Part 19

Furze.--Enjoys a sandy soil. Increased by cuttings taken in spring or autumn and placed in a shady border under hand-glasses. It is of evergreen habit, and forms a dense and highly ornamental hedge. (See also "Ulex.")

Gages.--The cultivation of Gages is similar to that of Plums. In the open they may be grown as dwarfs or pyramids, and in orchard-houses as gridirons, cordons, or in pots. The chief points to observe are to thin the branches in order to admit plenty of light into the middle of the tree, thus inducing the production of a plentiful supply of fruit spurs, and to occasionally lift and root-prune the tree if growing too strong. Among the choicest sorts are: Bonne Bouche (producing its fruit at the end of August), Coe's Golden Drop (end of September), Old Green Gage (August), Guthrie's Late Green Gage (September), M'Laughlin's Gage (end of August), Oullin's Golden Gage (end of August), and Reine Claude de Bavay (beginning of October).

Gaillardia (Blanket Flower).--Very ornamental flowers, which will grow in any common soil, but thrive most in a light, rich one. Seeds of the annual kinds are sown in the spring. The perennials are increased by dividing the roots. Bloom in July. Height, 1 ft. to 2 ft.

Galanthus.--See "Snowdrops."

Galax Aphylla (Wand Plant).--The Heart-shaped Galax is a charming little plant for rock-work. It is perennial, and does not lose the old leaves till the new ones appear. A rich, light mould is required for its growth, and its situation should be a somewhat shady one. Its flowers are borne in July and August, on stalks 1 ft. or more high. The plant may be increased by taking up a strong clump, shaking it apart, and transplanting at once. (See also "Shortia.")

Galega (Goats Rue).--Ornamental hardy perennials, requiring plenty of room. They are readily increased by seed or division of the root, and flower in July. Height, 3 ft. to 4 ft.

Galium.--This hardy herbaceous plant blooms in July. It will grow in any soil, and can be increased by division of the root. Height, 1 ft.

Gardenias.--Plant in a hothouse in fibrous peat mixed with a large proportion of sand. Give plenty of heat and moisture during growth, with a thin shade to keep off the sun's midday rays. Lower the temperature as soon as growth is completed, and in the middle of summer stand the plants out in the open for a week or two for the wood to ripen. Height, 3 ft.

Garlic.--Plant small cloves from February to April in rows 9 in. apart and 6 in. from each other in the row. Lift them when the leaves die down, dry them in the sunshine, and store in an airy, cool shed.

Garrya Elliptica.--A hardy evergreen shrub, which is very suitable in its early stages for pot-culture. A light, loamy soil is what it likes. Cuttings taken in August and placed in sand under a hand-glass will strike freely, but it is most readily increased by layers. In October it bears graceful yellowish-green tassels of flowers from the ends of its shoots. Height, 6 ft.

Gasteria Verrucosa.--This plant grows best in pots of turfy loam and leaf-mould, to which has been added a little old mortar. Good drainage is essential. Water freely in summer, and keep just moist in winter. Keep the foliage clean by sponging. Give plenty of light, and during warm weather turn the plants out of doors.

Gastrolobium.--Elegant evergreen shrubs which flower in April and May. They are most suitable for adorning the greenhouse, and grow best in a soil of loamy peat and sand. Cuttings of half-ripened wood planted under glass will take root. Height, 2 ft.

Gaultheria.--Dwarf, creeping evergreen shrubs, having dark foliage and producing white flowers in May, June, or July. They require to be grown in peat, and are increased by layers. G. Procumbens is suitable for rockeries, as it only grows to the height of 6 in. G. Shallon attains the height of 2 ft.

Gaura Lindheimeri.--This free-flowering, hardy, herbaceous plant will thrive in any light, rich soil. It bears elegant spikes of white flowers from May onwards, followed by red bracts in September, and is readily propagated by seeds. Height, 4 ft.

Gazania Splendens.--A showy greenhouse plant. It may be planted in the open in warm positions, but will require protecting in winter. Grow it in peat and loam. Cuttings will strike if placed in sand under glass. It flowers in July. Height, 1 ft.

Genethyllis.--Greenhouse evergreen shrubs which thrive best in sandy loam and peat. Cuttings of the young wood planted in the same soil and plunged in heat will take root. Their flowering season is in August. Height, 3 ft.

Genista (Broom).--G. Canariense is an exceedingly ornamental and free-flowering greenhouse shrub. It should be planted in a mixture of loam, peat, and sand. Young cuttings inserted in sand under a glass take root readily. It blooms in June. Height, 2 ft. Hardy species of Genista may be placed in the front of shrubberies. They are increased by seeds or by layers.

Gentians.--The herbaceous kinds do best in a light, rich soil, such as loam and peat mixed with vegetable mould. The annuals are raised from seed sown as soon as it is ripe; if left till spring before it is sown it will probably not come up till the second year. The perennials are increased by dividing the roots. Both of the latter kinds do best in a dry, sandy soil. Gentiana Acaulis, or Gentianella, is very suitable for edgings, or for rock-work; it is an evergreen creeper, and bears large trumpet-shaped flowers of rich ultramarine blue. All the Gentians need plenty of free air, and some of them moisture at the roots. Bloom in July. Height, 4 in. to 2 ft.

Geranium Argentium(Silvery Crane's-Bill).--This hardy perennial alpine is very effective on rock-work, especially in front of dark stones; but provision must be made for its long tap roots. A rich, deep loam suits it well. Its seeds germinate freely when sown in peat and sand. Flowers are borne from May to July. Height, 6 in.

Geraniums.--Take cuttings in July or August, and let them he to partially dry for twenty-four hours before planting. When rooted pot them off in 60's, and keep them under glass during the winter at a temperature of 55 degrees. If the cuttings are taken in September put three or four slips in a 48-size pot. In the spring they should be re-potted singly and hardened off as early as possible. A suitable soil for them is made by mixing two parts of good turfy loam, one of leaf-mould, one of well-decomposed cow-dung, and a good proportion of silver sand. Bone dust is an excellent addition to the soil. Old plants stripped of their leaves may be packed in sand during the winter, and re-potted in spring.

Gerardia.--These hardy perennials form pyramidal bushes bearing Pentstemon-like flowers, thickly set and varying in colour from light pink to dark purple. A peat soil suits them best. They may be propagated by cuttings placed under glass, but are best grown from seed. July is their flowering season. Height, 1 ft. to 2 ft.

German Seeds.--These require to be sown in a cold frame in seed-pans, in the greenhouse, or under a handglass, in good, rich compost, composed of old turf, leaf-mould, some well-rotted manure, and silver sand. The seeds should be sown thinly and watered sparingly. Sow early in April, and transplant in the middle or end of May in rich soil. Water occasionally with weak liquid manure.

Gesneria.--Handsome greenhouse perennials. They thrive in any light, rich soil. Cuttings will strike readily either in sand or soil if placed under glass in heat. They may also be raised from seed sown in a temperature of 75 degrees in March or April. They flower in October. Height, 18 in.

Geum.--Very handsome hardy perennials. They grow well in any light, rich, loamy soil, and may be increased either by seeds or by dividing the roots. G. Coccineum is extremely pretty. Flower in July. Height, 18 in.

Gherkins.--Sow the seed the first week in April in small pots, and cover it lightly with fine soil. Plunge the pots in a hotbed covered with a frame. When grown to nice little plants, remove them to a cold frame to harden, and plant them out on a warm border towards the end of May. When the fruit begins to form, give liquid manure twice a week. For pickling they must be cut while small.

Gilia.--Extremely pretty and free-flowering hardy annuals, deserving of a place in every garden. They are very suitable for small beds. They should be sown in the open early in spring. G. Tricolour may be sown in autumn. Bloom in July. Height, 1 ft.

Gillenia Trifoliata.--The Three-Leaved Gillenia is a hardy herbaceous perennial which is very useful as a cut flower for the decoration of vases, etc. It should be grown in large clumps, delights in a deep, moist soil and partial shade, and may be propagated by dividing the roots early in spring. It lasts in bloom from June to August. Height, 1 ft.

Gladiolus.--Dig the ground out to a depth of 1 ft. or 15 in.; put in a layer of leaf-mould or rotted manure, and then 4 or 5 in. of earth mixed with sand; insert the bulbs (6 in. from the surface and 9 in. apart), cover them with 1 in. of sand, and fill up with earth. In frosty weather cover with a thick layer of litter. Give plenty of water when they begin to throw up their flower-stems. They may be planted at any time between December and the end of March. If planted late in the season, a depth of 3 or 4 in. is enough. The roots must be kept dry in winter. They are increased by off-sets, taken when the bulbs are removed from the ground after the leaves have turned yellow. These should be planted at once in well-drained earth. If early flowers are required, plant the old bulbs in pots (three to six bulbs being placed in a 5-in. pot) any time between December and March. Give them frame culture up to the second week in May, when they may be transferred to the border. The flowers are invaluable for vase decoration.
