Can anyone ID this vine?
All right, all you OK gardening folks, can anyone ID this for me? We found it growing rampant in a section of the old chicken barn where the storm last year ripped a section of the roof off. There's a lovely thick layer of manure in there and apparently when you add water and sunlight, this is what happens.
The tri-lobed leaves are easily 5 - 6" wide and the vine is quite vigorous. In all that aged manure, it certainly should be! It's well over 6' tall and is bearing some sort of fruit. The largest of these 'fruits' are about 2" long and 1 to 1 1/2" wide and seem to be slightly tomentose. They are all solid green. I didn't want to mess with it too much until I have an idea of what it might be, or possibly find out if it's toxic. My daughter, who has lived on an OK farm for nearly 20 years, says she has no idea. She's never seen it before, and I certainly never have either.
Can anyone help with the identification? Are we growing a 'crop' here, or is it a new form of the Jolly Green Giant's beanstalk?
