What's this Flower?

I deadhead flowers and collect the seeds from various plants when I'm out looking at gardens around the area, then throw them out in the garden. This may be one from one of my excursions or may have been brought in by the birds. It grew last year and is bigger this year than last so it may be a perennial but because I live in a temperate climate, some annuals grow like perennials.

The leaves look "maple like" but with three major sections. The flowers stand up from the leaves. Because there is other foliage around them, it might be hard to tell but hopefully someone can identify this for me.
