the provinces is var. depressa, also sometimes called var. nana. 

 It forms broad masses usually on stony or dry soil, and reaches 

 a height of three to four feet. It is seldom planted for orna- 

 ment, but it does much to improve the appearance of otherwise 

 barren places. Var. aurea is a golden-leaved form of var. 

 depressa, and is also hardy and rather attractive. The var. 

 montana, sometimes called alpina, is found in the northern 

 and mountainous parts of Canada. The most ornamental 

 forms of the common juniper are var. suecica and var. hihernica. 

 Neither of these is, however, quite satisfactory at Ottawa, as 

 the tips of the previous year's growth are usually killed in 

 winter and the branches are rather unsightly until new growth 

 has been made. Both are very compact and upright growlers, in 

 fact, quite columnar. The Irish juniper has greener leaves than 

 the Swedish. They do well in the coast region of British Colum- 

 bia. The Swedish is, perhaps, a little hardier than the Irish. 



Prostrate juniper, Juniperus horizontalis, has been con- 

 founded with J. Sahina. It growls wild in most of the provinces 

 of Canada and usually lies close to the ground and trails over 

 it, where it forms a virtual carpet. The foliage is bluish and 

 when large masses are seen it has a very pleasing effect. It 

 does well as a ground-cover in the prairie provinces. 



The red-cedar, Juniperus virginiana, does well in eastern 

 Canada as it is native there, but, owing to the dullness of the 

 foliage, the type is not particularly valuable for ornamental 

 planting. One of the best varieties is elegantissima, which is 

 yellow-tipped, making a pleasing contrast in color. The habit 

 is also more graceful than some. The var. Schottii has brighter 

 green foliage than the type and is more attractive. Var. glauca 

 has bluish foliage, which is quite distinct, but does not seem 

 so hardy as the others. The pyramidal form is quite striking 

 in outline, but the foliage is not very attractive.
