This looks just like your beautiful rhododendron logo! And I love that rock wall behind!
That's Tennesee fieldstone. Have it on the front of the house and all around the foundation. I took this picture of the wisteria last week not knowing you would present an opportunity today to post it. Sorry about the quality...I'm not a very good photographer and didn't have the light set right.
Daisy Mae just came into my view right before I snapped the picture. I could never get her to pose like that. :)
