shrubs. Thus, we find the Norway spruce, a native of Europe, 

 widely planted in the northeast as a shade tree, and used in rows 

 as a windbreak. The dwarf Mugho pine is much used as a low 

 shrub, as are many horticultural varieties of the arbor vitaes, 

 junipers, coast white cedars and yews. Perhaps one of the most 

 desired ornamental evergreens is the blue spruce, which with its 

 variety the Koster blue spruce, is used throughout the northern 

 half of our country because of its fine shape and beautiful foliage 

 when planted alone or widely spaced. Of course many of our 

 native forest trees are transplanted from the forest to yards and 

 gardens, and many more are nursery grown from seed collected 

 in the forest. Many of the Angiosperm trees are beautiful 

 when in flower, or when the foliage turns to brilliant colors in the 

 fall, but the evergreen Gymnosperms are stately and beautiful 

 throughout the four seasons of the year.
