This exact question was asked on the Bulb list, by a guy in
California (who wanted to know if Tazetta Narcissus would survive in
the Netherlands since part of that country is listed as being in USDA
Zone 8, and Tazettas are considered hardy in Zone 8.) There was much
discussion about the differences that can exist in different
locations in the world even though they are the same USDA Zone. For
more information see the following:
