Ethan,
Have you been reading the posts? I AM in zone 3 and only recently said
that I grow Actinidia kolomitka. I don't know where you got the 200 pounds
of fruit claim. My 3 female plants are growing under ideal conditions with
proper fertilizer, ample water and, together, barely produce 20 lbs.
Actinidia kolomitka, or 'super-hardy kiwi' it is sometimes called, should be
hardy to at least Zone 4, some sources say Zone 3. (Ref = Edible Forest
Gardens vol 2)
So Bill, it should definitely set fruit and ripen in your area.
The hardy kiwis are extremely vigorous - plant them where you've got space.
A single mature hardy kiwi vine can produce up to 200 lbs of fruit per year!
And the fruit is uncommonly delicious.
Cheers,
Ethan
