Trees 161 



White and pink. June; 6 inches to 2 feet. Very variable. In 

 terminant umbels. Peaty or sandy soil, with rhododendrons and 

 azaleas. See also FETTER BUSH. 



SAVIN (Juniperus Sabina). A prostrate shrub, with long, stiff, straggling 

 dark green branches, but free method of growth. 3 to 5 feet. 



SPRUCE, BLUE (Picea pungens, var. glauca). The best-coloured coni- 

 ferous evergreen. Beautiful steel-blue. Most imposing in early 

 summer. Slow grower, attaining 75 feet. Hardy, but compara- 

 tively short-lived, the base becoming ragged at 35 years. Many 

 forms of this in the trade. The highest coloured of all is known as 



Koster's. Also drooping and weeping forms. , DOUGLAS 



(Pseudotsuga Douglasii.) Rapid grower, almost too fast for 

 garden growth. 200 feet. Colorado trees are hardier than those 

 from California. Transplants readily. Rich dark green foliage 



with faint blue sheen beneath. , ENGELMANN'S (Picea Engel- 



manni). Somewhat resembling the blue spruce in tone of colour 

 but less brilliant. Needles not so long but softer and flexible. 



Perfectly hardy. 80 to 100 feet. , NORWAY (P. ex eels a). 



The fastest growing conifer. 100 feet. Also one of the hardiest 

 and withstanding strong winds. Sombre, dark green. Does best 

 in moderately rich soil with good feeding. Otherwise loses its 

 beauty early, before the white pine. Graceful branches, drooping. 

 Needs ample space for full development of individual character. 



Branches to the ground, making a perfect cone. , ORIENTAL 



(P. orientalis). Most refined of all spruces. Ascending branches 

 with pendulous branchlets. Rich, dark foliage. Makes a beautiful 

 lawn specimen when old enough to bear cones. The staminate 

 flowers a brilliant carmine, standing erect like candles on a Christ- 

 mas tree. Slow growing and, though discoloured by spring frosts, 



is hardy. , WHITE (P. alba). The hardiest native spruce, 



and ranking next to the white pine in rapidity of growth. Usually 

 70 feet, but occasionally 150 feet. Light glaucous green foliage. 

 Dense tree, regular conical shape. Excellent windbreak. Will 

 grow right down to the water's edge. 



SPURGE, MOUNTAIN (Pachysandra terminalis). Excellent cover plant 

 thriving in the sun or shade in any ordinary soil, making a carpet 

 about 6 inches thick. Flowers white, followed by white berries in 

 winter. Leaves lightish green and thick.
