NEW ITEMS 
We are continually dropping common lines and con- 
centrating on novelties and specialties. These are the 
things that are always in demand, hence this list is well 
worth very careful study if you take interest in trees and 
shrubs which are out of the ordinary. : 
During the last 13 or 14 years we have doubtless im- 
ported the greatest assortment of new and rare woody 
plants brought into the country during that period. Evi- 
dence that our efforts have been successful is that in 
1945 our senior partner was awarded the Jackson Dawson 
Memorial Gold Medal by the Massachusetts Horticultural 
Society “for making many new woody plants available to 
American gardens.” 
About 1931 we started a program of breeding woody 
ornamentals, mainly Lilacs, Flowering Quinces, Peaches 
and Apricots (Prunus mume). This work is very slow 
but we feel that results have amply justified the time 
devoted to it. 
Several items originated by us are now being intro- 
duced on an exclusive basis by certain first-class retail 
catalog houses who wish “leaders” of high quality. We 
have a few more of these items available and shall be 
glad to explain the arrangement on request. 
EXPLANATION OF HARDINESS RATING 
As this list goes all over the U. S. A. and also abroad, 
we believe it a good idea to indicate hardiness. This has 
been done by. giving after the name of each item a num- 
ber in ( ) indicating the zone up to which it is considered 
hardy. 
Our authority through Zone 7 is Rehder’s Handbook. 
For Zones 8 to 10 we have been guided by Pacific Coast 
experience and have subdivided Zone 9 so that 
(9) indicates probably safe to 20° (Sacramento and 
San Joaquin Valleys, etc.). 
(914) indicates probably safe to 25° or 26° (San Fran- 
cisco Bay Region, etc.). ) 
(10) indicates will stand only very light frost. 
To find the zone you are in refer to map on center 
pages of this book, which we use by the courtesy of 
Arnold Arboretum and McGraw-Hill Book Co. 
We hope this innovation will be helpful to nurserymen 
all over the country. Please understand that ratings show 
our honest opinion, but we disclaim all responsibility for 
their correctness.

LINING OUT STOCK— 
For convenience, this is assembled on page 23. The 
list comprises mainly new and uncommon items, so de- 
serves careful scrutiny. 
POT GROWN AND GALLON CAN STOCK— 
We find that many customers, especially those at a 
distance, prefer to have us remove soil and ship “bare 
roots” packed in moss. If you order any of this class of 
material please be sure to say whether you want it 
packed with or without soil on the roots. 
California nurserymen will please note that 4-in. pot 
stock in body of list can be transferred at once to gallon 
cans for immediate sale, while the smaller sizes for 
growing on, together with 2% and 3-in. pot stock, will 
usually be found at end of list.
