I used the wild seed mix that I purchased from joblots, a local store in my area. I did this each year but have yet to see any yield from it. The best thing to do is purchase seeds from a great store online such as Johnny's selected seeds or plants that are growing from a nursery. It's tricky I know.

Ldylahla, are you talking about the boxes and cans of wild flower seeds from JobLot?( I am in SE MA)
That too bad you did not have any luck with them. I had great luck.
