Regarding plant zones in the USA I have found 5 different websites with 5 different maps, (I’m sure there are many more out there). I currently claim my self to be in zone 8b. Which one is the correct one? http://www.usna.usda.gov/Hardzone/hzm-se1.html http://www.botany.com/zones/hzm-se1.html http://www.eastendcommunity.com/plants/USA_zone_map .htm http://www.arborday.org/media/zones.cfm http://www.floridagardener.com/misc/zones.htm
