Walking home this evening I passed this enormous elderflower tree in full bloom. It smelled so good! I've been wanting to make some home-made elderflower champagne for ages but haven't found any growing near me. I knocked on the door of the house whose garden it was, but there was no answer, no car in the drive- I'm not even sure the house is occupied, it certainly didn't look like anyone was taking care of it. WIBU to pinch some sprigs?
