Question about Virginia Plants


Carnivorous Plant Addict
Question here. As much as I Love my North Carolina plants is there a difference between NC plants and Virgina Plants from the USA? I know that Virginia seems to get way colder than NC so would plants from Virginia be more winter hardy? I am in Zone 6B. I think Virginia is as well?

Example: S.flava var flava from Virginia USA be more winter hardy than North Carolina S.flava var flava?
