318 THE NURSERY-MANUAL 



Geranium. Geraniacece. 



Mostly increased by seeds and divisions. The true geraniums 

 are mostly outdoor perennials ; for the conservatory plants known 

 as geraniums, see Pelargonium. 



Gerardia. Scrophulariaceae. 



Propagated, but often with difficulty, by seeds, sown in the 

 open air or in a frame or coolhouse. Many of the species are 

 partially parasitic on roots. 



Gerbera. Compositoe. 



Propagated by seeds, and by cuttings of side shoots. Seeds give 

 good results, as a perennial. 



Gesneria. Gesneriaceoe. 



Propagated by seeds, cuttings of the shoots and leaves, and by 

 offsets of the tubers. Handled in essentially the same way as 

 sinningia, which see. See Gesneriacece. 



Gesneriaceae. Gesneriads. 



Propagation is effected by cuttings of the young shoots when 

 about 2 or 3 inches long placed in a close moist propagating-frame, 

 using clean sharp sand or sand and peat mixed, in a temperature 

 of 70 to 75. Or by leaf -cuttings, using mature leaves. Prop- 

 agation by seeds is the most common method for most of the 

 genera. They should be sown in January or February in small 

 pans of finely sifted soil, composed of leaf-mold, loam and sand in 

 about equal parts. Seeds should be sown very thinly, covered 

 very lightly, carefully watered, placed in a temperature of 65 to 

 70 and kept shaded. The seedlings damp readily and should be 

 pricked into small pans of fresh soil as soon as they are large enough 

 to handle. 



Geum. Rosacece. 



Propagated by division and by seed. 



Gherkin (Cucumis Angurid). Cucurbitaceos. 

 Easily grown from seeds, as for cucumber. 



Gilia, including Fenzlia. Polemoniaceae. 



Seeds may be sown in spring in the open ground or frame, 

 usually in the open.
