TREES 
Pines: The pines are unquestionably the noblest of our conif- 
erous trees. From the standpoint of the landscape architect they 
are best adapted to large mass plantings where something like forest 
conditions can be established. The American white pine is the best 
species for landscape use, though there are other kinds which are 
worth while under special conditions. 
Retinespora: These are Japanese species extensively grown 
in the nurseries for ornamental effects. They are valuable for fancy 
groups and small masses. 
Spruce: The Norway spruce is a favorite for landscape plant- 
ing and though it is short lived may be widely used. The Colorado 
blue spruce has had an extraordinary vogue and has been greatly 
overplanted. The spruces make good hedge plants and wind-breaks. 
Outside of this use they are more valuable for large forest-like plant- 
ings than for individual specimens on lawns.
