Does your seed packet say 'Southeastern Mix'? Or 'General Mix', maybe? Look at the bottom of the page linked below to see what might be included.
I noticed that of the 6 primary flowers included in the SE Mix, none are actually native to the SE (Coreopsis tinctoria used to grow mostly in the Central Plains, but is now in almost all US states, so that's as close as it gets).
There are some other natives and non-natives listed as being less well represented in the mix. I might plant them just to see what comes up, but be aware that Dame's Rocket, for instance, is considered invasive in some (many?) states.
