Ok over winter when I can't see my plants I have decided I want to build another Bog garden. However I keep having visions of Darlingtonia growing along a stream. I live in Ohio as everyone knows and our climate is vastly different from Oregon. The record low of Florence Oregon is 9* F while here in New Carlisle the record low is -25* F. That's a difference of 34*F. Now I am basing this off of record lows simply because those are the worst of the worst and as my dad always said plan for the worst. Now it is my understanding that plants have to be able to be extremely adaptable. It would be advantageous for a zone 7/8 plant to survive in zone 5/6 and we have all heard stories of it happening such as D. Capensis and Highland Neps surviving freezes. So here is my question what do you think the lowest temperature a carnivorous plant can survive for a long time. Would it be possible for a Darlingtonia to survive a month with -5* F out in the wild? I mean I understand it is supposed suicide for a plant like this to endure these temperatures for extended times unmulched but to use the famous quote "Plants don't read books". I mean just because a Cobra hasn't endured extremely low temps for long times doesn't mean it isn't capable of. What about genetic variability. If I got a large group of genetically diverse plants and let them endure an Ohio winter and by chance some survived to breeding age would the offspring of these cold tempered plants be cold hardy? What if someone were to set up a control population of plants and let them go for like 10-15 years? Would the plants have genetically adapted to the Ohio environment to be considered a different cultivar/subspecies since they are now surviving in aplce regular Darlingtonia's don't? Now for this example I am using Dar's because that is what's important to my situation but I think it would be useful to know the extreme's that any plant can survive, even if it means extensive testing is needed. Am I being clear enough?
