“If We List It, It's Good" 
In addition to offering the finest stock, 
we list only the very best varieties ob¬ 
tainable. We receive yearly reports from 
many iris experts, and buy those most 
highly recommended. These we grow in 
our garden until we have blooms for com¬ 
parison to our other iris. Only those 
that are distinct and come up to our 
standard are offered in our catalog. The 
others are discarded. 
“EXTRA ENERGY". . . 
Our stock is ideally grown, for our climate and 
location produces the healthiest, most responsive 
rhizomes possible. Our gentle sloping hillside loca¬ 
tion gives us the fine drainage that makes firm, 
hardy rhizomes; and our climate adds to your 
assurance of vigorous stock—for the mild winter 
and early spring give our plants a healthy growth 
early in the season, and the fact that we have no 
summer rains matures our rhizomes perfectly— 
ready to withstand the rigors of the most severe 
climates. 
Better results from our stock are actually 
shown by the following statements from our 
customers: From Iowa—“I want to let you know 
that every iris I bought from you ... is alive and 
doing just fine—in fact making better growth than 
those bought in this part of the Mid-West”; and 
from New York, comparing the growth of Mid- 
Western and Eastern rhizomes with that from ours: 
“Your California grown iris . . . gave more certainty 
of blooms the first year after planting, due to the 
extra stored up energy in a well grown root.”

FOR NEXT YEAR 
We feel that our new introductions for 1937 will again form 
the finest set ever introduced by one firm—eclipsing even the 
previous high standards we set by our introduction groups of 
1927 and 1934 (approached in 1935 and again this year). Two 
sensational varieties of our own, and several more outstanding 
seedlings from the gardens of Sydney B. Mitchell and Edward O. 
Essig form a tentative list of top-notch new iris—any one of which 
would be worthy of a lead position among any groups of iris 
introductions.
