I'm not sure how far north the best of the trifoliate crosses will go,  
but I have plenty of seeds of a citrus called Roundleaf (Sanford  
citrange x changsha mandarin) originally called sancichang # 10 by Dr  
Brown who made the cross.

I would guess it could be hardy to zero degrees F--perhaps more  
perhaps less.  It is sour and if you stay away from the skin which has  
some trifoliate gum cells, has a juice that is basically sour and  
edible enough.  I use it here where tasty things grow as a decoy plant  
to keep sidewalk visitors from hopping the fence and don't eat it.   
The fruit looks a bit like a Seville orange.  That is somewhat like an  
orange. I have neighbors who come back and pick it every year, so it  
is certainly decent enough.
