Discover The Fascination of ONCOBREDS or Onco-Bearded Hybrids 
The Appeal of the 
ORIGIN and NOMENCLATURE: Diverse names have been used for this class of wonderful hybrids 
of Oncos with Bearded Iris, but Clarence White’s apt term ‘‘Oncobreds” is simplest and best. They 
have been called Pogocyclus, Eupogocyclus and Oncopogons. 
MOHRS: Except for “Frieda Mohr,” all of the large and ever-increasing family of Mohrs belong in this 
category, as they all contain both Onco and Bearded blood, and are descendants of the original “William 
Mohr.” See my special Mohr collections. 
CHARACTERISTICS and USES: As compared with the familiar Tall Bearded Iris, these Oncobreds 
stand out as being highly distinctive and different. They have an amazing array of novel color 
patterns, some of which are just out of this world. Due to their Onco ancestry, many have broad rounded 
form surpassing even the newest and finest in Tall Bearded Iris. | have for years been predicting a 
RAINBOW OF ONCOBREDS and now this is being unveiled before your eyes. Below are the world’s 
most complete offerings in this line—not just the original purples and lavenders from a few breeders, 
but varieties from 24 hybridizers, distributed through 13 DISTINCT COLOR AND PATTERN CLASSES. 
You should have at least one or two in each class to really understand what the new Oncobreds can do 
for your garden. 
EXPRESSION OF ONCO CHARACTERS: Oncobreds vary greatly in the degree to which they exhibit 
externally the Onco that is in their genetic makeup. Some resemble true Oncos fairly closely, while in 
others there is no visible evidence of Onco characteristics. Yet the presence of an Onco in the genealogy 
should make them easier to cross with Arils, and other Oncobreds. The newer and finer Oncobreds are 
getting closer and closer to the alluring fascination of true Oncos, and are easier to grow. 
BLOOMING TIMES: Vary greatly, from late March to early June, according to variety. 
CULTURE and HARDINESS: The great majority of these have inherited the sturdiness of the Bearded 
Iris and can easily be grown as explained for Tall Bearded on page 21. A few are strongly Onco-like and 
are better handled a little more like Arils (page 4). 
SHIPPING and PLANTING TIMES: Summer and fall, like Bearded Iris.

Strange MARBLED and MULTICOLORED Effects 
JOPPA PARROT (White '48) 4% $7.50 
Most startling, bizarre Iris in the whole array of colorful Oncobreds! Clarence White has 
used Oncos to produce many strange color combinations bordering on tage unbelievable, 
but never one like Joppa Parrot. Standards fully rounded, cupped, Onco-like, light mauve, 
heavily, irregularly streaked and lightly veined soft mulberry. Falls rounded, strongly 
convex in Onco fashion, bronzy gold, with an intricate pattern of cinnamon-red and yellow, 
exploding into bold streaks of mulberry black. Beard also Onco-like, very broad, promi- 
nent, golden bronze. Style crests yellow-buff contrasting wonderfully with mauve stand- 
ards. Superb for seekers of the unusual, and for hybridizers. One of the 3 most potent & 
useful Oncobred pollen parents known. Among its diverse offspring are exciting color- 
breaks from chartreuse yellow to dark olive-green, veined in red. Onco-like, so be sure 
to provide good drainage, winter mulching in cold regions. Judging by last year’s sales, 
my stock is only a fraction of enough to meet '53 demand; order TODAY if you want this.
