Between a rock and a hard place....

....literally.  This lily is growing in the narrowest of gaps between the edge of a concrete path and a wooden railing on the south (cold) side of our house.  Each year a plant has emerged and grown, then died offf in the autumn.  This year, to our amazement it has produced three lovely flowers.  I can only assume that it has grown from a seed which has landed in that tiny space a long time ago. There are no lilies like this in our garden. Certainly surviving against the odds.
