Edible Evergreens for zone 7

Any edible plant parts are fine unless harvesting the plant destroys it, like tubers.

I've compiled a list of plants I have so far, but I have yet to find a vine I'm really thrilled about:
Groundcovers: Viola Odorata, Vaccinium Vitis-Idae, Gaultheria Procumbens, Fragaria Vesca, Chamaemelum Nobile, Thymus Sp.
Shrubs: Osmanthus Fragrans, Camellia Sinensis, Gaultheria Shallon, Vaccinium Ovatum, Elaeagnus Ebbingei.
Trees: Ilex Vomitoria, Camellia Oleifera

For vines, I've considered Rosa Banksiae: though I've read all roses are edible, I haven't found any notes on whether or not this species is suitable for eating, nor am I certain it would be evergreen in my zone 7 winters. Akebia Quinata: the fruit has gotten very mixed reviews, and again I'm not certain it would be fully evergreen. Lonicera Japonica would be lovely if it weren't so invasive. Maybe there's a sterile cultivar?

Daylilies and hostas... don't know if hostas are evergreen there?

Scarlet Runner Bean is an annual climber. Yum. And pretty flowers.

Oh sorry you said evergreen.
I think all rose hips are edible, but the "Lady Banks Rose" you are thinking about can get about as large as your house!
Hmm. What else might you do...
Well, maybe you could instead espalier an edible shrub, like Camellia sinensis, and make your own tea. Or espalier some blueberries along the fence or house or wherever you want the climber?
Or give up on evergreen, Better list of choices if deciduous.

I have about 60' of fence with an arch over the path in the middle. I was hoping for a vine as it will likely cover the length in green much faster and cheaper than alternative shrubs and trees.

I can't come up with any new ideas for edible evergreen vines for zone 7, except for the Akebia you mentioned. I googled to see if anyone had come up with a more tasty cultivar, but did not find one. Here is a link the Raintree Nursery, a place near here, with a wonderful reputation, that specializes in edibles. You might call and ask if any of their 4 Akebia cultivars is better tasting than the other. Also, if you choose Akebia, they say you need two varieties for pollination and fruit. Maybe you could do like farm wives have done for millennia with less-than-tasty crops like rhubarb and cranberries etc- mix it with something yummier, or add sugar!.

Or how about plant the shrubs along the fence from the tiniest and cheapest pots, but plan to have edible annuals on the fence for several years, those are as cheap as a packet of seeds!
