Juglans 



( 456 ) 



Juniperus 



JUGLANS. (WALNUT.) 



Description. Handsome, hardy, tleciduuns trees 

 (ord. Juglandote), useful ornamental subjects for 

 garden or park, and possessing considerable eco- 

 nomic value by reason of their edible Nuts and fine 

 timber. 



Propagation. By seeds (Nuts) sown in autumn 

 or spring; and by grafting or budding for choice 

 varieties. 



Soil. Any deep, fertile soil suils Walnuts. 

 Principal Species and Varieties : 



cinerea, 30', spr., gru. 

 (syjix. cathartica, ob- 

 louga, and Carya cath- 

 artica). Butter Nut.

X regia) . folia, and macropliylla) .

JUNCUS. 



Hardy bog plants (ord. Junceie) of no special 

 value for garden cultivation. 



JUNIPER MOTH. 



The small grey and white moth known to ento- 

 mologists as Ypsolophus marginellus is known to 

 horticulture as the Juniper Moth. The larva; are 

 hatched early in June, and at once spin a web on 

 the erect-growing Irish Juniper, drawing the leaves 

 together and thereby making the shrubs unsightly. 

 Having done this the voracious little pests feed 

 upon the foliage and so cause considerable damage. 

 Hand-picking and vigorous hosing will arrest the 

 enemy, but spraying the trees in May with a weak 

 kerosene emulsion (nee INSECTICIDES) is more 

 effective. 



JUNIPERUS. 



Description. Well-known half-hardy and hardy 

 evergreens (ord. Conifenc), valuable as specimens 

 on lawns, where very tall shrubs would not be 

 suitable, and equally useful in borders and shrub- 

 beries. 



Propagation. By seeds, sown at almost any time 

 they are very slow in vegetating, sometimes taking 

 eighteen to twenty-four months. Or by cuttings 

 in late summer in a shady position in firm soil 

 and preferably, covered with hand-lights. 



Soil. Tire Junipers like a deep, sandy, well- 

 drained loam, but they are not fastidious' in this 

 respect, and will make shapely trees in all but the 

 poorest soil. 



Economic Properties. The fruits of the Com- 

 mon Juniper are used for flavouring <n n while 

 those of the Savin (Sabina) have diuretic proper- 

 ties. A great deal of the light brown, fragrant 

 wood used for cedar pencils is produced by ber- 

 .mudiana and virginiana.
