The&nbsp;Plant Hardiness Zone Map is the guide gardeners use to determine what plants and flowers will most likely thrive in their location. This is the first significant update in more than 20 years. <a href="http://planthardiness.ars.usda.gov">The new online interactive map </a>takes advantage of much more detailed data analysis, and it&rsquo;s making news because it shows that warmer winters are sustaining plants that previously would have died off in colder climates.</p> Thu, 02 Feb 2012 11:00:00 +0000 Rick Ganley 1640 at http://nhpr.org New Planting Map Reflects Warmer Winters
