Large evergreen climber for pergola

Hi everybody,
I have replaced my rotten old decking area with new and built a pergola over it. I'm dying to finish it but I've had a catastrophic cycle crash in which I broke my left collar bone, right wrist and a couple of ribs.
Anyway what I'm currently trying to decide on is the best evergreen climber to grow over it. I was a bit worried by some research I did that showed some climbers do not grow beyond 3 meters, not quite enough to reach the top of the pergola from the front which is just over 3 meters (2.4 meters from the back). The pergola will get full sun all day for almost all of the year but will obviously be open to cold winds (apparently this is a problem for some). I live in East Hampshire, the soil is quite good, a little sandy and drains well. I would be prepared to plant a climber in each corner if necessary to get the required cover. Not really bothered either way about flowers, my wife suffers from hay fever anyway, I do like attractive leaves though and it would be great if it grew quite quickly so I don't have to wait years for the pergola to be covered. I've included a photo of said pergola to make things clearer, the area is about 5x5 meters.
Thanks for any ideas you can offer.

 

plant a grape vine

 

I've planted an honeysuckle in my garden and its growing like a good un and smells beautiful

 

I was led to believe that grapevine was deciduous?

 

Akebia certainly grows big enough. It's got pretty leaves, attractive (and slightly unusual) flowers, and there isn't enough of it around for you to be sensitised to it hayfever-wise.

 

Thanks for all your suggestions. I rather like the sound of Akebia as it's more resistant to cold winds which it will get plenty of. Hopefully I'll get the project completed this year and I'll put up some pics of the finished article.

 

it is, but who sits in the pergoda over winter

 

I don't get the idea of an ever green climber.
To me it's nice to get some sunshine in the winter, ever greens can be a bit too much in winter.

 

True, but it fills the view up the garden from the house so I want it to look green all the time.

having second thoughts about the Akebia as I have learned that it’s an invasive species. Going to try Clematis Armandii and hope it copes with the weather.

 

Hello again, so I went online and bought myself a Clematis Armandii which my wife has kindly planted because I'm still a bit broken. I'm not too sure about the condition of it though. As you can see from the images several of the leaves are dead and the top had been cut off (pruned). Is this going to be ok? As you can tell I know very little about plants at this stage.

 

Thanks for all that brilliant information, I feel like I've made the right choice. I was just a bit worried about the state it turned up in, I guess plants are going to suffer a bit durning delivery.
