A Zone Map for Mean Annual Moisture Balance in the North Central United StatesLandscape Plant News
Publication VersionPublished Version
AbstractThere are many climatic factors that can limit the adaptation of woody landscape plants. In the North Central United States, one of the most widely studied limiting factors is winter injury caused by low temperatures. Mean annual minimum temperature is the basis for the USDA Plant Hardiness Zone Map (Cathey, 1990), which is perhaps the most well-known guide for defining woody plant adaptation in the region.
