WALL BELLFLOWER Campanula poscharskyana
A tough rockery plant bears massive sprays of violet starry flowers. Vigorous and fast growing, it is one of the easiest and long-flowering of all rockery plants, and able to stand almost complete drying out once established in a wall. Unlike many others it will self-seed into cracks making a fantastic display!
