The highest award an LA could receive from 1948 until 1985 was the Mary Swords DeBaillon Award. During that period, SLI was an independent unit with no affiliation whatsoever with the American Iris Society (AIS). SLI became a Cooperating Organization of AIS in 1986.

After that date the AWARD was discontinued and replaced with the Mary Swords DeBallion MEDAL, the highest award exclusively for Louisiana Iris. The MEDAL is a part of the AIS award system. All AIS medalists, including the Debaillon medalist, are elegible for the Dykes Medal, the highest award presented by AIS. So far, the AIS Dykes has only been awarded to Tall Bearded iris and Brown Lasso, a Border Bearded iris.
