30 MONTANA EXPERIMENT STATION 



RHAMNUS. 



Buckthorn:. (Rhamnus cathartica) This is a shrub growing 1 

 to a height of 10 or 12 feet, usually with thorns. It is a native of 

 iiurope, Western Asia and Siberia. It is very desirable for orna- 

 mental hedges. 



In 1904, plants 6 to 12 inches high were secured in Pennsyl- 

 vania and planted in the experimental nursery. Since that time 

 they have not ben injured by freezing in any way. In 1907 they 

 were placed on the college campus and have proved entirely hardy. 

 Ihe buckthorn is much used in eastern United States and Europe 

 for hedges and is valuable for that purpose and for large shrubberies 

 in Montana. 



RHUS. 



This genus includes several species of trees and shrubs, with 

 alternate pinnate leaves. Most of the species are beautiful orna- 

 mental plants, and if they are adapted to the soil and climatic con- 

 ditions in which they are to grow they deserve a place in any orna- 

 mental landscape. They are propagated from seeds, layers, root 

 cuttings and by hard wood cuttings. 



Smoke Bush: (Rhus Cotinus) When tested at this station 

 it has been found not to be hardy enough to withstand our climatic 

 conditions. 



Chittamwood : (Rhus Cotinoides) This grows into a small 

 tree, but is not hardy at this station. 



Staghorn Sumach: (Rhus typhana, VOLT, laciniata) This 

 plant was set out in the experimental nursery in 1904. The tips 

 killed each year but new shoots came out from below the injured 

 portion and made a growth of from 4 to 6 feet each season. The 

 deeply cut foliage produces beautiful effects in the shrubbery, and 

 while it is not entirely hardy at this altiutde, it will still produce 

 good effects in any landscape. 



CURRANT AND GOOSEBERRY 



Besides the common currants and goseberries, there are other 

 species grown for ornamental purposes. There are several native 

 forms of the wild currant and gooseberry growing in Montana 

 which, when placed under cultivation, make desirable ornamental
