The “mystery” is that I have no idea what kind of flower this is! Here on campus are both lavender and reddish pink. Taking a close-up, I was intrigued by their unusual centers.

I think it’s wild bergamot, also known as bee balm! : ) These flowers fill the garden prairie of our arboretum.
Thanks, Rebecca – I looked wild bergamot up and I think that is what it must be, even though the center of the flower seems to be different.
Yes, I noticed that too. Mysterious… 🙂
