Question
I live in East Central Alabama and just came across a wild vine I have never seen.  It has heart-shaped leaves that are similar in texture to a grapevine and is now (October)producing berries that range in color from light turquoise to an almost cobalt blue that grow in clusters on the vine and are about the size of holly or nandina berries. Also if you figure out what it is, could you please advise re: toxicity and method of propagation, as it is a beautiful vine that I would love to try to grow in my yard.

Answer
Not really sure without a picture, but it sounds like a porcelain vine.  Check out the image search below to see if I'm right.  The plant is very invasive in Florida and moderately so here in Alabama.  I don't know if it is toxic.
