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 sq 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, welbdrained 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, 
single divisions, and we always send 
out the best plants available. It should 
be understood that while we strongly 
advise planting in July and August, 
the plants are not as large or well 
developed as they are in the fall, but 
it is to your advantage to have the 
plants make their growth in your gar¬ 
den rather than in our own. For 
southern states, better results might be 
obtained if Irises are planted in Sep¬ 
tember 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 United States only. 
A Few Remarks 
About Iris Rot 
Please Read Carefully. 
The development of root rot in 
bearded Iris is a condition that at 
times all Iris growers have to contend 
with. Some of the causes of this con¬ 
dition 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 with¬ 
out 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 
rotted parts, sprinkle with powdered 
sulphur, let the sun shine on the rhi¬ 
zome 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 Florticultural Society at 
the Northwestern National Bank 
Building, we made twenty-three en¬ 
tries and won twenty-one prizes, four¬ 
teen firsts, six seconds and one third, 
besides the Sweepstakes for the most 
prize points scored, and this silver 
loving cup for the most comprehen¬ 
sive 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 in 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.
