This year I've noticed a "sucker" starting to grow from the Wisteria
rootstock.

Normally I would just rub it out, but I am wondering what the rootstock
for this Wisteria is?

Any harm in growing it on enough to see if it will flower eventually?
Keeping it checked so it doesn't take over, of course.

Normally a seedling wisteria is used as a rootstock. But seedling
wisteria can take 20 years to flower which is why they are grafted.

I grew a wisteria from seed once but it died after about ten years
without flowering.
