Pfeiffer's IRIS 
Duenjone I^oues 
Pfeiffer’s Iris 
Irises are undoubtedly one of the most popular 
of all the hardy perennials. No other perennial 
plant available to our gardens combines so many 
good qualities. They are inexpensive, extremely 
hardy, may be grown under a great variety of 
conditions with a minimum amount of care, and 
they have a wonderful range of colors from the 
lightest pale yellow to rich gold and deep bronze, 
delicate pale blues, and lavenders to dark blue 
and violet to deepest purple, light pink to claret 
and deep maroon, all the shades of lavender, 
mauve, violet and pure white, with an endless 
array of combination colors.

Extra Fine Varieties 
at Moderate Prices 
Irises are of easy culture and can be planted 
almost any time the ground is not frozen. They 
will do best in a sunny, well drained location in 
a medium loose, mellow soil. Irises must be 
planted shallow; many people plant too deep 
and the plants rot. The rhizome or fleshy part of 
the root should be just under the surface of the 
ground. If your location is a low spot where 
water will stand, it is advisable to make raised 
beds, so the water cannot stand around the roots. 
Good drainage is necessary. If the soil is sour, 
an application of hydrated lime is advisable. 
Never use manure. 
A Word About Plants 
and Prices 
Our prices are based on strong, sin¬ 
gle divisions, and we always send out 
the best plants available. It should be 
understood that while we strongly ad¬ 
vise planting in July and August, the 
plants are not as large or well devel¬ 
oped as they are in the fall, but it is 
to your advantage to have the plants 
make their growth in your garden rath- . 
er than in our own. For southern 
states, better results might be obtained 
if Irises are planted in September or 
October. 
Mass Planting Advisable 
An Iris display in the garden is 
much more effective if they are plant¬ 
ed in groups of from three to a dozen 
plants of each variety, and to stimulate 
an interest for mass planting, we are 
making attractively low prices by the 
dozen on many varieties. 
Collections 
Largely for the benefit of the be¬ 
ginner in Iris growing we are offering 
some exceptional collections and com¬ 
binations listed on another page. For 
the Iris fancier who wants the best and 
knows just what he or she wants, we 
have a list of varieties that will appeal 
to you. 
Guarantee 
All plants are guaranteed to be true 
to name, vigorous and healthy when 
received. If found to be otherwise, we 
will either replace with true stock or 
refund your money. Mistakes are 
made, but not intentionally. 
Prices include prepayment of post¬ 
age in the Ihffted States only. 
A Few Remarks About 
Iris Rot 
Please Read Carefully 
The development of root rot in beard¬ 
ed Iris is a condition that at times 
all Iris growers have to contend with. 
Some of the causes of this condition 
are too deep planting of the rhizomes, 
especially early in the spring, water 
standing around the plants, hot and 
humid atmosphere, abnormal cold 
weather in winter without any snow- 
protection. 
THE REMEDY: Make raised beds 
or ridges, so water cannot stand 
around the plants, plant very shallow, 
the top of the rhizome should be at the 
surface of the ground. Next, if rot 
should develop, scrape the soil from 
around the rhizome, clean out the rot¬ 
ted parts, sprinkle with powdered sul¬ 
phur. let the sun shine on the rhizome 
and you will soon be rid of rot. 
A light covering of straw or coarse 
hay put on after the ground freezes, 
will help to carry your plants safely 
through the winter. 
Follow above instructions and you 
will have little, if any, trouble with rot. 
Prize-Winning Irises 
The quality of our plants is unsur¬ 
passed. At the Minneapolis Iris Show- 
held in Minneapolis. June 2nd and 
3rd. 1932. under the auspices of the 
Minnesota Horticultural Society at 
the Northwestern National Bank Build¬ 
ing. we made twenty-three entries and 
won twenty-one prizes, fourteen firsts, 
six seconds and one third, besides the 
Sweepstakes for the most prize points 
scored, and this silver loving cup for 
the most comprehensive display at the 
show. This we did after carrying the 
flowers 143 miles in an automobile. 
When you get plants from Pfeiffer’s 
you get these prize winning strains at 
no additional cost to you. 
HOW TO PLANT 
IRIS ROOTS 
Set plants on light, well 
drained soil where water will 
not stand. The rhizome or 
fleshy part of the root should 
be at the ground level. If soil 
is sour, ground limestone is 
beneficial. Use no fertilizer.
