Hi Don and welcome to WildflowerHaven Community!
I have embedded a view of your photo from Flickr.com. If this is not acceptable to you then you can delete the image link or let me know so I can.
I am not an expert on wildflowers beyond Texas, but I can usually recognize a lupine when I see one. I believe this is Lupinus diffuses Nutt., Sky-blue Lupine, aka. Oak ridge lupine - http://www.wildflower.org/plants/resu... .
It is found in sandy soils from North Carolina to Florida and along parts of the Gulf states. Very lovely plant and you captured it perfectly.
Thanks for sharing it with us!
