Pistachio in zone 6-7

[Plantinyum]

Hello, does anyone have experience with growing it in the 6-7 zone mark outdoors ?  I have two two year old seedlings and i'm wanting to plant them in the ground here ...

I would say that it already depends on the variety, some are more resistant to cold than others. But I think that for you it will still be necessary to foresee a small protection.
