So this vine climbs my fences, Rose of Sharon, grape vines, tomatoes, black raspberries and everything else that it can get its stem on.
I don't think it is Honeyvine( Cynanchum laeve) or Milkweed Vine(Morrenia odorata), be cause the leaves are alternating , not paired.
The sap is not milky, and even though I thought it had "milkweed" type pods, I now think that the pods are marble sized with buckwheat like seeds and the "milkweed pods" are from a relatively minor population of Honeyvine.
I will try to attach some pictures, but if I am unable to, does my description match bindweed?
The shape and veining on the leaves don't look like bindweed to me, but it's so variable and I know nothing of eastern plant variations.
Look at p 42, Dioscorea oppositifolia or cinnamon vine in this PDF, see what you think.
