Debaillon Award and Debaillon Medal Detailed Results (runnerups in the voting are also included)

The DeBaillon Medal is awarded each year to the Louisiana iris receiving the most votes from the American Iris Society (AIS) judges and is awarded by AIS at the annual convention. To become eligible for this award, an iris must have received the Award of Merit (AM) in its class.  Eligibility begins the second year after the variety has received the AM and continues for a period of three years. This article shows MSDM winners from 2021 to 1948 and gives the number of judges' votes received as well as the "runnersups" for each year they were recorded.

Marie Caillet and Rita Hickerson


Since 1948, the DeBaillon Medal, given by the American Iris Society, has been the most prestigious honor a Louisiana Iris hybridizer can receive.  The Author traces the award's history, triumphs, and controversies.

Marie Caillet spent a lifetime promoting the Louisiana Iris, first while a resident of Lafayette, LA, where she taught at the local university, and after her retirement at her family home on Lake Lewis north of Dallas, TX.  She served the Society for Louisiana Irises in many capacities, including editing the journal for decades.  She was 92 when she died on May 20th, 2010.


Each year the American Iris Society (AIS) judges to award the Award of Merit (AM) to a group of irises.  Eligibility for the AM beings the second year after the iris variety has recieved the Honorable Mention Award (HM), and eligibility continues for three years.

The AM is one of the AIS's most coveted awards and is given each year to a limited number of iris varieties in each of the classifications of iris.*

SOCIETY FOR LOUISIANA IRISES -- Mary Swords DeBaillion Awards --- 1948 to present

The highest award an Louisiana iris 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 and in 2012 became a section of AIS. After 1986 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 and is awarded to the eligible Louisiana iris receiving the most votes on the official AIS judges' ballot conducted each year. All AIS medalists, including the DeBaillon medalist, are eligible for the Dykes Medal, the highest award presented by AIS. So far, the AIS Dykes has been awarded mainly to Tall Bearded irises and no Louisiana iris has ever won the Dykes award.

I have seen Louisiana irises come and go for more than 50 years. I have seen not-so-good ones make it to the top and then disappear from gardens. But worse than that are the really excellent varieties that have never received awards nor become generally known. What makes the difference and what can a hybridizer do to elevate these good ones from the ordinary to the winner's circle? Nothing I am going to suggest will be news to you and some solutions will not be possible, but perhaps one or two will give you an idea. Each are things I have observed and some are things I know have worked for some Louisiana iris winners in the past.
