ORNAMENTAL TREES AND SHRUBS FOR MONTANA 17 



will produce a shrub or small tree sometimes 20 feet in height. Be- 

 cause of its hardiness, it is valuable for shrubberies or group planting. 

 The flowers are pea-like in form, yellow in color and are produced in 

 late spring or early summer. The bark of the young plant is 

 bright green. It is readily propagated from seeds sown in the spring. 

 It is native in Russia and Manchuria. 



(Caragana frutescens) In 1898 plants were secured from the 

 U. S. Department of Agriculture and set out in the experimental 

 nursery. They have been entirely hardy and are now growing on 

 th college campus. This is a shrub which grows 6 to 10 feet high ; 

 the flowers are yellow in color, produced singly, from ^ to I inch 

 tong. They are borne in May or June. It is a native of southern 

 Russia and China. 



CATALPA. 



This genus includes several deciduous trees, with opposite long 

 petioled, large and simple leaves. They are highly ornamental, with 

 a large bright green leaf and showy flowers. The soft coarse- 

 grained wood is very durable, when set in the soil, which makes it 

 valuable for fence posts. Some of the species make a rapid growth 

 and are much planted in certain sections of the United States for 

 economic uses. 



Western Catalpa: (Catalpa speciosa) In 1903 five hun- 

 dred plants were set in the experimental nursery at this station. 

 For three years they died to the ground each winter and in the spring 

 of 1906 they were plowed out and destroyed. The growing sea- 

 son is too short at this altitude for the wood to mature, the plants 

 usually being killed back by the first hard freeze in the fall. 



CELASTRUS 



This genus includes several shrubs, most of which are climbers. 

 Only one species has been tested at this station. 



False Bitter Sweet: (Celastrus scandens) This is a climb- 

 ing vine, often reaching 20 feet in height. It is native 

 from Canada through the western Mississippi valley to New Mexi- 

 co. In 1904 plants 12 to 18 inches high, were secured in Pennsyl- 

 vania and planted in the experimental nursery. They killed to 

 the ground each winter and were destroyed in the spring of 1908, 

 not proving hardy at this altitude.
