THE NATIONAL NUKSERYMAN 
203 
presented for the coining .year, seemed so well worth 
while to those present at Chicago that tlie American As¬ 
sociation voted, almost imanimonsly to take over and 
conduct the work of the Organization for Market De¬ 
velopment, w hieh was formed at Cliieago last year. 
Market Development is no panacea that w ill cure all 
nursery ills. But it is sometliiiig definite and tangihle 
that will help all nurserymen, to the extent the Associa¬ 
tion hacks it up. And it may he made to help individual 
nurserymen, to the extent that they are w ide aw ake and 
alert to the advantage of the things the Nurseryman’s 
National Service Bureau can do for them individually. 
For instance, here are some specific things that can be 
made to help you, in your own individual business. 
Articles for Local Newspapers 
During the past.spring we sup[)lied several huudred 
newspapers with business building articles on trees, 
shrubs, fruits and perennials. A similar series is being- 
prepared for this fall and next spring. These articles 
are available for every member of the American Asso¬ 
ciation. They will he supplied without cost, to local 
papers (one in a city) in the ten-itoiy in wdiieh you sell. 
Send in Your List 
Illustrated Lectures. The first of three lectures, 
with colored slides, “Beautify the Home Grounds,” will 
be supplied without cost to garden eluhs, improvement 
societies, etc. You can provide for the use of these in 
the territories in which you sell. Write for dates and 
particulars. 
NOTES FBOM ARNOLD ABBOB^^^’UM 
Rhododendron (Azalea) calendulaceuai. A lo\ur of 
flowers who has had the good fortune to see the yellow- 
flow ei^ed Azalea in June on the wooded slopes of the 
southern Appalachian Mountains can never forget it. 
North i^nerica does not offer a more beautiful flower 
show. No other North American shrub has such bril¬ 
liantly colored flowers; and no other iVzalea hardy in 
New England can be compared wdth it in the variety of 
color found in its flowers. The flowers of the Korean 
Azalea Schlippenbachii are larger and more delicate in 
texture and color, and those of the Japanese A. Kaempferi 
are more surprising, for it is always a surprise to find the 
bright red flowers of this Azalea on a bare New England 
hillside. These plants when they are in flower look ex¬ 
otic here and do not fit our American surroundings as 
well as our yellow-flowered plant. The flowers, too, of 
the American plant remain in good condition longer than 
those of any of the Asiatic Azaleas, and they were not 
injured by the excessive heat wdiieh spoiled the 
flowers of many other plants . A good many plants of 
R. calendulaceam have been raised at the Arboretum from 
seed, and many of the seedlings w hieh are now^ blooming 
on Azalea Path show^ the variation in the color of the 
flow^ers from clear yellow^ to flame, which adds to the 
interest of a collection of these plants in early June. 
Single plants of this Azalea have also been planted among 
other shrubs on the borders of some of the drives, and 
these show how this Azalea can he used with advantage 
in New England plantations. 
Some Interesting Boses. The Boursault Bose {Rosa 
LlieriUeranea) has not before carried more flowers than 
it has borne this year. This Bose, wdiieh was raised in 
France early in the last century, is believed to he a hybrid 
of R. clirnensis and the European R. pendulina, and owes 
its popular name to Monsieur Boursault who a hundred 
years ago had a garden in the Rue Blanche, now Chausce 
d’Antin, famous for its collection of Boses. There have 
been several forms of the Boursault Bose, the one in the 
Arboretum collection, which has pale rose red, partly 
double flow ers,'is not an uncommon plant in old New Eng¬ 
land gardens. It is a tall, vigorous and perfectly hardy 
shrub wdth gracefully spreading stems. Rosa Marreiii 
has not before flowered so freely in the Arboretum; it is 
a tall broad shrub with arching stems, pale green leaves, 
and large pink flowers. It is a native of northern Hok- 
kiado and of Saghalien where it was discovered by the 
late Ahhe Faurie who sent seeds to the Arboretum in 
1908. This plant, which is probably still rare in cultiva- 
ition, promises to be a good addition to the single-flowered 
Boses which can be successfully grown in this climate. 
The single-flowered Chinese form of R. Roxburgii (var. 
normalis) is flowering for the first time in the Arboretum 
and proves to have larger flowers than any other Bose in 
ithe collection, with the exception of R. rugosa and its 
varieties. The petals are pale shell pink and conspic¬ 
uously notched at apex. The fruit of this Bose wall 
probably be almost as ornamental as the flowers, as it is 
bright red, and thickly beset with long sharp prickles. 
One of the hardiest and best grow ing of the new Roses, 
Rosa bella, raised at the Arboretum from seeds collected 
by Purdom in northern China, is a plant which when 
better known will be jiopular. It is a large shrub with 
bright red flowers an inch and a half in diameter, and 
showy red fruit. The only plant in the collection is with 
the other Chiense Boses on Bussey Hill. Unfortunately 
the flowers were ruined as they opened by the excessive 
heat. Rosa multiflora cathayensis is again covered w ith 
its great clusters of pink flowers and expanding flower- 
buds. The Chinese representatives of the white-flowered 
R. multiflora of Japan, it is one of the most beautiful 
Boses of its class, and interesting as the wild type from 
which the Chinese derived the now- well known Crimson 
Rambler Bose and another old-fashioned garden plant, 
the Seven Sisters Bose {Rosa mulliflora platyphglla). 
Rosa Helenae, which some persons consider the hand¬ 
somest of the Boses discovered by Wilson in western 
China, will be in flower again in a few' days. It is a large 
shrub with slender arching stems furnished sparingly 
with small red spines and many-flowered clusters of pure 
white delicately fragrant flowers an inch and a quarter 
in diameter. It well deserves a place in any collection of 
single-flowered Boses, however small.
