Fast Growing Heirloom food Vine

Hi, crazy idea.  Have a lawn swing where the canvas top has torn.  The top isn't easy to replace, they want you to buy a whole new swing.  I've seen beans and peas overgrow fences and would like to plant something like this to replace the canopy.  I would also like to get into heirloom varieties.  If you have seeds or can advise on varieties please let me know.

HI
Maybe a little late now but scarlet runner beans will grow fast and they have a lovely red flower. THe beans should be harvested before they get too big and you need to destring them.  I like them best if they are frenched (cut lengthwise into thin strips) They are very vigorous.
Or have you considered grapes?

If it were me, I would use Hardy Kiwi.  See Burnt Ridge nursery to order.

Anything you plant right on the frame will likely droop and get in the way of enjoyment of the swing, so I recommend putting a frame higher up and growing grapes on that. The green leaves will shade you in the summer and fall off in winter so you can still enjoy sitting out on a warm winter/spring day.
