A more resilient plant that is &#8220;hardy to zone 9&#8221; can tolerate a minimum temperature of -7\u00b0C. First developed for the United States by the Department of Agriculture (USDA), the use of the zones has been adopted by other nations.<\/p>\n<p>Whew &#8211; now if you aren&#8217;t totally confused by that, we suggest you use Hardiness Zone Maps as a general guide for selecting suitable plants for your region.\u00a0 Use the map links below (the USDA Interactive Map is way cool) or look at the above map to locate your area and plant hardiness zone.\u00a0 Then when you visit your local garden centre, check the Heritage tag for that particular plant&#8217;s hardiness zone.\u00a0 If you are in doubt be sure to ask the staff to help you out.\u00a0 Keep in mind though that many other factors affect overwintering of perennials.\u00a0 Some of these factors include:\u00a0 reliability and depth of snow cover,\u00a0 soil moisture levels and site-specific micro-climates.\u00a0 Some experienced gardeners like to &#8220;push&#8221; zones but newbies should perhaps select plants within their zone in order to be more successful in their first attempts at gardening.<\/p>\n<p>To find your hardiness zone in the US, we&#8217;ve provided a link to the <strong>USDA Interactive<\/strong> Plant Hardiness Map, just <a title=\"New USDA Interactive Plant Hardiness Map\" href=\"http:\/\/planthardiness.ars.usda.gov\/PHZMWeb\/InteractiveMap.aspx\">click here<\/a> &#8230;\u00a0\u00a0 you will be asked to validate a code for security purposes<\/p>\n<p>Most Canadian nurseries use the USDA zoning for Canada, not the Canada Hardiness Zone Map, but for your interest and an <a title=\"Natural Resources comparison on US vs Canadian Zones\" href=\"http:\/\/planthardiness.gc.ca\/index.pl?m=17&amp;lang=en\" target=\"_blank\" rel=\"noopener noreferrer\">excellent article comparing the two<\/a>, visit the Natural Resources Canada Plant Hardiness Map, just <a title=\"Natural Resources Canada Plant Hardiness Zone Map\" href=\"http:\/\/planthardiness.gc.ca\/?lang=en&amp;m=24&amp;speciesid=1000000&amp;phz=usda1961-1990&amp;bc=1\" target=\"_blank\" rel=\"noopener noreferrer\">click here for the link <\/a>&#8230;<\/p>\n<p>You can also take a look at our simplified Hardiness Table here on this site under Perennials 101, Selecting and Planting Perennials.<\/p>\n\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>According to Wikipedia, hardiness zone is a geographically defined area in which a specific category of plant life is capable of growing, as defined by climatic conditions, including its ability to withstand the minimum temperatures of the zone.\u00a0 For example, a plant that is described as &#8220;hardy to zone 10&#8221; means that the plant can [&hellip;]<\/p>\n","protected":false},"author":5,"featured_media":3667,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[86,108],"tags":[],"class_list":["post-3665","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-gardeners-resources","category-plant-hardiness-zone-maps"],"_links":{"self":[{"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/posts\/3665","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/comments?post=3665"}],"version-history":[{"count":5,"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/posts\/3665\/revisions"}],"predecessor-version":[{"id":4224,"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/posts\/3665\/revisions\/4224"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/media\/3667"}],"wp:attachment":[{"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/media?parent=3665"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/categories?post=3665"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.perennials.com\/content\/wp-json\/wp\/v2\/tags?post=3665"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
