Try Solandra, see my post below about which solandra. Evergreen, rampant gower with luxurious foliage and tropical flowers. IN habitat in the Amazon rainforests they have been known to go over 120 feet up trees, so should be no problems to block out your neighbours.

Another option is Kennedia macrophylla, my personal favourite vine at the present time. It comes from the coastal areas south of Perth in Australia, making it fairly cold tolerant, as well as tolernat of dry summers and low fertility. It is in fact a legume so improves the soil fertility as it grows. It has large trifoliate leaves, each one up to 6" long, and quicklyn blocks out any view. It has very atractive orange pea-like flowers with yellow centres, held in fairly large racemes. Basically it looks quite similar to a scarlet runner vine, but is a long live perennial. A picture of one of mine.

Hi banyan, I couldn't readily find the kennedia so I opted for a solandra. Your photo is very nice, it's a pretty vine. I like the big full leaves too. I think it may take a week to get the order then I'll plant it and see how it goes. Thanks very much for your suggestion. I appreciate it a lot.
