The Founders of SIGNA Medal is the highest special medal awarded by the American Iris Society to species irises. The candidates are the species irises that have received the Award of Merit 2, 3, or 4 years ago. The winners of the medal are then among those eligible for the American Dykes Medal the following three years.
Here are the five candidate species irises on the 2015 ballot.
