ve plenty of water in
summer, a moderate amount at other seasons. Ripened cuttings may be
rooted in sand, under a glass. Young plants may also be obtained from
seed. They bloom in June. Their common height is from 3 to 4 ft.,
but G. Robusta attains a great height. Grevilleas will grow well in
windows facing south.

Griselinia Littoralis.--A dwarf-growing, light-coloured evergreen
shrub, which will thrive near the sea. It requires a light, dry soil,
and may be increased by cuttings.

Guelder Rose.--_See_ "Viburnum."

Guernsey Lily (_Nerine Sarniense_).--Soil, strong, rich loam with
sand, well drained. Plant the bulbs deeply in a warm, sheltered
position, and let them remain undisturbed year by year. Keep the beds
dry in winter, and protect the roots from frost. They also make good
indoor plants, potted in moss or cocoa-nut fibre in September, or they
may be grown in vases of water.

Gumming of Trees.--Scrape the gum off, wash the place thoroughly with
clear water, and apply a compost of horse-dung, clay, and tar.

Gunnera Manicata (_Chilian Rhubarb_).--This hardy plant bears large
leaves on stout foot-stalks, and is very ornamental in the backs of
borders, etc. Planted in a rich, moist soil, it will flower in August.
It can be propagated by division. Height, 6 ft.

Gunnera Scabra.--Has gigantic leaves, 4 to 5 ft. in diameter, on
petioles 3 to 6 ft. in length. It prefers a moist, shady position, and
bears division. Makes a fine addition to a sub-tropical garden, where
it will flower in August. Height, 6 ft.

Gynerium (_Pampas Grass_).--This unquestionably is the grandest of all
grasses, and is sufficiently hardy to endure most of our winters. It
is, however, desirable to give it some protection. It requires a deep,
rich, alluvial soil, with plenty of room and a good supply of water.
Plants may be raised from seed sown thinly in pots during February or
March, barely covering it with very fine soil, and keeping the surface
damp. Plant out at end of May. They will flower when three or four
years old. The old leaves should be allowed to remain on till the
new ones appear, as they afford protection to the plant. It may be
increased by division of the root. Height, 7 ft.

Gypsophila.--Of value for table bouquets, etc. They will grow in any
soil, but prefer a chalky one. The herbaceous kinds are increased by
cuttings; the annuals are sown in the open either in autumn or spring.
They bloom during July and August. Height
