Boggle. None of the quince trees I have ever seen would grow well
as a hedge, or be suitable for canes. Japonica would.

Anyway, true quinces are NOT high-acid when ripe, which can be seen
by the fact that jelly made from them needs lemon juice to set well
(or japonica).

None of the ones I've used have needed any help to set.

They are somewhat mouth-wrinkling, but that is not
due to acid.

Indeed.
