Johnson County Fair Grounds

Butterfly House. MG share information with the public about native butterflies’ life cycles, habitats, and provide educational gardening material that benefits butterflies and other pollinators.

Demonstration Garden. MG showcase their planting and design skills in the “Demo” Garden at the Johnson County Fairgrounds. The garden was organized in 1993 in a partnership with the Johnson County Agricultural Association (JCAA).

Fairgrounds Flower Beds. MG design, create and maintain the flower gardens that dot the Johnson County Fairgrounds landscape.

Rain Garden. A living memorial was established in memory of Ruth & Ken Wagner and Martha & Everett Winborn for their commitment to environmental education in association with the Soil & Water Conservation Districts. Utilizing a shallow depression, the Rain Garden collects and holds rainwater for a short time allowing water to slowly seep into the ground. Rain Gardens help filter pollutants and provide food and shelter for butterflies, songbirds, and other wildlife.

Hospice Gardens

In 2003, Project GREEN, Iowa City Hospice, Iowa City businessman Casey Cook, and the City of Iowa City launched the garden that offers a respite and quiet reflection.
