One of the iris resources you should be aware of and use is the Region 21 Library. There are a variety of Iris books, AIS and Region 21 Bulletins, Median Iris Society Bulletins, and several iris tapes. The photo at the left shows our holdings as of a few years ago. (If you would like a print of this, here is the Region21Library PDF.) Our most recent acquisition is the Kelly Norris book A Guide to Bearded Irises: Cultivating the Rainbow for Beginners and Enthusiasts
[Update February 20, 2017: You can find the Region 21 Library updated holdings on the Resources page. Contact information to check out items is now Wayne Messer, firstname.lastname@example.org or see Issue 148 Region 21 Bulletin for additional contact information.]
Note that the Region pays for the shipping of these items.
