Northeast Gardening: Help with a weed ID?, 1 by grampapa

I have a rather interesting vining weed. I has lovely little purple flowers right now. Leaves are ferny looking and it has little tendrils to climb with. It mostly grows up the middle of my junipers. Poeple want to know why my junipers bloom. But sometimes it's just tough to get in and pull them out. I found one yesterday that had what looked like little tiny green beans on it. Some had turned black (probably ripe), which is probably why I get them back every year. They are not a huge problem, but I would like to know what they are. I thought I caught some flowers in this picture, but all I have is the vine. gram
