The Color Wheel Garden is a large circular garden (stretching 70 feet across) situated at the street entrance to the County office building.  The garden is planted in 6 sections to represent the colors in the artist’s color wheel or the bands of the rainbow:  Red-Orange-Yellow-Green-Blue-Indigo-Violet.  There is no other garden like it in the Madison area.   A tall bur oak tree stands in the middle of the circle. Click on the following link for a video of the Color Wheel Garden in bloom:  Color Wheel Garden Video

The Color Wheel Garden has been traditionally planted entirely with annuals. In 2017, the 86 varieties of approximately 850 annual plants created a spectacular effect, with taller annuals planted near the middle of the circle and trailing vines spilling over the perimeter. In 2018, perennials that are long-blooming and/or contain continuous color in their foliage will be added. The goal is to have perennials ultimately comprise one-third of plantings within each of the 6 garden sections.  The addition of perennials will also increase the garden’s appeal in spring, before the annual plants get underway.  In 2018, a path will be installed around the perimeter of the garden to make it more accessible for viewing.

Color Wheel Garden Team
Team members are inspired by the planting combinations used in the Color Wheel Garden for possible inclusion in future gardening projects.  They learn about many varieties they may not have seen before.  In addition, team members learn about spacing requirements for the species being planted, direct sowing of annuals, proper planting techniques of seedlings, watering requirements, dead-heading, fertilizing, mulching, etc.

Sally Averkamp and Denise Tully are co-leaders for the Color Wheel Garden in 2018.  Sally is responsible for the current design of the garden and has been a team leader since 2016.  
She became a certified Master Gardener in Des Moines, Iowa in 1989 and immediately began specializing in public gardens.  She has designed multiple public gardens each year since then, drawing on her skills as a graphic designer.  As a Project Leader for the Discovery Gardens at the Iowa State Fairgrounds, their team won a “Search for Excellence” award at the Tri-State Master Gardener Conference in 1997.  After moving to Madison with her family in late 1997, Sally began working as Project Leader for the City-County gardens on Martin Luther King Boulevard and has been managing the gardens with a team of volunteers for the past 20 years.  Denise Tully completed her Master Gardener training in 2017 and was part of the Color Wheel Garden team that year.  Much of her gardening know-how is based on networking with friends, research, and trial and error.  For over 25 years, Denise has been starting the majority of vegetable and flower plants from seed for her garden and friends' gardens. House plants are plentiful in her home. 

A special thanks to Master Gardener Volunteers Jim Goodno and Dean Smith, who maintained the Color Wheel Garden over a period of 7 years upon receiving their training in 2008.  Their commitment to this garden over all those years is greatly appreciated, and serves as a model for the Adopt-a-Garden program established in 2016.
