==Gaillardia==

==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 pricking 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 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 deg. to 70 deg. 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==

==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.
