Is This Plant Hardy in Your 
Gardenf 
The map marks off num¬ 
bered zones from I to VII, 
each zone being a section 
of the country with approx¬ 
imately equal climate con¬ 
ditions. As names and des¬ 
criptions are listed in the 
Short Guide you will find a 
Roman Numeral after each 
one. This numeral indicates 
the northernmost zone in 
which that tree or shrub is 
hardy. If in brackets (V), 
the meaning is that protec¬ 
tion is required in the Win¬ 
ter months. The informa¬ 
tion upon which this map is 
based is from Dr. Alfred 
Rehder’s Manual, described 
below. *(MacMillan Co.). 
It is impossible to cover all 
the details in a small map. 
Many factors besides cli¬ 
mate affect a tree’s growth. 
If in doubt, write us and we 
will endeavor to give more 
detailed information for 
your particular locality.
