Globe Amaranthus (Gomphrena).--This tender annual is well known for
its clover-like heads of everlasting flowers. It will grow in any rich
soil, but to produce really fine plants, much attention must be given
to shifting, watering, etc. Increased by seed in the same manner as
other tender annuals. Blooms in July. Height, 1 ft.
Globe Flower.--See "Trollius."
Globe Thistle.--See "Echinops."
Globularia Trichosantha.--A pretty dwarf perennial rock-plant bearing
pale blue flowers in May and June. It is hardy, thrives in light,
sandy soil, and is increased by either seeds or cuttings planted in
sand. Height, 6 in. The greenhouse varieties of Globularia grow best
in loam and peat.
Glory of the Snow.--See "Chionodoxa."
Gloxinias.--A very ornamental family of tuberous-rooted hothouse
plants. They are of two classes, the drooping and the erect. Pot at
any time during January and March in a mixture of equal quantities of
loam, peat, and sand, with the addition of a little vegetable soil,
and place in a warm (60 degrees), moist temperature, where they can be
favoured with a little shade. In summer supply the roots plentifully
with water, but give them very little in winter. Overhead watering
is likely to rot the leaves and flowers. G. Maculata is increased by
division. The leaves of most of the others, if taken off close to the
stem, and planted, will soon make young plants. They may be raised
from seed sown from March to July in a hothouse or frame having a
temperature of 65 to 75 degrees. They flower in June, and on into
September. Height, 6 in. to 1 ft.
Glycine.--See "Wistaria" and "Apios."
Gnaphalium (Edelweiss).--Hardy everlasting flowers, which are
covered with a woolly substance. They may be grown in any light, rich
soil. The shrubby and herbaceous kinds may be increased by cuttings
or division. The annuals are easily raised from seed. They flower in
July. Height, 1 ft.
Goat's Rue.--See "Galega."
Godetia.--Very pretty hardy annuals, that may be grown in any garden
soil. Sow in the autumn for early flowering, or in spring for later
blooms. July is their ordinary season of coming into flower. Height,
1-1/2 ft. to 2 ft.
Golden Feather.--Hardy annual foliage plants. They are not particular
as to soil, and are easily raised from seed sown early in spring. They
bloom in July. Height, 1 ft.
Golden Rod.--See "Solidago."
