Who knows what plant this really is - it has strange purple flowers, makes balls full of seeds & grows in vine

Could be a passion flower, or in the south, a common weed, called May-Pop. It is a Vine.

Sounds like a clematis to me.
Reply:I think what you are describing is a Clematis. They are a beautiful vining flower. I hope this helps.
Reply:Is it perchance, an Angel's Trumpet? I have grown Angel's Trumpet's in my Garden and they are a muted purple. The flowers are only in bloom for about a day, but they are big. Much bigger than a standard flower, almost like a huge petunia. After they have bloomed they produce a spiny pod that contains seeds.

Or there is a plant that produces purple flowers that look like loose pompoms and they are called Monarda. They are a wild flower and related to Bergamot. They produce pods but only on top of where the flower is.

There is also the Shoo Fly Plant, it too produces purple flowers with white in the middle. It is a hearty self seeder and considered a weed.

Then there is the clematis, it is a climbing plant, a vine. It produces pods of seeds.
