A GUIDE to the Selection of PRES for Your Garden of Enchantment 
Rare and unusual types, from ’round the world, to bring new interest to your garden 
Below you will find the data you need in choosing varieties and types of Iris for various seasons and for different parts of your garden. Thus these listings will give you hints 
as to culture, but are not intended to replace cultural directions, which are given very briefly at the beginning of each section in this catalog, and ever so much more fully in my 
RAINBOW IRIS MANUAL. Many Iris have a wide latitude of tolerance, and it is not to be inferred that they will succeed only under the conditions indicated. I have broadened 
these IRIS SELECTORS out beyond my current offerings, but each year I will have more kinds for you. My INDEX (page 31) will show where to find the 500 kinds offered this 
year. I have used the symbol © to mark those I do not have, or that I have too few to catalog. If you have any of these, or know of a source of plants or seeds, won’t you please 
write me? I hope you find this page helpful.
