PRUNING JASMINE. 



190 Encyclopaedia of Gardening 



will thrive in a greenhouse, and bears white flowers in late summer 

 (see Botanical Register, t. 91). Officinale is the common white hardy 

 Jasmine (Bot. Mag., t. 31). The hardy Jasmines will thrive in 

 any fertile soil; equal parts of peat and loam, with 

 some sand, suit the others. The outdoor kinds 

 may be increased by layers or suckers, the indoor 

 by cuttings taken off with a heel of old wood and 

 inserted in sandy peat under a bell-glass. When 

 the young plants begin to grow the tip should be 

 pinched out, when side shoots will break freely. 

 The branches should be thinned when they get 

 crowded, and young wood cut to spars.

Juglans, Walnut (ju-glans, from Jupiter Jovis, the 

 god ' and glans> a ^t literally, Jupiter's nut. 

 Ord. Juglandeae). The Walnut, Juglans regia, is a 

 hardy deciduous tree, thriving in any fertile soil. The nut is 

 encased in a thick green case, which will decay after storing in 

 autumn. Propagation is by seeds for the common kind, by budding 

 or grafting for the special varieties. There are several varieties. 



Julus (Millipede). The species complanatus and pulchellus 

 guttatus are short, many-legged, quick-moving " insects," often 

 found about the roots of plants. Soot water and brine may be used 

 to get rid of them ; or they may be trapped with pieces of Mangold. 



Juniperus, Juniper (junip-erus, from juniperus (Celtic), rough. 

 Ord. Coniferae). Handsome evergreens, some hardy, others re- 

 quiring the shelter of a greenhouse. Good varieties are well worth 

 growing as lawn plants. They do not care for stiff, damp soil, 

 thriving best in light, friable ground. Propagation is by seeds or 

 cuttings in August in a frame or under a bell-glass. Chinensis aurea 

 and C. albo-variegata are good lawn trees. There are several good 

 varieties of communis, the common Juniper, notably fastigiata and 

 glauca. Virginiana is the Red Cedar, and there are many varieties 

 of it, such as argentea, aureo-variegata, and pendula. Bermudiana, 

 the Bermuda Cedar, must be grown in a greenhouse. 



Justicia (justl-cia, after Mr. J. Justice. Ord. Acanthaceae) . 

 This genus is closely related to Jacobinia, and in fact is incorporated 

 with it by modern botanists, but certain species are grown in 

 gardens under the name of Justicia. Carnea, coccinea, ghiesbregh- 

 tiana, and magnifica are cases in point. For culture, see Jacobinia.
