6 Veans OF 
... TELL THE FACTS OF WHY YOU SHOULD 
We have been doing just a single thing—raising nursery stock— 
for so long, that we’ve been taking ourselves for granted! We even took 
our customers for granted—believed that they were pretty familiar with 
the reasons Naperville could give them good, satisfactory nursery stock. 
But with the announcement in 1941 of our 75th Year Diamond 
Anniversary, So many of you stopped in to talk “old times’’ that we were 
surprised by all the important things we had come to consider common- 
place. We owe you thanks for your interest, and the awareness you 
brought to us that our old-fashioned, unhurried methods are still the 
only way to produce the best nursery stock. 
Naperville is a HARDY Nursery 
Naperville stock will transplant more suc- 
cessfully to your customer’s location—be- 
cause it is grown in one of the severest 
winter-kill regions in the U. S. 
Chicagoland always has 10 and 20 be- 
low zero weather every winter—anything 
that is going to winter-kill is killed in our 
nursery row. Here, too, we really have 
thaws—in January and February temper- 
atures go up and down 35 degrees in a 
day or two, breeding-in a hardiness pos- 
sible in few other places. 
Transplants Only—at Naperville 
We use no short-cut, quick-effect or so- 
called ‘‘just as good’’ methods at Naper- 
ville. Every item gets the kind of care 
it needs to insure best development. 
No item is considered salable until it 
has been in the field 3 years. Every item 
in this catalog has been both root-pruned 
and transplanted at least once. 
Heavier Tops—More Fiberous Roots 
Naperville’s transplanting program re- 
tards tap-rooting, promotes compact, fi- 
berous root growth. Such stock is moved 
more successfully, without undue set back. 
This program also results in better ma- 
tured, denser tops, that make substantial, 
finished specimens. 
Usual “‘height’’ method of pricing gives 
only a partial idea of Naperville’s values. 
That’s why we .state number of canes on 
many items, use photo’s on some pages, 
to show you what to expect. 
‘Pedigree’. Propagating 
Naperville does not buy _ lining-out- 
stock. We produce our own cuttings and 
seedlings. Large mother-blocks are main- 
tained so that we control type, vigor, 
bloom, color, size, hardiness. 
Our mother blocks are made up of 
individually selected, maturity-proved 
plants that have been chosen over years 
of culling. When improved items are de- 
veloped elsewhere, we buy young plants, 
which must grow and bloom in our nur- 
sery before use as mother stock. This 
costlier program insures you of predict- 
able satisfaction every time. 
Fresh Dug for Your Order 
Naperville does not dig in the fall and 
store ‘‘dormant’”’ over winter. All items 
in this catalog are dug individually for 
each order. While this method costs us 
more, Naperville prices are no_ higher. 
We believe it gives you hardier stock, 
better livability. 
1942 was a “Vintage Year” 
Here at Naperville we had one of the 
best growing seasons in a decade. Our 
rainfall was one of the heaviest in the 
history of the weather bureau. In ad- 
dition, temperatures were mild—spring 
opened up earlier and was warmer, while 
summer was cooler. 
Everything in our nursery made heavier 
grades within sizes. Tops filled out more, 
were denser. Visit us this year, and see 
these heavier Naperville specimens.
