EVERGREEN TREES 



P. excelsa. The latter tree has made a strong appeal 

 to planters for a long time. It is easily recognized 

 by its large, handsome cones. The native tree, how- 

 ever, while of less rapid growth than the one from 

 Norway, lives longer, is more hardy, and not so subject 

 to injury. The two appear well when planted together. 



The golden Norway spruce, P. aurea, is, as its 

 name indicates, a variety of the better known tree. 

 It is desirable in ornamental planting, because of the 

 clear, golden tints of its foliage. 



The weeping Norway spruce, P. excelsa inverta, 

 appears an eccentric tree when so placed that the full 

 droop of its boughs is displayed. Unfortunately, it is 

 of very slow growth. 



One of the most bold appearing, compact, and hardy 

 of the family is the oriental spruce, P. orientalis, the 

 nature of which is to grow tall and large. It is of 

 particular worth in producing attractive winter effects. 



To produce color in evergreens seems, at present, 

 to be the chief desire of many planters, and no better 

 example of diversity of tone can be found than the 

 Colorado blue spruce, P. pungens. The foliage of 

 this tree is indeed much more blue than green, espe- 

 cially through the month of June. This blue, how- 

 ever, is the kind that suggests green underneath, 

 reminding one of the bloom over a purple grape. 

 The blue spruce, in fact, is not only much used for 

 contrast effects among other evergreens, but is in itself 

 such a beautiful, symmetrical tree that to have it about 

 the home is now a recognized luxury. It is typically 

 an evergreen for formal, highly cultivated effects.
