The Elizabeth Carr Slade Perennial Garden is a delightful garden in a formal parterre. The central pool and fountain is surrounded by plantings of blue and gray foliage and flower to enhance the blueness of the water. This is then surrounded by four quadrants of grass with walks dividing the grass from the oval shaped perennial border. It gives the user many ideas about plant combinations as well as how well the plants grow in Minnesota. There are 137 genera, 324 species and cultivars in this garden.
