Ann, do you mean a blue circle or something else? I'm not sure a globe that small would be distinguishable as to what it is, but I don't know.
Here is one image that could go behind a circle (maybe). It's public domain (USDA). Would something like that go inside the blue? Or behind the globe? Of course, wildflowers are natives, but not all natives are wildflowers. That's why this is tricky, methinks.
And if I can ever find where I put the image, I'll post it.
Maybe stylized compass points to represent all corners of the globe with something superimposed on that? Just throwing out ideas. But, iMHO, we can get too far afield (no pun intended) from the category Natives and Wildflowers. Simple and stylized.
