Hi and thanks for contacting Ask an Expert.
This looks like a hardy kiwi, with the twisted, woody stems and the leaf configuration. Did it bloom this spring? Hardy kiwis taste the same and the fuzzy ones but you can eat the whole fruit, skin and all. And they are about the size of a large walnut maybe a bit larger.
Kiwis need at least one male plant and one female for fruit to develop on the female. You can have up to 8 females to one male plant, if you want kiwis. They produce a tremendous amount of fruit.
You can look at male and female blossoms to find out which you have. I attached a link on discerning male or female blossoms. The vines can become quite large and heavy and weigh down the fence behind the pictured plant. If you want fruit, you will need to wait until next spring to figure out if you have a male or female (by the blossom) and then add the appropriate plant to the yard. I am attaching a ‘book’ on kiwis if you are interested in further information on them.
If all you want is a nice landscape plant, just keep it pruned.http://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/20677/pnw507.pdf https://www.gardeningknowhow.com/edible/fruits/kiwi/sex-of-kiwi-plants.htm
