Northern Research and Demonstration Farm
Home demonstration gardens were located at nine sites across the state. The objective was to grow, display, and compare a wide variety of vegetables and flowers. Some of the themes for the 2006 garden included a plethora of peppers, unusual green melons, geraniums, ornamental pigweed, and a food guide pyramid garden.
