Plant hardiness is difficult to quantify, since so much of a rose’s success is dependent on local temperature fluctuations, soil types, wind, snow cover, and individual care. In our rose descriptions, hardiness zones are shown in parentheses and refer to the U. S. Department of Agriculture Cold Hardiness Zones, which are based on a region’s average minimum temperature. See the map below for a regional approximation, keeping in mind that individual planting locations can vary depending on exposure.
Most of our roses are hardy to at least Zone 5 (-20° to -10° F), with many hardy in colder Zone 4 (-30° to -20° F) or Zone 3 (-40° to -30° F). We carry a few tender roses for growers in milder climates or for those who want to grow roses in containers. Rose growers in all zones will want to check with local Rose Societies, the American Rose Society, county extension offices, and/or other nearby sources for tips on successful growing in their unique local conditions.
