A Note
on Hardiness
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.
