Ok, I have read more and more frequently "that dormant or evergreen" is not a reliable trait for hardiness. That even dormant or evergreen behavior is very questionable in different gardens. Evergreen plants here in Alabama would most certainly not appear that way in Minnesota. They would most likely behave as dormants, so...my question is should dormant or evergreen even be considered in a program for hardiness, or should it focus strictly on plants that are actually hardy regardless of their foliage behavior in winter. So if plants are breed to be more hardy in cold zones, will they end up being more prone to heat dormancy in hot zones?
