RHODODENDRON M UCRON ATUM. 



The well-known A/.alew ledifolia" 

 or "Azalea indica allKi" but correctly 

 Rhododendron niucronatuin is an old 

 and favorite plant in American gar- 

 dens. Just when it was introduced is 

 uncertain hut it was in cultivation 

 with Mr W. P. Cusliins. Holmont 

 Place, Watertown, Mass.. in February, 

 18SS. Round Hoston this plant is not 

 properly hardy though in a few gar- 

 dens it lives and flowers out-of-doors. 

 On the banks of the Hudson and on 

 Long Island. New York, it is perfectly 

 hardy and each spring is laden with 

 its large, pure-white, fragrant blos- 

 soms. The largest and oldest plant 

 that the Arnold Arboretum has record 

 of is that shown in the accomi>anying 

 picture. It Is growing on the estate 

 of Henry F. Dupont. Winterthur. Dela- 

 ware, and has been in the possession of 

 the family since sometime between 

 1835 and 1840. This plant the owner 

 courteously informs us is 6 ft. 9 inches 

 high and 12 ft. 2 inches through. In 

 Japan where this Azalea is grown In 

 nearly every garden I did not see a 

 specimen comparable in size with Mr. 

 Henry F. Dupont's magnificent plant.

ARBORETUM NOTES. 



Tripterygium Regelii 



Climbing plants with handsome 

 foliage and a conspicuous inflores- 

 cence easy to grow and hardy in New 

 England are not too numerous, and 

 Mr. Jack's introduction several years 

 ago from Korea of Tripterygium 

 Regelii made an important addition 

 to the number. It Is a near relative 

 of the Bitter Sweets (Celastrus) and 

 a native of Korea and northern Japan, 

 where it rambles over rocks and 

 bushes, and often climbs with stems

fifty or sixty feet long into the tops 

 of trees. The leaves are long-pointed, 

 dark green, and often six inches in 

 length. The small white flowers are 

 produced In narrow open clusters ten 

 or twelve inches long, and they are 

 followed by showy, three-lobed. and 

 three-winged fruits from half an inch 

 to an inch long. By pinching the 

 young shoots this vine can be grown 

 as a shrub. Such a plant is now 

 growing and flowering in the Shrub 

 Collection, where it is also growing 

 naturally on the trellis next to the 

 different species of Celastrus. 



Periploca sepium 



This is another handsonie twining 

 plant which the Arboretum owes to 

 the labors of Mr. Jack in Korea. It is 

 growing on the trellis near the Trip- 

 terygium and is unusually full of 

 flowers this year. It Is a plant with 

 slender stems, pointed dark green and 

 very lustrous leaves about three and 

 a half Inches In length and not much 

 more than half an inch in width, and 

 small flowers in few-flowered clusters. 

 The flowers do not make much show- 

 when seen from a distance, but on 

 close examination show that they are 

 green on the outside, dark purple with 

 a five-lobed crown at the base on the 

 Inside, and that they are pleasantly 



fragrant. The plants In the Arbore- 

 tum have not yet produced then- 

 slender pod-like fruits, but as they 

 send up numerous root suckers this 

 vine can be easily propagated and 

 might soon become common in north- 

 ern gardens. Much better known is 

 Periploca graeca from southern 

 Europe and western Asia which has 

 not yet proved hardy in the Arbore- 

 tum 



Lonicera prostrata 

 The attention of persons looking 

 for plants suitable for ground cover 

 is directed to this Honeysuckle dis- 

 covered by Wilson near Sungpan in 

 Szech'uan, western China, at an al- 

 titude of about twelve thousand feet 

 above sea-level. It has long slender 

 branches which He flat on the ground, 

 so that the plant is only a few inches 

 high, small bluish green leaves, small 

 inconspicuous yellow flowers and 

 small red fruit. As a garden plant 

 this Honeysuckle has nothing to com- 

 mend it but its habit which should 

 make It useful to cover the ground 

 among large shrubs and on the bord- 

 ers of shrubberies. Lonicera pros- 

 trata Is growing on the southern slope 

 of Bussey Hill with the other new 

 Chinese shrubs. 



\ Keniarkable .\zalea 



The Pennypack Greenhouses, at 

 Holmesburg, near Philadelphia, have 

 been purchased by Dave AUman. for- 

 merly of Pornell University. Posses- 

 sion was taken the first of June. 



Jos. L. Barnltt. Jr., salesman for 

 A. T. Bunyard, of New York, was re- 

 cently married to Miss Maud B. Mar- 

 tin, of Ayr, Scotland. Mr. Barnltt Is 

 a veteran of the late war, and met Miss 

 Martin when in Scotland. He will b* 

 connected with the Newport store of 

 Mr. Bunyard this summer. 



More and more the chain idea of 

 flower stores is growing. A number 

 of florists now have several stores in 

 the same or different cities. H. L. 

 Thompson, of Brighton, Pa., is one of 

 the chain store enthusiasts. He now 

 has stores in Rochester, New Brigh- 

 ton and Beaver Falls.
