vated strains. It is best transplanted when very young or grafted on established 

 seedlings. 



Juniperus chinensls var. columnaris 



Probably the best of the upright forms of a quite variable species, and with 

 some pruning will develop into a tall, narrow, gray-green column some fifteen 

 to twenty feet in height. In some situations it will replace the native Red 

 Cedar which in smaller sizes is notoriously difficult to transplant. This, like 

 a great many other Junipers, must be carefully protected against attack of the 

 red spider mite. A brilliant green form is sometimes offered. 



JUNIPERUS CHINENSIS var. JAPONICA JAPANESE JUNIPER 



Of a decided vase-shaped appearance when young, this hardy variety spreads 

 out horizontally and seldom reaches a height of more than three or four feet. 

 For the very large rockery or for planting at the bases of buildings. 



JUNIPERUS CHINENSIS var. PFITZERIANA Pfitzer Juniper 



Perhaps the most amenable of all Junipers to the rigors of cultivation — 

 transplants easily, fills up nicely without change of habit if given corrective 

 pruning, and seems to withstand city conditions as well as an evergreen can. 

 While it is sometimes unnaturally trained to a central leader, its normal habit 

 is that of a spreading (wider than high) bush reaching out graceful, horizontal 

 branches which are covered with gray-green foliage. It will, in time, spread 

 to be some ten to twelve feet across if not restrained by pruning out of leading 

 shoots. 



JUNIPERUS CHINENSIS var. SARGENTII Sargent Juniper 



A low, evergreen shrub which sends up ascending branchlets from its pro- 

 cumbent stems. If planted in masses and let go, it will in time cover rough 

 sunny areas with a pleasant mass of gray or bluish green, but does not do well 

 in the shade. 



J uniperus communis var. depressa PROSTRATE JUNIPER 



This is the prostrate form of the pasture Juniper so well known in New 

 England. Since it is such a definite part of our native landscape, its further 

 use in roadside and broad natural development seems indicated. The fruits 

 of this species are eaten by some native birds. Like all forms of J . communis, 

 it must be carefully watched for infestation of the Juniper webworm. Also 

 forms of J. communis may serve as alternate hosts to fungi which cause rust 

 diseases on many rosaceous plants. 



Juniperus communis var. suecica SWEDISH JUNIPER 



A tall, slender plant somewhat like the much-planted Irish Juniper but 

 having branchlets with drooping tips. Preferred to var. hibemica by some 

 tradesmen because of somewhat better early spring appearance. This and 

 other upright varieties of J. communis are hard to group and are losing the 

 garden popularity which they formerly had. 



juniperus conferta (J. litoralis) Shore Juniper 



A creeping, procumbent shrub with upright branchlets covered with spiny, 

 pointed, bluish-green leaves. Suitable for use as a neat-appearing ground 

 cover on open, sandy areas in the warmer sections near the sea. It has inter- 

 esting, large, bloomy, black fruits. 



JUNIPERUS HORIZONTALS var. DOUGLASII WaUKEGAN JUNIPER 



A trailing, fast-spreading variety with steel-blue leaves which become 

 purplish in winter. It will do well in dry, sandy situations and makes an
