Could I sow wildflower seeds now for spring?

I have a large bag of mixed wildflower seeds that I never got a chance to plant this year. If I scattered them now, would they start growing in the spring - or at least enough of them to make a difference if I sowed them thick enough (I have far more than I need)? I'm in southern Delaware, zone 7a.
