The Queen Garnet plum is the spectacular result of an early 2000's stone fruit breeding program in Queensland: when the plums were fed to obese rats, there was a stunning turnaround in their health.

The entertaining program is family-friendly and educational will be at 1 p.m. at the Helen Plum Memorial Library, 411 S. Main St. For information, call (630) 627-0316 or visit www.helenplum.org .
