transplanted stock from 8 to 12 inches in height. This variety 

 is especially adapted to northwestern Iowa. 



It is questionable if the western yellow pine should be used 

 to any great extent for commercial planting, in the state, since 

 in most localities faster growing trees are available. 



The tree is used extensively for ornamental planting. 

 Open grown specimens are symmetrical and the coarse, long 

 needles often give a pleasing contrast to the foliage of the 

 broadleaf trees or other evergr.eens. 



AUSTRIAN PINE (Pinus austriaca) 



The f lree\ The Austrian pine is a native of Europe but 

 has been widely planted in the United States with splendid 

 results. Iowa grown treesform a straight, stocky trunk with 

 heavy limbs, when open grown. The branches do not appear 

 in such distinct whorls as is the case with the white pine, con- 

 sequently the ornamental value is somewhat le^s aitho the tree

 almost equal to 

 that of the Scotch 

 pine. In hardiness 

 the tree compares 

 favorably with the 

 yellow and Scotch

 years or more, 

 is generally classed as a short-lived species.
