The vine with  purple flowers makes its way to our chimney every summer.  By the cold of winter it declines and we pull it back. One year we let our home insurance lapse. The insurance agent came out and told us that we had to trim the bush back so it did not even touch our home.  It was a fire hazard and we could not be insured. In California we do not have that many fires in the fire-place. As long as we do not let the insurance lapse the insurance agent will never know.  The relationship between the red man-made  brick and the lovely nature made  vine well keep their date of  summer merging.
