A new butterfly garden at a historic site in Springfield will be the setting for a talk by a biologist and gardening expert.

Susan Dees-Hargrove will share her experience gardening for moths and butterflies on Sunday afternoon at the Dana-Thomas House State Historic Site.

She's a biologist with the Illinois Department of Transportation and specializes in endangered species and wildlife habitats.

The Dana-Thomas House in Springfield was designed by Frank Lloyd Wright in 1902. The site has a new butterfly garden installed by volunteers at the White Cottage, next door to the house. University of Illinois Extension Master Gardener volunteers will talk to visitors about the plants.

Admission is free and light refreshments will be served.
