ORNAMENTAL TREES AND SHRUBS FOR MONTANA 29 



Siberia and Manchuria. It is hardy at this station and is one of the 

 very good plants for the shrubbery or as a specimen upon the lawn. 

 It is propagated from seeds, which should be gathered in the fall 

 and stratified and planted in the nursery row in the spring. 



THE OAKS 



The oaks comprise some of the most ornamental deciduous 

 trees grown in the United States. They are usually propagated by 

 seeds, sown soon after they are ripe in the fall. 



Scarlet Oak: (Quercus coccinea) In .1:904 plants 4 to 6 

 ieet high were secured in Pennsylvania and set out in tlie nursery. 

 In the spring of 1908 they had all winter killed. In the spring of 

 1907 i lants were sent us from the U. S. Depirtn em of Agriculture. 

 In 3 goo all of thf'se plants hac 1 winter killed. It i? not hardy enough 

 fur o-eneisl planting at this altiutde. 



Burr Oak: (Quercus macrocarpcu) This tree i^ native in 

 parts of Montana, where it is known as the scrub oak. It grows 

 into a +ree not exceeding 40 feet in height. It is hardy at this sta- 

 tion but very slow growing and not desirable as a street or shade tree 

 because of its small size and slowness of growth. 



White Oak: (Quercus alba) The white oak is one of the 



very desirable trees for street planting, and at lower altitudes in 

 Montana will no doubt be sufficiently hardy. At this station the 

 white oak has not been hardy. Trees from 4 to 6 feet high were 

 set out in 1904. In the spring of 1908 all had winter killed. 



Pin Oak: (Quercus palustris) The pin oak is often used 

 for street purposes. It is one of the fast growing oaks and does 

 best when planted on moist rich soil. Plants 4 to 6 feet high, set 

 out in 1904, had all winter killed by the spring of 1908. 



(Quercus pedunculata) This is not hardy at this station. 

 Trees planted in 1904 had winter killed by the spring of 1905. 



Red Oak: (Quercus rubra) This is not hardy at this station 

 and trees set in 1903 had all winter killed by the spring of 1905. 



At this altitude the burr oak is the* only tree in the genus that 

 has been found entirely hardy, although at lower altitudes the pin 

 oak and white oak promise to do well and are desirable trees for 

 street and ornamental purposes.
