No evergreen is better for mass plant¬ 
ing than the Hemlock, with its graceful 
habit and featiiery foliage. 
Hemlock 
('Tsuga Canadensis ) 
Of American evergreens, none hold higher place for mass 
planting than the Hemlock, particularly the variety Tsuga 
Canadensis. It is valuable for either lawn or woods planting; 
grows well in groups on hills or in the valleys, thriving in any 
land that is of a loam or sandy loam nature and well drained. 
It is not partial as to its surroundings, growing equally well in 
sunlight or shade, and is unsurpassed for hedge work. Through¬ 
out Pennsylvania this is one of our most beautiful trees. 
The Hemlock makes a large tree. It is of rapid growth; its 
general habit straight and graceful, 
the branches somewhat pendulous, 
delicate in appearance and clustered 
with rich dark green foliage. 
Colorado Blue

able trees when used as a specimen 
in ornamental plantings, as it gives

uation. Hardy in any exposure, a 
good grower, branches stiff'and close, 
foliage of an exceedingly rich silvery 
blue.
