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

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 dug up a sucker a couple of years ago and potted it up for fun. It's
growing well (in an 8" long tom). It will be interesting to see how long
it takes to flower, and what it is - maybe bog standard sinensis?

Of course, I have no idea if the umpteen years to flower from seed is
true or not. Is it perhaps one of these gardening "Castaneas" that are
perpetuated without actual experience?
