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.
