Since 2011, Biltmore Estate has run international rose trials where rose breeders and growers submit new roses for a two-year trial. Winning roses from the trials are considered to be some of the best roses in the world. Dr. Mark Windham has been invited to become a permanent judge for the International Jury for the Biltmore International Rose Trials competition. Additionally, he has been selected to participate in the annual formal international judging, which is attended by rose enthusiasts from across the globe. These invitations are a very big honor in the “rose world.” Dr. Windham was not chosen for his ability to grow roses (very modest skills at best), but for his ongoing research on rose diseases and for his recent guide on rose diseases.
