It's true that no store-bought kiwi will not survive however if you do wish to grow them outside there are a couple of kiwi that'll survive winter in Idaho...A. arguta and A. kolomikta
I recently acquired a pair of red-fruited a. arguta but have yet to find a pair of a. kolomikta; also known as artic beauty because the male has geen, white and pink leaves. And for this reason it is widely sold as an ornamental. The female however is not colorful and so not commonly sold (at least not up here).
"The kiwifruit found in grocery stores (Actinidia deliciosa) is a product of New Zealand that thrives where winter temperatures dip to just 30 and 45 degrees Fahrenheit, which includes USDA Hardiness Zones 7 through 9. Gardeners in northern zones can grow this exotic treat, too—hardy (A. arguta) and super-hardy kiwifruit (A. kolomikta) survive temperatures as low as -25˚F and -40˚F, respectively"
A. arguta & A. kolomikta
