supplies Ottawa 3 and Vineland 3 rootstocks.

Vineland 3 is reported to be prairie hardy and somewhat more dwarfing 
than Ottawa 3. These may be small plants from tissue culture, check.

If you have rabbit or deer issues and can't fence, dwarfing stocks may 
not be for you.

A couple of decades ago Columbia crab seedlings were preferred to 
Siberian crab seedlings on the Prairies as being more reliably 
compatible with scions. Columbia crab resulted from a cross between 
Broad Green, an old Russian apple, and Siberian crab.

More recently Ranetka crab (I think a Dolgo/Siberian cross) has found 
favour. If you do a search on "Malus ranetka" you will come up with a 
post to this list from 2000 which diacusses Malus ranetka.
