These last withered Concord grapes (
Vitis labrusca) hang in the corner of the small yard fence.
Concord grapes are a cultivated variety of the native New England fox grape, developed in Concord Massachusetts. They are one of a small handful of conspicuous sweet fruits edible to humans native to our area. Birds and other animals like them very much, and between the blue jays and the gray squirrels, the humans at the house got to eat very few grapes. Wine grapes that are hybridized with or grafted onto fox grapes are resistant to disease and cold.
Apparently the first owners of our house planted many fruit trees and shrubs; we suspect that these grape vines--thick as a baseball bat at the base--are the last remaining fruit plants in the yard from that time.
Wikipedia claims that the name "fox grape" and the "foxy" taste of these grapes has nothing to do with the animal the fox.
I tend to disagree. (Whether or not I'm full of it, I think that's one of my better essays. I think you should read it.)

Grapes climb by way of spiraling tendrils. (As opposed to
Boston ivy which uses adhesive disks, or
poison ivy which uses hair-like aerial roots, or
Oriental bittersweet which twines secondary stems around a structure.)
