Glaux Maritima (Sea Milkweed).—­A pretty little hardy trailing plant bearing flesh-coloured flowers in June and July.  It grows in sandy loam, and is raised from seed sown in spring.  Height, 3 in.

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.
