TERMS 
Prompt attention is given to orders from both old and new customers. It is our purpose to 
give the largest measure of satisfaction in every transaction. New customers are requested 
to accompany orders with satisfactory references. To avoid delay send cash with order. 
Owing to the reduced prices we are making this year, in both high grade Peonies and Iris, no 
additional discounts are allowed. Former discounts are taken off in the prices we are now 
quoting. We always allow a generous interpretation of size of roots. 
Great care is excerised in packing for shipment, to insure safest delivery. We make no charge 
for packing. 
When shipping instructions are not given we are careful to use our own best judgment. 
TO THE TRADE: Ask for wholesale list. 
SHIPPING SEASON 
Iris can be moved any time when the ground is frozen or while blooming, but the most favorable 
time is from July first to the end of September. If set late in the fall, protect with a mulch to 
prevent heaving by the frost. 
We begin filling Peony orders about the first of September. Any Peony is much surer to bloom 
and will be twenty percent stronger if moved in September, so that new rootlets may form 
before freezing down. 
We do not ship Peony roots in the spring. 
To preserve the names make a diagram on our bill with each item numbered as planted. 
Mt. William A. Peterson will gladly give any sincere lover of Peonies and Iris the benefit of his 
years of rich experience in answer to any inquiry for information desired when explained in 
detail. This service is intended to help our customers produce best results. 
MORE ABOUT THE IRIS 
The Iris species are generally divided into three groups: First, the Bearded Iris, by far the most 
important. Though formerly called German Iris, they are not from Germany, but from the 
dry highlands of Southern Europe and Asia Minor. Second, Beardless Iris or grassy leaved Iris, 
which flourish in moist situations, include the Japanese Iris. Third, the Bulbous Iris mostly 
native to Northern Africa and Persia. Our collection is confined to the tall bearded Iris. 
Two enemies to be on the lookout for are the Iris borer and Iris root rot. The borer is a larva 
of one of the night flying moths that bites the leaf about the blooming season, and if not killed 
by pinching the leaf will soon work down into the root. Here it must be dug out and destroyed. 
Mr. W. R. Dykes, the great English authority on Iris, writes of the Iris root rot: “It is generally 
at its worst during the flowering season, when tufts of leaves will be found turning prematurely 
yellow at the tips, or stems will be discovered rotten at the base. The disease is bacterial. The 
rhizomes become rapidly soft and rotten and emit an offensive smell. 
When a plant is found attacked it should be lifted without delay. The soft portion of the 
rhizome should be carefully cut away and burned, but the sound remainder, including the roots 
and leaves, dipped into a bright pink solution of potasium parmanganate.” 
The tall bearded Iris are as beautiful in form, texture and color as orchids and many are delight¬ 
fully fragrant. 
FRAGRANCE OF THE IRIS 
The fragrance of certain Iris is very pronounced—Caprice has a very strong and decidedly grape 
juice fragrance, while Fairy is as heavily scented as a hyacinth or a tuberose.
