ORNAMENTAL TREES AND SHRUBS FOR MONTANA 11 



rent year's growth kills back each year. It is not a hardy plant at 

 this station. 



Norway Maple: (Acer platanoides) This is a large tree, 

 often attaining a height of 100 feet. The leaves are five-lob ~d and 

 from 4 to 7 inches across. It is native to Europe and the Caucasus 

 region. It is a large, beautiful tree, with round, symmetrical head, 

 producing dense shade. It does not grow as rapidly as the soft 

 maple and has a tendency to* form branches near the ground which 

 sometimes makes it undesirable as a street tree. 



In 1904, five hundred plants, 15 to 24 inches high, were secured 

 in Pennsylvania and planted in our nursery. They were injured 

 somewhat the first winter, but since that time have made a good 

 growth. In 1907, one hundred plants, 18 to 24 inches high, were 

 obtained in North Dakota and planted in our nursery. They were 

 injured badly by freezing the first winter. In 1908, one hundred 

 small plants were secured in Pennsylvania and planted in our nurs- 

 ery. These were killed to the ground in the winter of 1908-9, al- 

 though new growth is coming out at this time below the injured 

 portion. 



The second year after transplanting very little injury usually 

 results. The Norway maple promises to be one of the best trees 

 for general ornamental planting in Montana. While it grows slow- 

 ly, it is fairly hardy, forms a beautiful symmetrical head, produces 

 good shade, is free from pests and will stand the adverse conditions 

 found in cities fairly well. At lower altitudes than Bozeman, even 

 the young plants of this tree will be entirely hardy. 



Sugar or Rock Maple: (Acer saccharum) This is a large tree 

 growing to a height of 120 feet, with leaves three- to five-lobed and 

 3 to 6 inches long. The leaves take on a bright scarlet color 

 in the autumn, which produces a very beautiful effect. This is one 

 of the best of the maples for shade and ornamental purposes and is 

 a desirable street tree. It is native to eastern North America. Un- 

 fortunately the young trees we have planted have not proved en- 

 tirely hardy at this station, although at lower altitudes in the state 

 it is growing well and seems to be quite hardy. 



In the spring of 1903, two hundred and fity plants, from 12 to 

 18 inches high, were secured in Iowa. They did not mature in the 

 fall before freezing weather and were injured by the first freeze
