The Hans and Jacob Sass Medal is the highest special medal awarded by the American Iris Society to intermediate bearded (IB) irises. The candidates are the IBs that have received the Award of Merit in the previous three years. The winners of the medal are then among those eligible for the American Dykes Medal the following three years.
Here are the four candidate IB irises on the 2015 ballot.
