The Burdick-Craddick-Lott Walk displays 81 varieties of chrysanthemum (Chrysanthemum sp.) of which 26 are introductions by the Department of Horticultural Science, University of Minnesota. Look for the maroon labels to find the U of M introductions. Chrysanthemums or ‘mums' are great garden perennials as they bloom late in the season when few other perennials are in bloom and they come in a wide range of colors and flower forms. The U of M introductions all bloom early enough to avoid frost damage.
