Macmillan, New York. For example, the 4 to 5 C (7.2 to 9 F) standard deviation near Chelan (zone 7a) translates into 1 year in 8 to 12 years likely to experience temperatures typical of zone 6a (Table 4), which would pose only a minimal risk from killing freezes for most grape cultivars. The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. In addition, it also is important to recognize and account for important modifying factors. One or more long-term evaluation sites should be established within the Black Hills to incorporate this unusual climatic region into the NC7 Regional Ornamental Plant Trials and begin testing hypotheses about the climatic determinants of woody-plant adaptation. Zone 11 was introduced to represent areas with PH > 4.4 C (40 F) that are essentially frost-free. Nonetheless, they decided to retain the existing system because of its widespread adoption, including the availability of estimates of winterhardiness based on the PH statistic for thousands of plants [three online examples include the NGA Plant Finder (National Gardening Association, 2010), Cornell University's Flower Growing Guides (Cornell University, 2006), and the UConn Plant Database (Brand, 2001)] and the assortment of compatible hardiness-zone maps available internationally.

USDA Unveils New Plant Hardiness Zone Map By Kim Kaplan January 25, 2012 WASHINGTONThe U.S. Department of Agriculture (USDA) today released the new version of its Plant Hardiness Zone Map (PHZM), updating a useful tool for gardeners and researchers for the first time since 1990 with greater accuracy and detail. In: Sunset western garden book, new century ed. These are an abbreviated growing season, with freezes possible in any month, and rapid, strong fluctuations in winter temperatures (National Oceanic and Atmospheric Administration, 1980), which, when they occur on both sides of the freezing point, can initiate drastic dehardening and cause winter injury. Vol. zonemap : USDA ARS - Agricultural Research Service For instance, the average annual minimum temperature for zone one is -50 to -60 degrees F. or -51.1 to -45.6 degrees C. Since that time USDA Hardiness Zone map changes have included the addition of zones 11-13. (2008) for a detailed discussion of the Spring 2007 freeze in the eastern and central United States], but such weather events are not repeatable and do not lend themselves to experimentation and hypothesis testing. Users may also simply type in a ZIP Code and find the hardiness zone for that area.
