it looks like you are living in the US.
Actinidia arguta are easy to get in the US.
For example from here:https://www.rollingrivernursery.com/products/52/fruiting-vines/hardy-kiwis-actinidia-arguta
I recommend you the 'Ken's Red' variety.
Best taste of all Actinidia arguta I tried so far.
Pamper the fresh planted Kiwis with plenty ( I used 25 cm high) of good organic much and you may also get fruits in 2 years (I was in USDA Zone 7b).
Pittsburgh is in USDA Zone 6a. So, Asimina triloba, Mulberry and Figs ('Round de Bordeaux'; maximum pre-grown in a 60 litre root maker pot) may be your best crops for this zone.
