Answer: Wisteria is one of the most spectacular vines you can grow - it is also one of the more challenging. Perhaps I should modify that...the vine is easy to grow, the challenge is getting it to flower. I think the youngest wisteria I have heard of producingflowers is 3 years old. I have a family member who has a 10 year old wisteria with no blooms (we have tried just about everything!) A few tips on growing: Wisteria floribunda (Japanese Wisteria) likes full sun unless you are in a very warm climate, in that case they will accept partial shade. You may have a problem in the area you propose with lighting. Another more important point...be very, very careful when growing wisteria in places where it can reach your roof. Wisteria vines can disrupt clapboards and shingles. They also should not be grown in trees because the vine can harm the tree. I didn't mean to be anti-wisteria, I just want you to know the facts before you make a decision. If you decide against the wisteria but still want a flowering vine for your spot, submit another question via the website and we'll give you some suggestions.
