THE NURSERY LIST. 209 



Jacquinia. Myrsinece. 



Cuttings of ripened shoots, usually made in summer, 

 placed in sand, in a moist bottom heat. 



Jalapa. See Mirabilis. 

 Jambosa. See Myrtus. 

 Jasione (Sheep's Scabious). Campanulacea:. 



Seeds, sown in spring or fall, usually in the open. The 

 perennials may be divided. 



Jasminum (Jasmine, Jessamine). Oleacece. 



Sometimes by seeds, but usually by cuttings of the nearly 

 ripened wood, under glass. Cuttings of ripe wood are also 

 employed, and layers are often used. 



Jatropha. Euphorbiacece. 



Cuttings made of firm young shoots will strike in sandy 

 soil in a strong bottom heat. The cuttings, if very fleshy, 

 may be dried a few days before setting them. 



Jeffersonia. Berberidece. 



Seeds should be sown as soon as ripe, or divisions may be 

 made. 



Jerusalem Artichoke (Girasole). See Artichoke. 



Jessamine, Yellow. See Gelsemium. 



Jonquil. See Narcissus. 



Jubaea (Coquito Palm of Chili). Palmce. 

 Propagation is effected by seeds. 



Judas-tree. See Cercis, 



Juglans (Walnut and Butternut). Juglandece. 



All the species are readily propagated by means of strati- 

 fied nuts. Do not allow the nuts to become dry. Artificial 

 cracking should not be done. In stiff soils the seedlings 

 are apt to produce a long tap-root which renders transplant- 

 ing difficult after the first year or two. The tap-root may be 

 cut by a long knife while the tree is growing, or the young 

 seedling may be transplanted. Particular varieties are per- 

 petuated by grafting or budding with any of the common 

 methods. In the north, they are sometimes worked indoors 

 in pots. Common shield-budding works well, if the sap is 

 flowing freely in the stock. Flute-budding is often em- 

 ployed. The improved native sorts are root-grafted in win- 

 ter. Old trees can be top-grafted like apple-trees (see p. 90).
