Need help identifying flower seeds..its a butterfly & hummingbird mix

It could be possible that they mixed the seed with some paper and clay so that the very smallest seeds would get spread evenly. Some of the biggest stuff comes from the most invisible seed. (Foxglove and ageratum, petunia)
Give her a go you have nothing to lose.

Butterfly bush is at the bottom of the first page, I can see how they can get mixed right in to paper/clay and disappear.
