Well, I'm new to gardening, but here's my two cents:

I did some research on climbing vines because I wanted to see something pretty covering my fence, but didn't want the destructiveness of say, english ivy. After much consideration, I decided upon Morning Glory and Moonflower. Both entwine rather than damage, but both reseed agressively. If you aren't worried about reseeding, then I would try those. They really are beautiful, but you would have to keep them in check. Also, Sweet Pea might be a good candidate, but I think they are vigorous reseeders as well.

I looked at Nicotania (sp) as well. I think they are perennial though. Might take some time to establish. Not positive on this, however, because I stopped looking after the MG's and Moonflower.

Im sure the experts here would have more info for you, but I figured I should share what I have learned to sort of...give back, as it were.

Steff :)

you're going to want something that can withstand a lot of snow, as i'm sure you're learning. hmmm. what about trumpet vine? i hear that takes off like mad and is impossible to kill but i don't think wv has banned it. or honeysuckle? are you wanting an annual or perennial?

check on the seed exchange and plant exchange forum before you buy seeds-- you might be able to find multiple things, or get cuttings, which would be faster, for trades or sometimes sasbe.

in my experience, moonvine is slow to flower.

I've grown a variety of annual vines. Moonflower vine grows the biggest and strongest for me. It doesn't flower for me until late summer. But it can get big, almost forming a trunk.
I haven't experienced reseeding in Zone 6.
I also like hyacinth bean vine, and scarlet runner beans.

Thank you all for replying.

Steff: and a very bright and shiny two cents they are. I have grown Moonflowers and several varieties of Morning glories and loved them, and that is probably what I will go with, but I wanted to ask here about some of the other options. Mainly, I want something vigorous enough to climb to the top of the hideous thing. I am growing Sweet peas this year, but I wasn't sure if they would be tall enough.
rosemctier: I just came in from playing in the snow. I am looking for an annual, for several reasons, so I am not worried about its cold hardiness, just if I can get it established before I leave for the summer. Thanks for the seed tip.
weebay: I like scarlet runner beans, but would they get tall enough?

A couple of things to consider

-sweet peas like cool weather. If you're growing this for summer, consider what your weather might be like

- some viney plants need help to climb. They require a little human intervention to feed them up a trellis or strings. If you're leaving for the summer, you want something with good tendrils that will do the climbing itself.

I've had Scarlet Runner Beans climb twine from a trellis to the 2nd floor window! The neighbors called it the magic beanstalk!
