Harris House Backyard Garden

Come and explore this unique garden! In 1997, Guelph landscape architect, Brad Peterson, was hired to develop a landscaping plan to help naturalize this backyard. Over 16 years, he turned this site into a Carolinian forest area, a pond, vegetable garden, wetland and sauna. Areas were planted with native species, such as shagbark hickory, blue birches, elderberries, tulip and redbud.
