ORNAMENTAL TREES AND SHRUBS FOR MONTANA 41 



zontal and grow out from the main stem in apparent whorls. The 

 tree takes a pyramidal form. The color of the leaves on different 

 trees varies from dark bluish green to a silvery white. It is a native 

 of the Rocky Mountain district of Wyoming and Colorado. It 

 makes a very beautiful tree as a specimen on the lawn and is abso- 

 lutely hardy at this station. This is probably the best of the ever- 

 greens for ornamental planting in Montana. 



THE PINES. 



There are many pines and several of them are native in Mon- 

 tana. Few, however, have much value here as ornamenal trees. 

 The following kinds are hardy at this station: Pinus Austriaca, 

 Pinus monticola, Pinus Mughus, Pinus Murrayana, Pinus 

 palustris, Pinus sylvestris, Pinus Koraiensis and Pinus ponderosa, 

 var. scopuloruTYi. 



(Pinus Koraiensis) This plant grows into a tree about 100 

 feet high. The leaves are dark green and glossy above and bluish 

 white on the inner sides. They are from two and a half to four inches 

 long. It is a native of Japan and Korea. It is of rather slow 

 growth but forms a dense, broad pyramidal head. Seeds of this 

 plant were sent us from U. S. Department of Agriculture and sown 

 in the spring of 1907, since which time the young plants have been 

 entirely hardy. 



Yellow or Bull Pine: (Pinus ponderosa) This plant is a 

 native of Western Montana. Seeds wene sown in the station nurs- 

 ery in the spring of 1907. The young plants died in the winter of 

 1908-9. Tests will be continued with this variety and it is probable 

 that the larger trees will prove hardy. Several trees of this variety 

 on the college campus are doing well and have not killed back. 



Mugho Pine: (Pinus Montana, var. Mughus) Seeds of 

 this plant were placed in the seed bed in the spring of 1907. The 

 young plants have been entirely hardy since that time and promise 

 to be hardy at this station. 



P^EUDOTSUGA 



Douglas Spruce: (Pseudotsuga Douglasii) This tree is a 

 native of Montana and is perfectly hardy at this station. It is val- 

 uable for shelter belts and wind breaks, and is also good for group
