I don't know why hardy begonia is so rare, because propagating it is simple.
You can root cuttings, divide the tuberous roots, or grow it from seed.

Seed or bulbils? Mine produce several bulbils in every axil they
detach easily and every one produces at least one new plant :-))

I scatter them in likely places & they bloom the second or third year
