The Iris That Seem To 
SUSIANA (Mourning Bride Iris) + $3.00; 3 for $8.25 
This amazing Iris from the Holy Land has been a sensation wherever seen. It is enchanting, wondrous, 
may always be counted on to bring forth exclamations of amazement and delight. The flower is simply 
enormous. Startling effect is of a marvelous color symphony in silvery white and black. An abundant 
producer of pollen. One of the parents of Luna and Fair Enough. Quite hardy, but may need some pro- 
tection in coldest areas. If you can’t make your neighbors Oh! and Ah! with this, they’re hopeless. 
The enormous demand |’ve had for Susiana has almost exhausted all available stocks both in this 
country and abroad. | have a few hundred available for early orders but cannot tell at this early date if 
| will be able to import enough to last all through the season. Many hundreds of my customers ordered 
Susiana too late last year after my supply was exhausted. For exhibition purposes Susiana is superb. | 
sent it to my friend Fisher Harris in Salt Lake City, in the region where cattle died of cold and snow. 
Susiana was grown out of doors. In spite of very severe winter, it bloomed finely. He entered it in the 
Utah Iris Society’s show. | quote his report verbatim, plus comments of other enthusiasts: 
"Tt is an understatement to say that Sustana ‘stole the show.’ We had several thousand visitors, no 
more than a dozen of whom had ever seen Susiana or any other pure Onco. The result was that she not only 
stole the show, but, at times and almost literally sh ie tt, for—though she was placed next to the Queen 
(for which title she was not eligible)—no one saw the poor Queen. Instead, the aisle was blocked by those 
delighted and astonished at the exotic beauty of the almost incredible Susiana, Believe it or not, she was a 
full seven inches in diameter.” 
"T planted Susiana and it was beside the front porch and the temperature was 18° below about one 
foot above it, and it bloomed. I got such a thrill I made my mind up to have some more. I call it the jewel 
of my garden.”’ Mrs. G. R. White, Farmington, Michigan. 
“T have wonderful luck using Sustana as a house plant.” Mrs. J. C. Allison, Waddington, New York. 
“T was very pleased with the Iris I received last fall. Susiana was planted outside and had a lovely 
bloom this sbring—was the talk of the country.’’ Mrs. F. Foote, Duncan, British Columbia.

You Need My New 
Manual offered on page 17. 
Since | offer such a wide variety of Iris of 20 distinct types, and having somewhat different cultural re- 
quirements, there has arisen a persistent demand for this comprehensive new MANUAL adequately 
covering the whole subject. In spite of the diversity of types of Iris, their culture is remarkably simple 
and easy to understand, as I have grouped them all under three general cultural procedures, with only 
minor special consideration in the handling of specific types. 
| have brought together for you in concentrated, verified form, a summary of my own accumulated 
experiences and those of many of my customers in dozens of different states. To this has been added 
valuable information from well over 100 books, bulletins and articles on Iris growing and hybridizing. In 
this way you can have practically everything you need to know, instantly available in one place without 
extensive searching, and without the expense of buying many different reference works. Included, for 
example, is various material directly from two of the most significant of all published works on Iris, 
namely, W. R. Dyke’s “Handbook of Garden Irises’ and his monumental work “The Genus Iris.” The 
latter is valued, when obtainable, at about $100 a copy. 
The second half of this 44 page booklet covers all phases of hybridizing from planning your crosses to 
the techniques for pollinating, seed collection and seed sowing—for Tall Bearded Iris and also the many 
Unusual Iris offered in this catalog. Among the many subjects covered are these: Varieties recommended 
as parents in breeding for 26 specific objectives; How to synchronize blooming periods; Chromosome 
numbers; Mendelian inheritance; Ways to increase your sets.

wholly complete and up-to-date for very long. Hence | propose to issue, from time to time, a series of

terest. The following partial outline will give a good idea of the comprehensive contents of Supplement

of blooming seasons and heights.
