EVERGREENS: THEIR USES AND CULTURE

five feet tall, which retains the lower limbs for many years. As it makes its 

 growth slowly it is well suited while young for use upon small lawns. The 

 oriental spruce is one of the very best evergreens for any situation where a fine 

 specimen is wantedi and, with the exception of its slower habit of growth, is in 

 every way superior to the popular Norway for ornamental purposes. 



White Spruce. Picea Canadensis B. S. P. Of the spruces native to America 

 one of the most pleasing, on account of its conical shape and compact habit of 

 growth, is the white spruce. Variously estimated at from fifty to one hundred 

 and fifty feet in height, the white spruce bears foliage of a bluish-green color, 

 which is unpleasantly aromatic when crushed. It has been much used as an 

 ornamental, and when grown in a group with Norway spruce or other dark- 

 colored trees the contrast formed is a lively and agreeable one, although the 

 white spruce is longer lived and of slower growth than the Norway. It is a 

 native of the north, as its natural range extends from northern New England 

 through Canada to the Arctic Circle and westward through northern United States 

 to Montana, and it is therefore well suited to cold regions. The white spruce 

 does not stand heat well and in central United States the foliage is liable to be 

 attacked in summer by the red spider, which soon causes it to look discolored 

 and thin. For the construction of windbreaks in the extreme northern states no 

 tree is superior to the white spruce.

Colorado Blue Spruce. Picea parry ana glauca. Tco many good things can 

 scarcely be said of this rarely beautiful conifer from the mountains of Colorado. 

 While trees grown from seed vary greatly in shades of color, the finest have 

 foliage of rich steel blue which is handsomest in summer and fall, becoming 

 somewhat dimmer in winter. Nothing more attractive in the evergreen line can 

 be easily imagined than the young growth on a well-colored Colorado blue
