Gordonia, including Polyspora. Ternstrcemiacece. 

 Propagated by seeds or layers. 



Gorse. See Ulex. 



Goumi. See Elaeagnus. 



Gourds (Cucurbita Pepo, Lagenaria, etc.). Cucurbitaceae. 

 Seeds, after the weather is settled and ground is warm. 



Grammanthes. Crassulacca >.. 



Seeds, sown in spring in a warm house. 



Granadilla (Passijlora edulis, etc.). Passiflorece. 



Propagated by seeds, or, less easily, by cuttings. 



Grape (Vitis, several species). Vitacece. 



Grape seedlings are very easily grown. If the ground is 

 fit and there is no danger from vermin, the seeds may be 

 sown in the fall, but they are usually stratified and sown in 

 spring. They come readily if sown out-doors, but some pre- 

 fer to force them under glass with a mild bottom heat. 

 Seedlings do not " come true," and they are therefore grown 

 only for the purpose of obtaining new sorts. 



The grape is very readily multiplied by layers, either of 

 the ripe or green wood. The ripe wood or canes may be 

 layered either in fall or spring, but spring is usually chosen. 

 The cane is simply covered up two or three inches deep, and 

 nearly every bud will produce a plant. In August or Sep- 

 tember the layer should be lifted and cut up into plants. 

 Better plants are obtained if only the strongest canes are 

 used and only a part of the buds on each are allowed to 

 grow. The cane is usually cut back to four or five buds, or 

 if very strong plants are desired only one bud is left on each 

 layer. Canes of the previous year, those recently matured, 

 are preferred, although wood two or three years old may be 

 used, but in this case it is usually necessary to cut or other- 

 wise wound the joint in order to induce the formation of 

 roots. Vines or stools grown for the production of layers 

 should be cut back severely in fall or winter, to induce a vig- 

 orous growth of canes the following season. These canes 

 are then layered the succeeding fall or spring. Only a part of 

 the canes are layered from any 'stool, a part being allowed to 

 grow for cutting back the next fall in order to get another 

 crop of canes. In some varieties which do not strike readily 

 . from cuttings, layering is considerably practiced by nursery- 

 men. The Delaware is often grown in this way. Extra 



; strong layers can be secured by layering in pots. A large
