Gardenia (garde-ma, after Dr. Garden. Ord. Rubiaceae). 

 Producing white, strongly scented flowers of neat shape and con- 

 venient size, Gardenia florida is a popular plant. It thrives in a 

 warm, moist atmosphere, and does best when planted out; it may, 

 however, be grown in pots, 6-in. and /-in. being suitable sizes. 

 A compost of loam 3 parts, leaf mould and dried cow manure i 

 part each, with sand, suits it. A temperature of 60 to 70 should 

 be provided in winter. Propagation is by cuttings inserted under 

 a bell-glass in bottom heat in spring. There are several varieties of 

 G. florida, of which the double white is the best known. Variegata 

 has yellow-margined leaves. Others are Fortuneana and radicans.

Garrya (gar-rya, after Mr. Garry. Ord. Cornaceae). The one 

 species grown to any extent, elliptica, is a hardy evergreen shrub, 

 producing yellow flowers in spring. It is not particular as to soil. 

 Propagation is by cuttings under a bell-glass in September. See 

 the Botanical Register, t. 1686. 



Gaultheria, Wintergreen (Gaulthe-ria, after Dr. Gaulther. Ord. 

 Ericaceae). One or two members of this small genus are esteemed 

 for the rock garden. They are small evergreen shrubs that thrive 

 in peaty soil and are propagated by layers. Procumbens, the Part- 

 ridge Berry, has white flowers in July. Shallon has white flowers in 

 spring. See the Botanical Magazine, t. 2843. 



Gazania (gaza-nia, from gaza, richness, alluding to the brilliant 

 flowers. Ord. Compositae). Half-hardy plants suitable for the 

 flower garden in summer. Splendens is the most commonly grown, 

 and it' bears orange flowers. Ordinary friable soil suits it, and it 

 may be propagated by cuttings under a bell-glass in summer. 



Genista, Broom (genis-ta, Virgil's name. Ord. Leguminosae) . 

 These are allied to Cytisus. They are easily grown, thriving in 

 most soils, and propagated by cuttings in a frame. Hispanica, the 

 Spanish Broom; tinctoria, the Dyer's Greenweed, and its varieties; 

 .and virgata are the principal sorts. See Broom and Cytisus. 



Gentiana, Gentian (gentia-na, after Gentius, King of Illyria. Ord.

 their brilliant blue flowers, which are unexcelled for richness of 

 colour. The Alpine species like a peaty soil. They may be raised 

 from seed in a greenhouse in spring, or divided in spring. There are 

 no choicer flowers for rockwork. " Gentian-blue " has become a 

 popular expression to indicate brilliance. The following are the 

 -principal Gentians:
