The Culture Of Vegetables And Flowers From Seeds And Roots Part 37

In this case the roots will not be quite so regular as those which have been wholly grown in water. Perhaps we need scarcely say that it is possible to utilise this flower in many other ways--such, for instance, as in decorating epergnes, gla.s.s globes, and fancy vases. They may also be made to float on a small fountain or aquarium; indeed, it is surprising to what varied and effective purposes a little ingenuity will adapt them.

==Culture in Open Ground.==--For this purpose the Narcissus will always command attention for its graceful appearance; and this observation applies with as much force to the Polyanthus section, when thus used, as to the varieties which are specially recognised as Garden Narcissus. The latter cla.s.s includes many old favourites, among which is the Pheasant's Eye--one of the most exquisite flowers grown in our gardens.

The Narcissus is often used for bedding with superb effect. The graceful habit, which is one of its princ.i.p.al charms, is very striking in large ma.s.ses, and its elegant appearance in the positions for which it is naturally suited cannot fail to arrest attention. Beneath trees, by the side of a shady walk, in front of shrubberies, or in the mixed border, the Narcissus is thoroughly at home.

If possible, choose a position where the bulbs need not be disturbed for several years, and plant them early. When the spot they are to occupy happens to be full, pot the bulbs until the ground is vacant, and in due time turn them out. A southern or western aspect is desirable, but the nature of the soil is comparatively unimportant, provided it is dry when the bulbs are in their resting state. In sour land or in stagnant water they will certainly rot, but a touch of sea spray will not injure them.

If the soil needs enriching, there is no better material than decayed cow-manure, which may be incorporated as the work goes on, or it can be applied as a top-dressing. Those which are evidently weak may be a.s.sisted with a few doses of manure water, not too strong.

In planting groups, put the smaller bulbs four or five inches, and the larger sorts from six to nine inches apart; depth, six to nine inches, according to size. Where exposed to a strong wind, it may be necessary to give the flowers some kind of support to save them from injury.

The Double and Single Daffodils are now in marked public favour and their bright colours make them extremely useful for beds and borders.

For planting under and among trees they are invaluable, and a sufficient number should always be put in to produce an immediate effect. They thrive in damp, shady spots, and every three or four years it will be necessary to divide and replant them.

==The Chinese Sacred Lily== (=Narcissus Tazetta=).--The popular name of this flower is misleading. It is not a Lily, but a Narcissus of the Polyanthus type, and, like others of the same cla.s.s, the bulbs may be successfully grown in soil or in water. But =Narcissus Tazetta= has proved to be singularly beautiful in water, and the management of it entails very little trouble. A wide bowl of j.a.panese pattern is appropriate for the purpose, and to obtain the best effect the bowl should be partially filled with a number of plain or ornamental stones, with a few pieces of charcoal to keep the water sweet. On the top, and so that they will be held by the stones, place one or more bulbs: pour in water until it covers the base of the bulbs. Store in a dark cool cellar until the roots have started and the leaves begin to appear; then remove to the room where the ornament is wanted. Occasionally the water must be replenished. The development of the flower-heads is surprisingly rapid, and a large bulb generally produces several cl.u.s.ters of sweetly scented flowers. But if the bulbs are forced too quickly the blossoms are sometimes crippled.

==ORNITHOGALUM==

==Star of Bethlehem==

During the month of June =O. arabic.u.m= produces heads of pure white fragrant flowers, each having a green centre. The roots are large and fleshy, and should be planted in the autumn six inches deep. A sheltered position, such as under a south wall, is desirable for them, and some protection in the form of dry litter, or a heap of light manure, will be necessary to carry the roots safely through severe winter weather. The bulbs are frequently potted for indoor decoration. Another variety, =O.

umbellatum=, with pure white starry flowers, makes an attractive show in May, and is valuable for naturalising in clumps or ma.s.ses in the border.

==OXALIS==

These frame plants are suitable for the cool greenhouse or for forcing, and they are adapted also for the open border in peculiarly favourable districts. They are particularly neat and cheerful, flowering abundantly, and requiring only the most ordinary treatment of frame plants. In winter they should be kept dry. The 48-sized pot is suitable, and about five bulbs may be planted in each, using light soil freely mixed with sand.

==RANUNCULUS==

To maintain a collection of named Ranunculuses demands skill and patience, but a few of the most brilliant self-coloured, spotted and striped varieties may be easily grown, if a cool, deep, rich, moist soil can be provided for them. The best soil for the Ranunculus is a loam or clay in which the common field b.u.t.tercup grows freely and plentifully.

The situation should be open, the bed well pulverised, and the soil effectively drained, both to promote a vigorous growth and, as far as possible, to save the plants from injury by wireworms, leather-jackets, and other ground vermin. Elaborate modes of manuring, such as mixing several sorts of manure together in mystical proportions, are altogether unnecessary, but a good dressing of rotten manure and leaf-mould should be dug in before planting, and if the soil is particularly heavy, sharp sand must be added. The roots may be planted in November and December in gardens where vegetation does not usually suffer from damp in winter; but where there is any reason to apprehend danger from damp, the planting should be deferred until February, and should be completed within the first twenty days of that month, if weather permit. Prepare a fine surface to plant on, and draw drills six inches apart and two inches deep, and place the tubers, claws downwards, in the drills, four inches apart, covering them with sifted soil before drawing the earth back to the drill. Rake the bed smooth, and the planting is completed.

To keep free from weeds, and to give plentiful supplies of water in dry weather, are the two princ.i.p.al features of the summer cultivation. When the flowers are past, and the leaves begin to fade, take up the roots, dry them in a cool place, and store in peat or cocoa-nut fibre.

==Turban Ranunculus.==--This cla.s.s is remarkably handsome, of hardier const.i.tution and freer growth than the edged and spotted varieties. For the production of ma.s.ses of colour, and to form showy clumps in the borders, the Turban varieties are of the utmost value. They require a good loam, well manured, and the general treatment advised for the named varieties; but as they are not so delicate they will thrive under less congenial conditions.

==SCILLA==

The Blue Squill may be grown in exactly the same manner as the Roman Hyacinth for indoor decoration, and it makes a charming companion to that flower. It is perfectly hardy, and for its deep, lovely blue should be largely grown in the open border, where it appears to especial advantage in conjunction with Snowdrops. It is also valuable for filling small beds, and for making marginal lines in the geometric garden.

The =Scilla praec.o.x=, or =sibirica=, thrives on the mountains of North Italy, where ma.s.ses of it may be seen growing close to the snow, and in this country it withstands wind and rain which would be the ruin of many another flower. Still we like to see it in a sheltered border, where it has a fair chance of displaying its beauty without much risk of injury.

In such a position it will flower in February, and in the bleakest quarter it will open in March. It is not at all fastidious as to soil, but when planted will give no further trouble until the foliage withers, and it is time to lift the bulbs to make way for other occupants. If convenient, the roots may remain for years in one spot.

The =Scilla campanulata= deserves more attention than it has. .h.i.therto received. After almost all other spring-flowering bulbs are over, it makes a beautiful display, which lasts until nearly the end of May. It somewhat resembles the wild Blue-bell, but is much larger than that woodland flower.

==SNOWDROP==

Snowdrops are among the hardiest flowers known to our gardens, and are invaluable for their welcome snow-white bells in the earliest days of the opening spring. They should be planted in clumps, and left alone for years. The double-flowering variety is exquisitely beautiful: we might, indeed, speak of it as a bit of floral jewellery. The flowers are bell-shaped, closely packed with petals, like so many microscopic petticoats arranged for the 'tiring' of a fairy: they are snow-white and sometimes delicately tipped with light green. This variety is as hardy as the single, and the best for growing in baskets and pots. When employed in lines the planting ought to be very close together, and the line should be composed of several rows, making, in fact, a broad band.

Such a ribbon when backed with =Scilla sibirica= is very beautiful. The best way of displaying the Snowdrop alone is in large groups densely crowded together. The effect is much more telling than when the same number of bulbs is spread over a larger area. Put the roots in drills, two inches deep, and if possible in a spot where they need not be disturbed for two or three years. Snowdrops may be grown in pots, and be gently forced for Christmas. But unless wanted very early, it will answer to lift clumps from the border in November and pot them.

==SPARAXIS==

See instructions under Ixia at page 338.

==TIGRIDIA, or FERRARIA==

The short-lived blossoms of the Tiger Flower are most gorgeously painted, and differ from everything else of the great family of Irids to which they belong. Much finer flowers are produced in the border than when grown in pots, and they present great variety, scarcely any two amongst hundreds showing flowers exactly alike. The usual time of planting outdoors is March or April, at a depth of three or four inches, and the flowers appear in June. Sandy loam and peaty soils are especially suitable. Although Tigridias are not quite hardy they will on a dry border pa.s.s the winter securely beneath a protection of litter.

But where the soil is damp it is safer to lift them in October and store in the same manner as Gladioli. A bed of Tigridias makes an agreeable ornament in front of the window of a breakfast-room, as the flowers are in a brilliant state in the early hours of the day.

==TRITELEIA UNIFLORA==

This little gem belongs to the spring garden, and should be the companion of the Dog's-tooth Violet, the Crocus, and the Snowdrop. It will grow in any soil, and will produce an abundance of its violet-tinted white flowers, which, when handled, emit a faint odour of garlic. As a pot plant for the Alpine house it is first-rate. In the open, plant in October two inches deep.

==TRITONIA==

Tritonias are more showy than the Ixia or Sparaxis, but belong to the same group of South African Irids, and require the same treatment. They may be planted out in April, if prepared for that mode of cultivation by putting them in small pots in November or December. It is not advisable to tie them to sticks, for they are more elegant when allowed to fall over the edge of the pots, and suggest the 'negligence of Nature.'

==TROPaeOLUM==

=T. tuberosum.=--A few of the tuberous-rooted Tropaeolums are hardy, but it is not wise to leave them in the ground, for damp may destroy them, if they are proof against frost. They are all graceful trailing plants, adapted for covering wire trellises, and may be flowered at any season if required, though their natural season is the summer. The compost in which they thrive best is a light rich loam, containing a large proportion of sand. The stems are usually trained on wires, but they may be allowed to fall down from a pot or basket with excellent effect, to form a most attractive tracery of leaf.a.ge dotted with dazzling flowers.

The sunniest part of the greenhouse should be devoted to the Tropaeolums, and special care should be taken in potting them to secure ample drainage.

=T. speciosum.=--This showy variety is quite hardy, and is largely grown in Scotland where it may frequently be seen on cottage walls. The roots may be planted in either spring or autumn, and a moist, somewhat shaded position best suits the plant.

==TUBEROSE==

==Polianthes tuberosa==

This bulb is extensively grown in the South of France for the delicious perfume obtainable from its numerous pure white flowers. In this country it is widely known, but considering the beauty and exceeding fragrance of the blossoms it is astonishing that a greater number are not planted every season. Perhaps the fact that the bulbs are valueless after the first year may in a measure account for the comparatively limited culture. They are easily flowered as pot plants in a mixture of loam and leaf-mould, plunged in a bottom heat ranging between 60 and 70. The growth is rather tall, and unless kept near the gla.s.s the stems become unsightly in length.

==TULIP==

==Culture in Pots.==--When grown in pots, Tulips are treated in precisely the same manner as the Hyacinth, but several bulbs, according to their size and the purpose they are intended for, are placed in a pot. When required to fill epergnes and baskets, and other elegant receptacles, it is a good plan to grow them in shallow boxes, as recommended for Crocuses, and transfer them when in flower to the vases and baskets.

This mode of procedure insures exact.i.tude of height and colouring, whereas, when the bulbs are grown from the first in the ornamental vessels, they may not flower with sufficient uniformity to produce a satisfactory display. In common with the Hyacinth and Crocus, Tulips may be taken out of the soil in which they have been grown, and after washing the roots clean, they can be inserted in gla.s.ses for decorating an apartment. Early Tulips are often employed in this way to light up festive gatherings at Christmas and the early months of the year. But the pot culture of Tulips need not be restricted to the early varieties.

The Darwin and May-flowering cla.s.ses are also admirable when grown in this way, but it is important they should not be hurried into bloom. If placed in moderate heat and allowed ample time to develop, beautiful long-stemmed flowers may be had in March which will make a charming decoration for the drawing-room or the dinner-table.

==Culture in Moss-fibre.==--No bulb excels the Tulip in adaptability for bowl culture, given the treatment suggested for Narcissi and Daffodils on page 345, and particularly with respect to moisture.

==Culture in the Open Ground.==--For general usefulness the early Tulips are the most valuable of all, because of their peculiarly accommodating nature, their many and brilliant colours, and their suitability for the formation of rich ma.s.ses in the flower garden. Any good soil will suit them, and they may be planted in quant.i.ties under trees if the position enjoys some amount of sunshine, because they will have finished their growth before the leaf.a.ge of the trees shades them injuriously. If it is necessary to prepare or improve the soil for them, the aim should be to render it rich and sandy, and sufficiently drained to avoid a boggy character in winter. Plant in October or November, four or five inches deep, and six inches apart. The roots require no water and no supports, and may all be taken up and stored away in good time for the usual summer display of bedding plants. For geometric planting it is important to select the varieties with care, but a most interesting border may be made by planting clumps of all the best sorts of the several cla.s.ses. The result will be a long-continued and splendid display, beginning with the 'Van Thols' (which are as hardy as any), following with the early cla.s.s in almost endless variety, and finishing with the n.o.ble Darwin and May-flowering sections. The last named include a very large number of extremely handsome flowers, and their lasting beauty is of especial value at a season of the year when spring blooms are over and summer plants have scarcely begun to make a show.
