2 MONTANA EXPERIMENT STATION 



stems closely covered with spines. The leaves are very dark green 

 and shining above, which gives the plant a .striking appearance. 

 The flowers range in color from white to red, and are two to three 

 and one-half inches across. In 1904 fifty plants were put in the 

 experimental nursery. In the fall of that year they did not mature 

 thoroughly before freezing weather and were slightly injured dur- 

 ing the winter. Since that time they have not been seriously in- 

 jured and are now making vigorous growth on the college campus, 

 where they were planted in the spring of 1907. Rosa rugosa, with 

 its varieties, is among the best of the rose plants for this latitude. 

 They are valuable for shrubbery or for specimens on the lawn. 



Prairie Rose: (Rosa setijjera) At this altitude this species 

 is not hardy. The plants set out in 1904 all winter killed before 

 the spring of 1907. 



Harrison's Yellow Rose : (Rosa hemisphearica var. Harisoni) 

 This is a rather tall form, reaching a height of 6 feet or more. It 

 is very hardy and blooms freely, the flowers being double and of a 

 bright yellow color. The leaves are bluish green and the stems 

 dark red, making it an attractive plant even after the flowers are 

 gone. This rose has not been tested at the station but it is to be 

 found on many lawns in Bozeman and other cities and towns of 

 about the same altitude, where it is perfectly hardy, regularly sur- 

 viving the winters without any protection. It is to be recommend- 

 ed for general planting. 



RASPBERRY AND BLACKBERRY. 



( Rubus xanthocarpus) This plant is a native of China and 

 was introduced into the United States by the U. S. Department of 

 Agriculture. It is not hardy at this station and has been discarded. 



Rocky Mountain Flowering Raspberry: (Rubus deliciosus) 

 This plant is a native of the Rocky Mountain region and is hardy 

 at this station. It is not, however, particularly valuable as an orna- 

 mental plant. 



Cultivated Red Raspberry : (Rubus strigosus) , Common 

 Black Raspberry (Rubus occidentalis) , Northern Dewberry 

 (Rubus villiosus) , and Common Blackberry (Rubus argutus) are 

 not hardy at this station unless given some covering during the 

 winter months. At lower altitudes in the state these plants are 

 hardy and can be grown without winter protection.
