This is a Wisteria that grows up a 20 metre high tree near my barn, it’s taken over 10 years to flower. I got some seed and planted it over 13 years ago, I wouldn’t recommend getting Wisteria from seed, it’s been a long painful wait and only when I threatened to chop it down, did it flower. You have to laugh, the first year I got two flowers on the whole vine! That was two years ago and now it’s magnificent and everyone that sees it wants to know it’s name!!!! I call it the stolen Nooroo (as I sort of pinched the seed) but I believe it is called The Pride of Nooroo! Well at least it looks like it.
