Oops, I missed this thread somehow. I'm growing muscadine up my arbor right now. I transplanted the vine from my front yard. It was growing out of a hedge that we tore out. I decided to see if the grape would come back if I transplanted it, so I did my best to dig it up intact (was somewhat successful), then cut the top off and stuck it in the ground by the arbor. It grew a pathetic little vine out of it that first summer (last year), but this year it is back with a vengeance! It grows wild around here, so I just stuck it in the ground and let it be. No care needed. I love it!
You can see it on the right side of the arbor in this photo - the leaves are lobed, which can be seen in some muscadines. They are usually round. Now that the vine is getting bigger, more of the leaves are leafing out round. The plant on the left is jasmine.

We also have a muscadine winery right down the road. Check it out
