These differences are minor compared to the major difference in size and
vigour, W. floribunda is a much smaller plant at a mere 40' W. sinensis can
get to 120' and bring down house fronts with the shear weight of it (I will
admit not many posters are likely to live long enough to have that problem!)
most named forms are from sinensis and almost all wisteria is grafted onto
sinensis roots anyway so you get a pretty vigorous plant what ever. I still
prefer to do my Wisteria floribunda from cuttings, it seems a much more
modest sized plant! (covered in buds at present)

We certainly wouldn't plant a W. sinensis against the house again. It got
up into gutters, under roof tiles and lifted some of the tiles the side of
the house is clad with. It was a poor 'doer' anyway, so we were glad to see
the back of it. We've got one as a standard on the big lawn and want to put
in two more and I'd like at least one to be a W. floribunda. One doesn't
often see Wisteria grown as a standard but it's a lovely sight and while we
just bunged ours in, this site gives more info on how to do it:
