A lifetime spent protecting one of the world’s most beloved flowers has earned a University of Tennessee researcher the highest honor presented by the American Rose Society.

Mark Windham, professor emeritus in the University of Tennessee Institute of Agriculture’s Department of Entomology and Plant Pathology, received the society’s Gold Honor Medal on Oct. 3 during its 2026 National Convention and Rose Show in Nashville.

The award recognizes decades of research, education and service devoted to helping gardeners and commercial growers keep roses healthy.

Windham joined UT in 1985 and became a nationally recognized authority on rose diseases, including black spot, Cercospora leaf spot, downy mildew and rose rosette disease. His work helped growers better understand how to identify, prevent and manage diseases that threaten rose gardens across the country.

“When I think of the great rosarians who have won the medal, I am beyond honored to join them in this distinction,” Windham said. “It’s a privilege to have worked for UTIA as long as I did, and I want to thank the countless colleagues, mentors and collaborators who made this possible.”

Much of Windham’s research was conducted at UT’s Plateau AgResearch and Education Center in Crossville, where his work helped establish the facility as a leader in rose disease research.

In 2018, Windham collaborated with fellow Extension plant pathologist Alan Windham and other researchers to publish A Guide to Rose Diseases and Their Management, providing practical information for growers and home gardeners.

Both researchers retired in 2022 but have continued supporting rose production and education throughout the Southeast.

Hongwei Xin, dean of UT AgResearch, credited Windham’s research with helping establish the Plateau center’s national reputation.

The Gold Honor Medal is the American Rose Society’s highest award, recognizing exceptional service and contributions to rose cultivation and education.

Windham also received the society’s Joseph and Marion Kilma Medal for Excellence in Rose Education in 2023, making him one of the few individuals to receive both honors.

For East Tennessee gardeners, his legacy is found not only in scientific publications but also in healthier roses growing in gardens throughout the region.
