that even when touched by frost the plants will recover if they are shaded from the sun’s rays until the pots are quite clear of frost. Godetias flowered in pots make bright groups in conservatories, and occasionally do good service where failures occur in beds.

GREVILLEA ROBUSTA

Australian Oak. Greenhouse shrub

In its native country, New South Wales, this is a stately tree. Here it is grown as a pot plant, and the finely cut, drooping, fern-like foliage produces one of the most graceful decorative subjects we possess. Its value is enhanced by the fact that it withstands the baneful influences of gas, dust, and changes of temperature better than the majority of table plants.

Seedlings are easily raised by those who can exercise patience; and afterwards the simplest cool culture will suffice to grow handsome specimens. But we do not know any seed—not even the Auricula—which takes more time and is so capricious in germinating. In all cases where seed is sown in fairly rich soil, which has to be kept constantly moist and undisturbed for a long period, there is a tendency to sourness, especially on the surface. Free drainage will do something towards preventing this. Another aid in the same direction is to cover the seed with a layer of sand, and the sand with a thin coating of ordinary potting soil. When the surface becomes covered with moss, the coating of soil can be gently removed down to the sand, and be replaced with fresh earth, without detriment to the seeds.

Sow at any time of the year, in 48-sized pots filled with rather firm soil; and as the seedlings straggle through and show two pairs of leaves, pot them off singly, and give the shelter of a close pit or frame until they become established. They must not be allowed to suffer for lack of water, but there is no necessity to give them manure water at any stage of growth. An occasional re-potting is the only other attention they will require until they reach the final size, and the pots need not then be large.

HOLLYHOCK

Althæa rosea. Hardy perennial

Generations of unnatural treatment had so debilitated the Hollyhock that disease threatened to banish it from our gardens. Just at the critical time it was discovered that the plant could be grown and satisfactorily flowered from seed. Florists at once turned their attention to the production of seed worth growing, and with marked success. The best strains may now be relied on to produce a large proportion of perfectly formed double flowers, imposing in size, colour, and substance. The seedlings also possess a constitution capable of withstanding the deadly _Puccinia malvacearum_, and there is no longer a danger that this stately plant will become merely one of the pleasures of memory.

In growing the Hollyhock it is necessary to remember that a large amount of vegetable tissue has to be produced within a brief period, so that the treatment throughout its career should be exceptionally liberal. Some gardeners are successful in flowering Hollyhocks as annuals. Where this course is adopted it is usual to sow in January in well-drained pots or seed-pans filled with rich soil freely mixed with sand, covering the seed with a slight dusting of fine earth. A temperature of 65° or 70° is necessary, and in about a fortnight the plants should attain a height of one inch, when they will be ready for pricking off round the edges of 4-1/2-inch pots, filled with a good porous compost. Put the seedlings in so that the first leaves just touch the surface. At the beginning of March transfer singly to thumb pots, and immediately the roots take hold remove to pits or frames, where they can be exposed to genial showers and be gradually hardened. Defer the planting out until the weather is quite warm and settled.

The shrubbery border is the natural position for the Hollyhock, but the regular occupants keep the soil poor, and for such a rapid-growing plant as we are now considering there is obviously all the greater need for deep digging and liberal manuring. If put out during dry weather, complete the operation with a soaking of water, and repeat this twice a week until rain falls. Give each plant a clear space of three or four feet to afford easy access for staking and watering. By midsummer offshoots will begin to push through the soil. The removal of these will throw all the strength of the plant into one stem. To insure its safety a strong stake will be required, which should be firmly driven into the ground, and rise six or seven feet above it. In case of an accident at any time to the central stem the hope of flowers for that year is gone, and it is therefore worth some pains to prevent a mishap. The tying must be done with judgment, and as the plants increase in size an occasional inspection will save the stems from being cut. Several inches of half-decayed cow-manure placed round the stems, with a saucer-like hollow in the centre to retain water, will be helpful to the roots, and if the flowers are intended for exhibition, the treatment can scarcely be too generous.

It is, however, easy to grow and flower Hollyhocks without the aid of artificial heat. On a south border in June prepare drills about two inches deep and a foot apart. Place an inch of rich sifted soil in each drill, and upon this sow the seed very thinly, covering it about a quarter of an inch. If the weather be dry, give a gentle soaking of water, and finish with a dusting of soot to prevent vermin from eating the seedlings. Thin the plants to six inches apart, and they may remain in the seed-rows until the end of September. Whether they are then transplanted straight to blooming quarters, or put into a cold frame for the winter, depends on soil and climate. In the southern counties, and on light land, it will generally be safe to winter Hollyhocks in the open, with merely a shelter of dry fern or litter. But in heavy loam or clay the risk is too great, and the cold frame must be resorted to. In this they will be secure, and can be ventilated as weather permits. As the season advances give more air, until they are planted out in May. Seed may also be sown in pans in July or August, the seedlings being transferred in due course to pots for the winter. The protection of a frame will suffice, provided that frost is kept away, and the plants may be put out in spring as already advised.

IMPATIENS

Sultan’s Balsam. Tender perennial

Early sowing should be avoided for two reasons. The seed germinates but slowly in dull weather, and the seedlings when raised are almost certain to damp off. We do not advise a start before March, and not until April unless a steady heat of 60° or 65° can be maintained. Sow in well-drained pots, filled with soil composed of two parts of turfy loam and one part of leaf-soil, with very little sand added. The seedlings are exceedingly brittle at the outset, and re-potting should not be attempted until they are about an inch high. Even then they need delicate handling, and after the task is accomplished they should be promptly placed in a warm frame or propagating pit for a few days. In June or July the plants should reach 48-sized pots, but they must not be transferred to the conservatory without careful hardening, or the whole of the flowers will fall. _I. Holstii_ also succeeds well when bedded out in summer in the same manner as Begonias.

JACOBEA—_see_ SENECIO

KOCHIA TRICHOPHYLLA

Half-hardy annual

This remarkable variety of _K. scoparia_ is a miniature annual shrub, which is also known as Summer Cypress, or Belvidere. It is singularly attractive, of rapid growth and graceful habit. In a very brief time the finely cut foliage forms a compact cylindrical plant, beautifully domed at the top, and the tender green changes to a rich russet-crimson in autumn.

Seed may be sown in slight heat during February or March to provide early plants for pots, or for setting out in the open immediately the bedding season commences. It is important not to crowd the seedlings, and every precaution should be taken to prevent them from becoming thin, leggy, or wanting in symmetry. Each plant must be allowed sufficient space to develop equally all round. An April sowing can be made in the open where the plants are intended to remain, and beyond regular thinning they will give very little trouble.

As a conspicuous dot plant in beds this Kochia is extremely useful, or it can be massed in borders, and it also forms an admirable dividing line in the flower garden. For the decoration of conservatories a number should be specially reserved. Specimens may be employed with striking effect on flights of steps, in halls, and many other positions where a plant of perfect outline will serve as an ornament. Height, 2 to 3 feet.

LARKSPUR

Hardy annual

The cultivation of the annual Delphiniums, more familiarly known as Larkspurs, is so simple in character that it calls for little comment. But these handsome subjects are so widely grown, and so greatly appreciated, that they are fully deserving of special mention here. The taller varieties, of which the Stock-flowered strain is the most popular, are best grown in large beds, borders and shrubberies, and the dwarfer kinds in small beds. Apart from their usefulness in the garden, however, the taller sorts of Larkspur are much in request for providing cut material, particularly for the decoration of the dinner-table, and a number of plants should always be grown in reserve for this purpose. It is usual to put in the seed where the plants are intended to stand, and March and April are the best months for sowing. Thin out the seedlings promptly, and give each plant ample room for development, especially when grown on good ground.

Larkspurs may also be sown in September for producing an earlier display in the following year than is possible from spring-sown seed.

LAVATERA

Mallow. Hardy annual and hardy perennial

Countryside gardens owe not a little of their floral brightness to the Mallows. The modern varieties of Lavatera, however, far surpass in effectiveness the flowers commonly met with and are regarded as among the finest subjects for creating an imposing display in tall borders and large beds. For this purpose the annual varieties, Loveliness, _Rosea splendens_, and _Alba splendens_, are the most popular. As transplanting is not to be depended upon, seed should be sown thinly in March, April or May where the plants are wanted to flower. If the ground has been generously prepared fine specimens will result, and each plant should be allowed a spacing of at least two feet for development.

The perennial variety, _L. Olbia_, makes a bold subject for herbaceous borders and shrubberies. Seed may be sown in pans any time from March to August, putting out the plants when large enough for flowering in the following season. Small plants of this variety may with advantage be potted for conservatory decoration.

LOBELIA

Annual and perennial; half-hardy

There are several distinct classes of Lobelia, differing materially in height and habit. For dwarf beds or edgings the _compact_ varieties should alone be used. These grow from four to six inches high, and form dense balls of flowers. The _spreading_ or _gracilis_ class, including _L. speciosa_ and _L. Paxtoniana_, is in deserved repute for positions which do not demand an exact limit to the line of colouring. The plants also show to advantage in suspended baskets, window boxes, rustic work, vases, and any position where an appearance of graceful negligence is aimed at. The _ramosa_ section grows from nine to twelve inches high, and produces much larger flowers than the classes previously named.

All the foregoing can be treated as annuals; and from sowings, made in February or March plants may be raised in good time for bedding out in May. Use sandy soil, and place the seed-pans in a temperature of about 60°, taking care to keep them moist. By the end of March or beginning of April the seedlings will be ready for transferring to pots, pans, or boxes. The last named are very serviceable for this flower, for they afford opportunity of giving the seedlings sufficient space to produce a tufty habit of growth. A gentle heat will start them, and they will give no trouble afterwards, except on one point, which happens to be of considerable importance. It is that the plants should never be allowed to produce a flower while in pots or boxes. Pick off every bud until they are in final positions, and then, having taken hold of the soil, they will bloom profusely until the end of the season.

Lobelias make elegant pot plants, yet, with the exception of the _ramosa_ varieties which are excellent for the purpose, they cannot be grown satisfactorily in pots. The difficulty is easily surmounted by putting them out a foot apart in a good open position, and if possible in a rather stiff soil. When they have developed into fine clumps lift them with care and place them in pots, avoiding injury to the roots. This method will produce a display of colour which cannot be attained by exclusive pot culture.

From the best strains of seed it is possible that a few plants may revert to long-lost characters. Florists are striving to obviate this, but it will require time. Meanwhile there are two ways of dealing with the difficulty. Some growers prefer to raise plants from seed, and take cuttings from approved specimens for the next season. This plan insures exactitude in height and colour, with almost the robust growth and free-flowering qualities of seedlings. But it necessitates holding a stock through the winter, and this may be a serious matter to many. The simpler proceeding, and one which answers well in practice, is to raise seedlings annually and to remove from the pans or boxes any plants which show the least deviation from the true type. A few kept as a reserve will replace faulty specimens which may be detected after planting out.

The handsome perennial section of Lobelias obtains less attention than it deserves, especially as the most ordinary routine culture will suffice for these plants. They are partial to moisture, and also to a deep rich loam. A sowing on moderate heat in February or March will secure plants fit for bedding out in May. They may also be grown entirely without the aid of artificial heat from sowings in June or July. Employ pots or seed-pans, and pot off singly immediately the plants are large enough to handle. The protection of a cold frame or hand-light is all that is necessary during winter, and the planting out may be done in May. These Lobelias reach two feet in height, and make excellent companions to such flowers as _Anemone japonica alba_ and _Hyacinthus candicans_. The dark metallic foliage and dazzling scarlet flowers also have an imposing effect as the back row of a ribbon border.

LUPINUS

Lupine. Hardy annual and hardy perennial

Both the annual and the perennial Lupines are extremely valuable for garden decoration and for supplying an abundance of cut blooms. Each class includes a number of charming colours and many of the flowers are delightfully scented. Not the least of their merits is the fact that Lupines are not particular as to soil; indeed, the annual sorts will often thrive on ground that is too poor for other and more fastidious subjects.

The annual varieties should be sown where intended to flower, as they do not transplant well. Sow the seed in March, April, or May, and subsequently allow each specimen a space of about eighteen inches for development.

_L. polyphyllus_ is a valuable race of perennial Lupines which, from a sowing made in March or April and treated as annuals, will produce a fine show in the following autumn. In order to insure a display earlier in the season, however, many growers of these flowers prefer to sow in June and July of the preceding year. Two varieties of _L. arboreus_ form large bushes which are distinctly ornamental when in full bloom. The seed should be sown in June or July and the seedlings transplanted to flowering positions before they become very large.

MARIGOLD

Tagetes. Half-hardy annual

Marigolds of several classes are valued for the profuse display of their golden flowers in the later summer months. The choicest are the so-called French, or _Tagetes patula_, which have richly coloured flowers, and some of the varieties are beautifully striped. For their high quality these Marigolds are judged by the florists’ standards. The African, or _Tagetes erecta_, make large bushy plants with flowers ‘piled high’ in the centre; the colours are intense orange and yellow. in various shades. The bedding section is represented by the dwarf varieties of _Tagetes patula_, or Dwarf French Marigolds; also by _Tagetes signata,_ a very neat plant with fine foliage and rather small orange-coloured flowers, produced in great abundance. In hot seasons and on dry soils this proves an admirable substitute for the Calceolaria, which does not thrive when short of food, whereas the Tagetes bears drought, the shade of trees, and a poor soil with patience, and up to a certain point with advantage. Sow all these in March in a moderate heat, and prick the plants out in the usual way, taking care finally to allot them sunny positions. Seed may also be sown in the open ground at the end of April or early in May.

The section of Pot Marigolds, _Calendula officinalis_, includes two remarkably handsome varieties, Orange King and Lemon Queen; the flowers of both are large, double, perfectly formed, and are worth a place in the choicest garden. These may be sown on the open border in March, April, and May, and the best place for them is in the full sun on a rather dry poor soil, but they are not particular, provided they are not much shaded.

MARVEL OF PERU

Mirabilis Jalapa. Half-hardy perennial

This flower may be treated either as an annual or as a biennial. As an annual the plants are very compact and effective, the leaves and flowers forming round glittering masses in the late summer and autumn months. When the roots are saved through the winter and planted out in April larger plants are obtained, but there is no advance in quality over the very neat and sparkling specimens raised from seed in spring. Sow in heat in March and April, and treat in the same manner as Balsams until the time arrives for planting out. A rich sandy loam suits them, and they like full exposure to sunshine.

MIGNONETTE

Reseda odorata. Hardy annual

Mignonette is so much prized that we must devote to it a paragraph, although there is little to be said. In many gardens plants appear year after year from self-sown seeds, and it will therefore be evident that Mignonette may be grown with the utmost simplicity. As a border plant we have but to sow where it is to remain, at different times from March to midsummer; the one important point is to make the bed very firm; in fact the soil should be trodden hard. It is imperative to thin early and severely, for any one plant left alone will soon be a foot in diameter, and in some circumstances cover a much larger area. Where bees are kept and space can be afforded, seed should be sown in quantity, for Mignonette honey is of the finest quality in flavour and fragrance. In pot culture it should be remembered that Mignonette does not transplant well; therefore, having sown, say, a dozen seeds in each of a batch of 48-or 32-sized pots, firmly filled with rich porous soil to which a little lime or mortar rubble has been added, the young plants must be thinned down to five, or even three, in each pot, as soon as they begin to grow freely. If small plants are wanted early, leave five in a pot; if larger specimens are wanted later, leave only three, or even only one. For winter and spring, sow in August and September and keep them as hardy as possible until it becomes necessary to put them under glass for the winter. A further sowing for succession may be made in January or February. Several strains of different tints are now at the command of cultivators of this favourite flower.

MIMULUS

Monkey Flower. Hardy perennial

This flower will grow in almost any soil, although a moist retentive loam and a shady situation are best adapted for it. There are many varieties, differing in height, and all are worth growing, both in pots and borders. If sown in February or March, and treated as greenhouse annuals, they will flower in the first year. It is easy to raise a large number of plants in a cold frame, and they make a rich display in borders and beds later in the year. Sowings in the open ground during summer will supply plants for blooming in the following season, but the most satisfactory course is to grow them as annuals, and at the end of the summer consign them to the waste heap. The Mimulus is quite hardy, and the most ordinary care will suffice for it. Water in plenty it must have, or the flowering period will be curtailed.

The well-known Musk is a Mimulus (_M. moschatus_), and is as easily grown from seed as other varieties. It makes a valuable pot plant.

MYOSOTIS

Forget-me-not. Perennials, hardy and half-hardy

AT one time an impression prevailed that all the varieties of Myosotis were semi-aquatic, and could only be grown satisfactorily in very damp shady places. And it is quite true that most of them bloom for a longer period in a moist than in a dry soil. Still, they all flower freely, and last a considerable time in any garden border.

The only half-hardy variety that need be referred to is Sutton’s Pot Myosotis, which is a delightful subject for flowering indoors at Christmas time; and as Forget-me-nots are everywhere welcome, the practice of growing plants in pots is rapidly increasing. Seed should be sown in a cold frame in June, and the seedlings can be potted on as required, taking care from the commencement to avoid crowding as a precaution against mildew, to which the plants are very liable. The strain referred to produces fine free-growing specimen plants, and a batch should always be in reserve for cutting. For table decoration in winter Forget-me-nots are very telling.

All the hardy varieties may be sown from May to July for a brilliant display in the following spring. The seed should be put into a prepared seed-bed under the shelter of a wall or hedge; and in autumn the plants must be transferred to blooming quarters at the earliest opportunity.

Myosotis make an extremely effective groundwork for spring bulbs, for which purpose _M. dissitiflora_ is the most valuable.

NASTURTIUM—_see_ TROPÆOLUM

NEMESIA STRUMOSA SUTTONI

Half-hardy annual

THIS beautiful South African annual is remarkable for its floriferous character, long duration of bloom, and diversity of colour. Since we introduced it to this country in 1888 it has attained great popularity as a pot plant for table decoration, and some of the most resplendent bedding effects in public parks and gardens have been secured with this flower.

For an early show of bloom sow in pots or pans in March under glass, using a compost consisting largely of good fibrous loam, with the addition of a small proportion of wood ashes. No more heat than necessary should be used, and when the seedlings are large enough to handle prick them off and gradually harden for planting out in May. Other sowings may be made in May and June, and at this period of the year the seed germinates most quickly in boxes placed in a cool shady spot out of doors. In early summer seed may also be sown in the open border, and by thinning to a distance of six or eight inches sturdy plants will be secured, which will remain in bloom until quite late in autumn.

For winter and early spring flowering in pots seed should be sown in August or September. There must be no attempt at forcing, or attenuated worthless plants will result. A further sowing may be made in January for blooming in the later spring months.

Like the seed of Verbena, Furze, and some other subjects, the germination of Nemesia under artificial conditions is somewhat capricious, but no difficulty will be experienced with open-air sowings.

NICOTIANA

Tobacco. Half-hardy annual

The delicious fragrance of the Tobacco plant, especially during the morning and evening, has made it a great favourite in the greenhouse and conservatory, as well as in beds and borders near frequented paths.

As a pot plant too, the Nicotiana is exceedingly useful, the large sweet-scented white, soft pink, and rich red coloured flowers being very attractive. A group of plants placed in the porch will, in the earlier and later hours of the day, as the door is opened, fill the house with their delightful perfume. Seed may be sown from January to June, and a continuance of bloom may thus be secured during nearly nine months of the year. Prick off the seedlings as soon as they are fit to handle, for if sown too thickly they are liable to damp off rapidly. Gradually harden off if required for planting out in May or June. In some places, more especially in the South of England, Tobacco seed sown on an open sunny border early in May will produce fine plants that will flower freely in August.

PANSY

Viola tricolor. Hardy perennial

The popularity of this flower has been greatly extended and the culture simplified since it became the practice to raise the required number of plants every year from seed. For all ordinary purposes the trouble of striking cuttings and keeping stocks in pots through the winter is mere waste of labour and pit-room. The Pansy is a little fastidious, but not severely so. It thrives in a cool climate, with partial shade in high summer, and in a rich, moist, sandy soil. Notwithstanding all this, the Pansy will grow almost anywhere and anyhow; but as fine flowers of this old favourite are highly prized, the plant should be treated with reasonable care to do justice to its great merits.

A thick sowing is very liable to damp off: therefore sow thinly, either in pots or boxes, in February and March. The thin sowing, moreover, renders it possible to take out the forward plants without disturbing the remainder. In due course transplant into pans or boxes of good soil, and place in some cool spot where the plants may gradually harden off. When they have become stocky, remove to beds or borders, with balls of earth attached to the roots. Should the surrounding soil become set by heavy rain or by watering, a slight stirring of the surface will prove beneficial.

Seed sown in the open ground during the summer months will readily germinate, and the seedlings need no attention beyond thinning to about six inches apart until they are ready for transferring to their proper positions, where they will produce a mass of bloom in the following spring.

The Pansy puts forth its buds very early in the year. Whether they are particularly tasty, or the scarcity of young vegetable growth gives them undue prominence, we know not, but certain it is that sparrows show a marked partiality for them. And having once acquired a taste for the buds, these impudent marauders will not leave them alone; they evidently regard Pansies as the perfection of a winter salad. Their depredations can be prevented by an application of water flavoured with quassia or paraffin oil, which must be repeated after rain.

PELARGONIUM

Greenhouse perennial

All kinds of Pelargonium may be raised from seed with the certainty of giving satisfaction if the work be well done. An amateur, who contributed to the production of symmetrical flowers in the Zonal section, found that under ordinary treatment Zonals began to bloom in one hundred days from the date of sowing the seed, and some of those that flowered earliest proved to be the finest. The cultivator will soon discover that one rule is important, and that is to sow seed saved from really good strains. The simplest greenhouse culture suffices to raise Pelargoniums from seed. Some growers sow in July or August; others in January or February. The summer sowing necessitates careful winter keeping, and the flowers appear earlier than those from spring-sown seed. But the spring sowing is the easier to manage, and is recommended to all beginners. Any light, sandy loam will serve for these plants, and it is well to flower the principal bulk of them in 48-and 32-sized pots, for if grown to a great size the date of flowering is deferred without any corresponding advantage.

PENTSTEMON

Hardy perennial

Penstemons when grown as half-hardy annuals are a valuable addition to beds and borders, where they produce a brilliant effect in summer. In borders it is not advisable to plant singly, but they should be employed in groups of not less than one dozen. It is also important to sow a strain consisting principally of scarlet and pink shades with white markings, as well as white flowers; under fair conditions there will be a profusion of richly coloured blooms on stately spikes about two feet high. Sow in heat during February or March and plant out in genial weather. It is not necessary to keep them after flowering has finished, although seedling Pentstemons on comparatively dry soil in favourable districts scarcely feel the winter. Seed may also be sown in June, in the manner usual with hardy perennials, and the plants will bloom in advance of those which are spring-sown.

PETUNIA

Half-hardy perennial

The Petunia affords another example of the immense strides accomplished in the art of seed-saving. Formerly the colours were few, and the blossoms comparatively insignificant. Now the single strains produce large flowers, beautiful in form, including self colours and others which are striped, blotched, and veined, in almost endless diversity. Some are plain-edged, others elegantly fringed. The double varieties also come so nearly true to their types that there is little necessity for keeping a stock through the winter. Plants raised from seed of the large-flowered strain embrace a wide range of resplendent colours, and the doubles are perfect rosettes, exquisitely finished in form and marking.

The only way of obtaining double seedlings is to save seed from the finest single blooms fertilised with pollen of good double flowers. Plants raised from such seed may be relied on to produce a fair proportion of double flowers of great beauty, and those which come single will be of the large-flowered type.

The dwarf varieties attain the height of five to eight inches only, and make admirable edging and bedding plants. The taller strains range from one to two feet, and are handsome subjects for border and shrubbery work. Both dwarf and tall sections are sufficiently brilliant and free-flowering to produce a beautiful display as pot plants in the greenhouse and conservatory.

For indoor decoration, the third week in January will be early enough to commence operations. Two parts of leaf-mould, one of loam, and one of sharp sand, make an excellent soil for them. Fill the pots or seed-pans within half an inch of the rim, and press the soil firmly down. Sow thinly on an even surface, and cover the seed with almost pure sand. Keep the pots or pans uniformly moist with a fine rose and a light hand, and in a temperature of about 60°. Greater heat will render the seedlings weak and straggling. From this condition it will take some skill and much time to redeem them; indeed, they may not produce a good display of flowers until the season is well-nigh over. Just as the seed is germinating is a critical time for Petunias, and a little extra watchfulness then will be fully repaid.

In February the sun has not sufficient power to do mischief, so that shading is generally unnecessary. An even temperature and freedom from draughts should insure seedlings strong enough to prick off by the end of that month. Put the plants into seed-pans about an inch apart, so that the first leaves just touch the soil, still using a light compost.

In April they should be ready for transferring to small 60-pots. Subsequently they must be potted on as growth demands, until they reach the 48-or even the 32-size. After re-potting place the plants in a sheltered part of the house or frame, where shade can, if necessary, be given until the roots are established. Frequent sprinklings of water, and a temperature of 60° or 65°, will give them a vigorous start. The lights ought to be put down in good time in the evening, but this must be done with judgment, or the plants will lose their healthy colour and assume a yellowish tinge. Insufficient drainage has a precisely similar effect. In about ten days air may be given more freely, and then no suitable opportunity of exposure should be lost.

In raising Petunias for bedding, the same conditions are applicable; but as it is useless to put them into the open ground until the weather is warm and settled, the sowing need not be made until the end of February or the beginning of March. And for bedding there is no occasion to put the plants into larger pots than the 60-size. It will be necessary to give these seedlings shade in their young state, after they have been pricked off or potted.

The beds or borders intended for Petunias will be better without recent manure, for this tends to the excessive production of foliage and defers the flowering until late in the season. Do not be tempted by the first sunny day to put them out, but wait for settled weather. A cutting east wind, such as we sometimes have in May, will ruin them irretrievably. Each plant of the tall class will occupy a space of two feet, and the dwarfs may be one foot apart.

In potting Petunias, those which are weakly among the singles will probably produce the most valued colours, and from seed sown for doubles it may be accepted as a rule that from the feebler seedlings the finest rosette-shaped flowers may be expected.

All Petunias are impatient of being pot-bound, and this applies especially to the double varieties. They will, if treated generously, do ample justice to the 8-or even the 10-inch size. The growth should not be hurried at any stage, and if the foliage has a dark, healthy, green colour, free from blight, there will be magnificent flowers four or five inches across. The final shift should be into a sound compost, consisting, if possible, of good loam and leaf-mould in equal parts, with sufficient sand added to insure drainage. About a fortnight later commence giving weak manure water once a week instead of the ordinary watering, and as the buds appear it may be increased in strength, and be administered twice a week until the flowers expand.

Petunias are accommodating in their growth, and may be trained into various forms. The pyramid and fan-shape are most common, and the least objectionable. We confess, however, to a feeling of antipathy to fanciful shapes in plants, no matter what they may be. It is a necessity of our artificial conditions of culture that many of them should be trained and tied to produce shapely specimens, but the more nearly the gardener’s art approaches Nature, the greater pleasure we derive from his labours.

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 massing 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 space between the plants to save pricking 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 sunshine. Phloxes should not be coddled; the best results are always obtained from sturdy 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 space of about two feet each way is required for each plant of the large-flowered class, 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 shift being into pots of the 48-size. When grown under glass, 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 prick 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 furnishing 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. Prick 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 passing 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 association 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 Shirley Poppies is alone sufficient to create a reputation for the entire class, 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.
