Buckeye tree blossom

Sunday May 7
After our usual morning at church, we got out for a bike ride in the afternoon, on the Little Miami Trail. The tree in my blip is a Buckeye tree, of the genus Aesculus of the soap Berry family, same as the Horse chestnut, which had its origins in the Balkans, but now of course is a very popular tree in England.
The most-notable species is the Ohio buckeye (The plant is the state tree of Ohio, and the term buckeyes is used to refer to Ohioans in general as well as to the sports teams and players of the Ohio State University.
