YOU ARE CORDIALLY INVITED 
to visit us and see our show fields in bloom, especially during the 
month cf May. Thousands of Iris friends marvel every year at the 
color display of hundreds of Iris varieties in bloom. This year we 
shall have many not offered before. 
THE NATIONAL IRIS GARDENS are located on the Canyon Road, 
one mile east of Beaverton, Oregon, and five miles west of Port- 
land. We are fortunate to have our Iris gardens in the Pacific 
Northwest, both in Oregon and Washington. Our climate is mild 
with plenty of moisture and a long growing season which enables 
the Iris roots to grow and develop especially well, with just 
enough of winter each year to make Northwest grown Iris as per- 
fectly hardy as those grown in the northernmost and easternmost 
states. 
We send detailed planting instructions with each order.
