I can hear you right now: “What? Why not? Cheerios is doing a good thing! What’s wrong with their wildflower seeds?” Well, mostly nothing, but it’s the invasive ones that would be better off staying inside the packet:

And many of the flowers on this list are not native to anywhere in the US, so they are not necessarily good matches for our local bees.
