Did you know you can grow kiwis right in your own back yard? Not the grocery store kind. But the fruit of 'Hardy Red' kiwi vine is a cousin. The berries have the same sweet-and-sour taste, maybe a little sweeter. And they're smooth skinned so you can eat them like grapes. 

'Hardy Red' kiwi vine is female, and that's important if you want to grow it for the fruit as
well as the flowers,
because you'll need a male vine for pollination. 'Hardy Red'
is hardy to -25, so you can be confident Chicago winters
won't faze it.  And it's happy in full sun or
part shade. However, it will need frequent pruning and strong
support...the vines are large and heavy and bear about 100 pounds of
berries a year.  A note of warning to cat owners: this vine smells like
catnip to cats, and they may harm foliage or dig at the roots.
