It's just a marketing ploy for the vendor selling it as a 9a tree to sell more. There's zero Federal laws that would stop a vendor from labelling a citrus tree to grow in zone 5 even though it would have zero chance of surviving the winter in a zone 5 area in Minnesota for example.
Also the climate zones continuously change, plus the maps are just a rough approximation of each zone, and not to mention the effect of microclimates that actually make a significant difference in some cases.

What I understand, is there was widespread dying of foxtails, arecas and christmas palms last year... from a very AVERAGE winter, and people should know the truth.
