Selecting Trees for Cold Climates    (View PDF)

Harold Pellett

Abstract: Lack of sufficient tolerance to low temperatures is often a limiting factor for successful use of many woody plant taxa in cold climates. Trees capable of acclimating to withstand the lowest midwinter temperatures may still perish if they do not acclimate early enough to withstand severe freezing temperatures in early winter. The University of Minnesota has introduced several tree cultivars selected for their winter hardiness. Merits of these introductions and other plants that have shown potential for use in Minnesota and other northern areas are described in this paper. The goals and activities of the Center for Development of Hardy Landscape Plants are also briefly discussed.
