USDA Planting Zone Interactive Map is a tool where you input your zip code and the map will indicate the cold hardiness zone. However, many horticulturists apply hardiness zones in a prospective manner, with an expectation that past climatic records can serve to forecast current and future plant performance, as related to low-temperature damage. Academic Press, New York. 1997a Hardiness zones in China. The regression equation is SO = 0.0309 PH + 0.0048 Im + 1.2671, where SO is the overall proportion of plants surviving after 10 years, and Im is calculated following Mather and Yoshioka (1968): Im = [(annual mean precipitation/potential evapotranspiration) 1]. A 5 C (9 F) standard deviation translates into about a 13% chance (1 year in 7.6 years) that, in any given year, the PH statistic could be at least two half zones colder than the mean, and another 13% chance that it could be at least two half zones warmer (Table 4). The TRT recommended that a new PHZM incorporates the most recent and accurate meteorological data, applies the most advanced interpolation methods, and focuses only on plant cold hardiness, as measured by the PH statistic. Climate of South Dakota, p. 688703. The West's climate zones, p. 2763. Exploring the complexities of plant hardiness. 1A and B). 20 47 56, Widrlechner, M.P., Schutzki, R.E., Yukhnovsky, V.Y. 814 (revised). Decoding Planting Zones: USA Hardiness Map - Grit Returning to the Walla Walla example, with the 6 to 7 C (10.8 to 12.6 F) standard deviation that prevails in the valley (zone 7a), about one in five years can be expected to reach minimum temperatures that are characteristic for zone 6a (Table 4), and hence just marginal to avoid a killing freeze. It can be combined with other high-resolution geographic datasets for a broad range of geospatial analyses. Strong correlations between these two important climatic determinants strengthen the apparent practical value of plant hardiness zones for predicting general plant adaptation. For example, the USDA Risk Management Agency uses the USDA plant hardiness zone designations to set some crop insurance standards. Second, the more local effect of cold-air drainage and pooling, common in certain river valleys, is readily apparent. Macmillan, New York.

In contrast, the 1990 map was based on temperature data from only a 13-year period of 1974-1986. The PHZM is accessible via an interactive website, which facilitates a wide range of horticultural applications.

A lock ( U.S. Government Printing Office, Washington, DC. <. Correlations between updated Plant Hardiness Zones (Table 1; x-axis) and American Horticultural Society (AHS) Heat Zones (Cathey, 1997) (Table 3; y-axis) for three transects. Most growers expect their newly established vineyard to remain productive for 30 years or more. Horticulturists have identified three primary variables related to warm-season heat and plant adaptation: night temperature (Deal and Raulston, 1989), annual days above 30 C (86 F) [American Horticultural Society (AHS) heat zones (Cathey, 1997)], and lack of sufficient heat units (Pigott, 1981; Pigott and Huntley, 1981). Vol. Plant List of Attributes, Names, Taxonomy, and Symbols. The Cascade Range in the Pacific northwestern United States and the Sierra Nevada in California limit the eastward penetration of mild Pacific air, creating sharp zonal contrasts along their crests. The USDA website has a feature where you can search by ZIP code to find your local plant hardiness zone. 3. 1990 Climatic control of vegetation distribution: The role of the water balance Amer. Heat zones map the number of days per year with a maximum temperature of. (2010), and Vinl et al. <. J. These advances greatly improved the accuracy and detail of the map, especially in mountainous regions of the western United States. The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. Symp. The map is based on the average annual minimum winter temperature, divided into 10-degree Fahrenheit zones. The 19762005 PHZM was produced with the most recent version of parameter-elevation regressions on independent slopes model (PRISM), a well-known climate mapping technology that has generated official USDA 196190 digital climate grids and 19712000 updates (Daly, 2006; Daly et al., 1994, 2002, 2008). CAB International, Wallingford, UK. This feature has been developed in two forms, a freely available single-query tool on the website and a large-scale, batch process tool for commercial applications. 2008 How cold can you go? Here, instead of using elevation as the predictor grid (independent variable in the PRISM local regression function), the CAI method involves using a previously interpolated grid that represents the long-term mean of a related climatological variable as the predictor. USDA Zones 5b through 8b are represented in North Carolina. Amer.

1981 Nature of seed sterility and natural regeneration of Tilia cordata near its northern limit in Finland Ann. The northwest reaches of the region, which include the states of Kentucky and West Virginia, include cold regions in USDA plant hardiness zone 6 (-23.3 to -17.8 C), while the southern reaches of the region, which include the state of Florida, include warm regions in plant hardiness zone 11 (4.4 to 10 C). Nonetheless, the 1990 PHZM mapped much of the Walla Walla Valley in a warmer hardiness zone (7a) than were the Columbia and Yakima Valleys (6b) farther to the west (Fig. Plant cold hardiness: From the laboratory to the field.

USDA Zones 4a through 9a are represented in Washington. 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. 15 45 50, Vogel, K.P., Schmer, M.R. This lack of uniformity in zone intervals prompted the USDA Agricultural Research Service (ARS) to develop its own Plant Hardiness Zone Map with zones defined uniformly by differences in the PH statistic of 5.6 C (10 F) (USDA, 1960, 1965). Clearly, the PH statistic is an important determinant (or a strong correlate of determinants) of the long-term survival and adaptation of perennial plants, but other climatic factors can also be very strong determinants (Skinner, 1962; Thompson et al., 2000). Fortunately, for many parts of the United States, hardiness-zone boundaries have shifted relatively little, as evidenced by the 1960 (USDA, 1960), the 1990 (Cathey, 1990), and the recently updated maps, even though the zone boundaries are a function of the extreme weather events in the various years used to create the maps. Plant hardiness zones identify the location of environmental conditions under which a species or variety of plant can successfully survive and grow. Landscape Plant Development Center, Chanhassen, MN. During the draft map review process, the 30-year period also emerged as the interval that best matched the expectations, perceptions, and experience of TRT reviewers. Although the eastern United States has somewhat similar latitudinal patterns, they are modulated by elevational and coastal influences.

United States Department of Agriculture. & Drapeau, R. 1996 Caractrisation du potentiel de rusticit de sept arbustes ornementaux en fonction de l'intensit des dommages hivernaux Can. Climatologically aided interpolation [CAI (Daly, 2006; Willmott and Robeson, 1995)] was used to interpolate the PHZM. Attempts to understand the highly variable climate of California on plant adaptation may have been the impetus for the broader, multivariate climatic zonation system developed by Sunset in California, first exclusively for the western United States, but expanded in 1997 to the eastern United States (Sunset, 1997) and, in 2001, to southwestern Canada, Alaska, and Hawaii (Brenzel, 2001). This is not a trivial challenge because these weightings will likely vary significantly by region and perhaps also by plant life forms. 6C) conform closely to the boundaries of Kchler's (1964) Black Hills Pine Forest. 1475. J. USDA Zones 5b through 8a are represented in Maryland. Sunset Publ., Menlo Park, CA. The updated PHZM enables users to search for hardiness zones of specific sites by five-digit zip code.

This is mostly a result of using temperature data from a longer and more recent time period; the new map uses data measured at weather stations during the 30-year period 1976-2005. 13. Publ. 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. 1475. The model might locally overestimate survival because the Black Hills have two special climatic characteristics detrimental to woody-plant adaptation, which are unlike the remainder of the north-central United States, where the model was developed (and unlike much of the former nation of Yugoslavia). U.S. Government Printing Office, Washington, DC. You can then choose plants suggested for that USDA zone. Publ. Iowa State University, Ames, IA. opacity: 1;
The map is available as an interactive GIS-based map, for which a broadband Internet connection is recommended, and as static images for those with slower Internet access. However, this relationship is absent in some parts of the western United States, such as central California, where heat zones can vary from 2 [1 to 7 d per year >30 C (86 F)] to 9 [>120 to 150 d per year >30 C (86 F)] within plant hardiness zone 9 [1.1 to 6.7 C (30 to 20 F)] (Fig. As USDA's chief scientific research agency, ARS is leading America towards a better future through agricultural research and information. Take note of these differences as well to help you identify the species. These zones are further divided into 5-degree increments using the letters "a" and "b.". Climate.
