20 MONTANA EXPERIMENT STATION 



genus are valuable shrubs for group planting and a few make desir- 

 able hedge plants. The white or red flowers in the spring produce 

 beautiful effects and the bright green foliage during summer months 

 and the black or red berries in the fall add much to the landscape. 



Scarlet Thorn: (Crataegus coccinea) In 1904, fifty plants 24 

 to 30 inches in height were secured in Pennsylvania and planted in 

 the experimental nursery. They have proved hardy and in 1907 were 

 transplanted to the college campus. It is a shrub growing to a 

 height of 15 or 20 feet, with bright green foliage during the summer 

 c'nd red berries in the fall, which frequently stay on until late in the 

 winter. It is entirely hardy and will make a vigorous growth on 

 lich moist land. 



Cockspur Thorn: (Crataegus Crus-galli) This is a shrub 

 or tree sometimes growing to a height of 40 feet. The branches 

 have numerous slender spines. The fruit is more or less round, 

 and red. This plant is native from Quebec south to Florida and 

 Texas. It is a very decorative species. In November 1904, the 

 plants w-ere badly injured by a frost as they were late in maturing, 

 and in the spring of 1905 most of them had died. By May 1907 

 they were all dead. 



Black Haw (Crataegus Douglasi) This is native to Montana 

 and is similar in size and characteristics to the Scarlet Thorn except 

 that the fruit is black. 



DEUTZIA 



This genus includes a number of very ornamental shrubs, but 

 unfortunately none of them have so far proved hardy at this station. 



(Deutzia parviflora) This is a shrub growing to a height 

 of 6 feet. In 1898 a single plant was secured from the U. S. 

 Department of Agriculture. It is not hardy and was dead in the 

 spring of 1902. 



(Deutzia scabra) In 1903 ten plants were secured in Penn- 

 sylvania. They were badly injured the first winter, and in the 

 spring of 1904 the tops had died back to near the ground. New 

 growth came from below the surface of the ground, but this was 

 again injured in the fall and winter of 1905. In the spring of 1907 

 they were so badly injured that all were destroyed. 



(Deutzia Lemoinei) In ^903 ten plants of this species were 

 set in the experimental nursery, but by the spring of 1905 all had
