Picea—The Spruces 
Culture: Moist, rich soil. Easily grown. 
T HE Spruces are a hardy and toler¬ 
ant race and range from the well- 
known Norway Spruce to such 
types as Roster’s Blue and, on the other 
side of the scale, the dwarf Spruces. 
THE NORWAY SPRUCE 
(Picea excelsa) (P. Abies). Zone II. 
50 to 70 feet. At maturity a tall dark green 
pyramid with pendulous almost weeping branch¬ 
es. The root system is shallow and for that reason 
Norway Spruce can be planted in thin soils, over 
hard-pan or bed rock. Its great popularity attests 
its fundamental virtues.

(Larger sizes priced on request) 
THE WHITE SPRUCE 
(Picea alba). Zone I. 
This variety makes a shapely pyramidal tree 
and is one of the quickest growing spruces, being 
exceeded only slightly by the Norway Spruce. In 
New England generally it proves more satisfac¬ 
tory than this latter variety and forms a much 
denser and more perfect specimen.

THE BLUE SPRUCES 
The Colorado Spruce (Picea Pungens) 
produces both green and blue trees from its 
seed. The best of the blue trees are selected and 
sold as Colorado Blue Spruce. We offer the 
following carefully selected specimens. All are 
of a definite blue color, although not as uniform 
in tone as Roster’s Blue Spruce. Zone II.
