Found: One White Clematis.......

I knew there was a vine growing up from the base of the fence.  I didn't really look at the top of the vine as the bushes on both sides had filled in the area. I started mowing along there and saw one white flower.  After mowing I trimmed back the branches to reveal a mature clematis vine putting out great blooms.  I think the neighbors get to enjoy this one as it does hand down on the other side.  It was a very pleasant surprise to see it doing so well out there in the hot sun.  It got to be watered last evening since it now is totally exposed to the sun and not shaded by branches.
