Keller will explain the garden's evolution and its many distinctive features.
Eight acres of marsh, woodland, meadow and vegetable plots coalesce to form the Garden of Ideas. An arboretum-like collection of plants can be found amid a unique array of original garden art.
The garden was conceived and is maintained to create spaces, grow interesting plants well, minimize unnecessary landscape maintenance, provide animal habitats and produce nutrient-dense food crops.
The meeting begins with a coffee social at 9 a.m. Admission is free.
