26 MONTANA EXPERIMENT STATION 



Large Flowering Mock Orange: (Philadelphus inodorus) 

 In 1904 plants i to 2 feet high were secured in Pennsylvania 

 and set out in the experimental nursery. Since that time they have 

 proved to be almost hardy and are a valuable addition to ornamental 

 plants at this station. Given slight winter protection it is hardy. 

 The terminal growths frequently kill back in the winters but not 

 enough to seriously interfere with the development of the plant. 



^Philadelphus Lemoinei) This plant is a hybrid between 

 P. microphyllus and P. coronarius. In 1904 plants one foot in 

 iieight were secured in Pennsylvania and set out in the experimental 

 nursery. Since that time they have proved to be almost hardy 

 when given slight winter protection. In exposed places terminal 

 growths kill back but rarely enough to seriously interfere with sub- 

 sequent growth. This is a very desirable plant for the shrubbery 

 group. 



PHILODENDRON. 



(Philodendron Amurensis) Seeds of this plant were sent 

 from the U. S. Department of Agriculture and planted in the spring- 

 of 1907. The young tips were winter killed in the spring of 1908-9. 

 It does not promise to be entirely hardy at this station. 



THE POPLARS. 



These are all soft wooded trees. Poplars, as a class, are very 

 last growing, usually producing trees not above medium size. They 

 are easily propagated, growing readily from hard wood cuttings. 

 They thrive in a great variety of soils and do best when grown on 

 land that is rather moist. They are valuable for shelter belts and 

 wind breaks, and are used in certain sections for street and shade 

 trees. Poplars are dioecious, that is, the staminate and pistillate 

 flowers are borne on separate plants. The pistillate plants are the 

 ones that produce the so-called cotton, which is so undesirable in 

 the spring when the seeds are ripe. When propagated by cuttings 

 from the staminate trees only, the cotton does not appear. Several 

 kinds have been tried at this station. 



Narrow-Leaved Cottonwood: (Populus an gusti folia) This 

 tree is native to many parts of Montana and grows to a height of
