THE ARNOLD ARBORETUM 43 



compact clusters of white flowers, followed by shining black fruits. 

 No other Viburnum flowers more profusely. In the collection of 

 Viburnums are many representatives of western Asia. Unfortu- 

 nateh', however, the group does not include the beautiful evergreen 

 species of southern Japan and China, which are not hardy in New 

 England. 



The most interesting specimens in the collection are those which 

 belong to the Opulus group, Viburnum Sargcntii being one of the 

 best representatives. It is hardy, shapely, and the flowers are pure 

 white. When this Viburnum is blooming it is the most beautiful 

 of all its class. Seek it out next June at the side of Bussey Road. 



The Azaleas occupy a place of their own on the side of both the 

 Bussey and Hemlock Hills. The most popular collection is on the 

 former elevation, where a large number of the plants are grouped 

 along Azalea path. Few flowers in the Arboretum attract more 

 attention or give greater pleasure. Most gorgeous of all the 

 Azaleas is Kacmpferi, which was introduced by the Arboretum 

 into the gardens of the United States and Europe in 1893. It was 

 first raised from seed collected by Professor Sargent in Japan. It 

 is perfectly hardy, but the flowers are so delicate, when exposed to 

 the sun, that they soon fade. The greatest beauty of Azalea 

 Kaempferi is obtained when the plants are grown in deep or partial 

 shade. 



In introducing Azalea Kaempferi to New England the Arnold 

 Arboretum has given our gardens a prize not readily excelled. It 

 is a magnificent plant, and in time will be grown in great numbers, 

 as landscape gardeners come to know it better. Moreover, it is 

 just as adaptable to small gardens as to large estates. No one 

 living in Boston should fail to see the Azalea show at the Arboretum. 



Another Azalea which makes a wonderful burst of bloom is 

 pouhhanense which was introduced into the Arboretum by Mr. 

 Jack on the occasion of his trip to Korea some years ago. It was 

 named for Poukhan, a Korean mountain, where it has been found 

 by a French missionary. A beautiful round-topped, compact 

 shrub, with large rosy-pink and fragrant flowers, it seems to be 

 perfectly hardy an;v'^vhere in the Ai'boretum, where it has been 

 flowering for several years. It should prove a good plant for New 

 England gardens, and people who are interested in Rhododendrons
