Most cold-hardy Feijoa variety?

Hey all, living in zone 7(b) [north Alabama]

I’m hoping to plant Feijoa here, but I’m completely ignorant of which varieties would grow best in our winters (this year I think it got down to 15 degrees here very briefly, but it has been known to get colder, down to maybe 5).

Anyone know what varieties would work best here?

I live in North Carolina, and am on the 7b/8a line, and it looks like we may have almost the exact same hardiness zone.

I'm growing a few different varieties, and all are doing well so far even through this colder and wetter winter we've had this year. I bet you probably wouldn't have a problem with any of the varieties either as far as cold hardiness goes. I haven't had any fruit yet, so I'm not sure about that, but choosing an earlier ripening variety may be best to ensure it ripens for you.

Hope this helps a little! Maybe some others will have some additional info, that have harvested fruit or are growing them in colder locations.
