Lilacs in the arboretum have come from all over the world. Following an age-old tradition at Eureka College, graduates who travel the globe bring back Lilacs for the Arboretum. In turn, Lilacs from the arboretum find their way to gardens throughout Eureka and across the country.
The festival is centered around the wide variety of Lilacs in the arboretum, but also includes a Fine Arts Fair, childrens' activities, community activities and other
special events.
Fine Art and Crafts of all types are on display and available for purchase during the festival. The artists and craftspeople who created the works are available to the public during the Fine Arts Fair.
The Festival is coordinated by the Walnut Grove Fine Arts Association, which takes its name from the original name of the town.
Eureka is easily found along Illinois Route 117 just seven miles north of Interstate 74 at Goodfield.
