I've read that Quince C has not been satisfactory in tests at the
Vineland Station here in the Niagara Peninsula; apparently it is less
cold-hardy than Quince A. Provence Quince is reported a little more
cold-hardy than Quince A but is said to grow a slightly bigger tree.
Quince rootstock is somewhat more demanding of soil drainage and soil
moisture than pear rootstock if one wants good production.
For growing unprotected in commercial orchards with sometimes scant
snow, Quince A has been satisfactorily cold-hardy below the Niagara
Escarpment in (old) zone 7a (historic winter low at Vineland minus 16
degrees F.) but not above the escarpment in Agriculture Canada zone 6b.
It's probably a hair more cold-hardy than the classic vinifera grape
cultivars, maybe a hair less than Redhaven peach.
