Four blossoms on our Ohio Buckeye

I was weeding in the back yesterday evening and our Ohio Buckeye (planted 2008 August 30) has four blossoms.  There was a honey bee taking nectar from it's flowers.  This is the first time that our tree has flowered.  I always liked the European horse chestnuts in Toronto with its white flowers.  The Ohio Buckeye is it's North American relative.  Too bad the hail damaged one of its branches.

2012 June 5 - first time this tree has flowered!

Four blossoms this year
