This happened to me too. I had a really big old wisteria with very scented double flowers. It died and when I found it's trunk was rotten I scraped it a bit and there was a huge larva inside. I thought that had killed it but now I think it was something else and that was a stag horn beetle larva that lives in rotten wood.
Anyway, new shoots started coming out of the ground. They grew quite quickly and within 2 or 3 years they had huge long single flowers, slightly scented. That must have been from the original root stock. I've trained it up the wall and over the balcony rail above and I'm very pleased I did. It's lovely and I dug up another suckering bit and planted it in another place up a post about 4 years ago and it has flowered too.
