==Half-hardy perennial==

All the Gaillardias are most conveniently grown as annuals from seed.

The plants remain in bloom for a long period, and for their gorgeous colouring the flowers are as highly prized for arranging in bowls and vases as for garden decoration. The best month in which to sow seed is March, and the plants will then be ready for putting out in May. Any good compost will answer, and only a moderate temperature is necessary to bring up the seedlings. The usual course of procedure in p.r.i.c.king off must be adopted to keep them short and stout.

==GERANIUM==

==Pelargonium. Half-hardy perennial==

Geraniums of all kinds are most valuable if treated as annuals. In their seedling state the plants are peculiarly robust and charmingly fresh in leaf.a.ge 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-cla.s.s 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. p.r.i.c.k 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==

==Naegelia. 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 p.r.i.c.ked 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-cla.s.s 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.
