ORNAMENTAL TREES AND SHRUBS FOR MONTANA 13 



desirable for shrubberies and group plantings. The white flowers 

 are produced early in the spring, and the dark purple berries in the 

 late summer or fall add much to the beauty of shrubberies. 



Common Dwarf June Berry: (Ai -c-lanchie? Botryapiuwi) This 

 is a bush or small tree, rarely attaining a height of over 15 feet. 

 The leaves are more or less oblong and broadly elliptical. This 

 plant is native to New Brunswick, Florida and western Minnesota. 

 Two plants were secured in Iowa in 1904, and set in our nursery. 

 Both have grown and seem perfectly hardy. 



AILANTfiTJS. 



Tree of Heaven: (Ailanthus jjlandulosa*) Only this species 

 of the genus has been tested at this station. It makes a tree 60 

 feet high; the leaves are from i l / 2 to 2 feet long, with 

 from 15 to 25 leaflets. It is a native of China. In 1904 and again 

 in 1905 seeds of Ailanthus glandulosa were planted in a seed 

 bed, but each year the plants killed back to the ground and did not 

 grow the following spring. It is not hardy enough for this climate. 



THE WOODBINES. 



These are climbing vines with alternate leaves, and are closely 

 allied to the grape. They are easily propagated by seeds and by 

 hard or green wood cuttings, and they make a rapid growth. 



Virginia Creeper: (Ampelopsis quinque folia) This is a 

 hardy vine at this station. Fifty plants, two years o?.d, were set 

 c ut in 1904. The first winter the tips killed back ; the second win- 

 ter the plants were covered and they were not injured. In 1907 they 

 were transplanted to the college campus where they are now mak- 

 ing a vigorous growth. 



Engleman Ivy : (JLmpelopsis Engelm^anni) This is appar- 

 ently as hardy as \A. quinquefolia. The essential difference be- 

 tween the two is the smaller sized leaves in the Engleman ivy and 

 a more dense foliage. What is still more important, the Engelman 

 ivy clings to brick or stone walls without support, while the Vir- 

 ginia creeper requires a wire trellis. The common Virginia creeper 

 is a very desirable vine to provide shade over porch screens, espec- 

 ially in locations where some slight protection against the winter 

 sun can be afforded, while the Engelman ivy is excellent to cover 

 the walls of buildings.
