Over the Years - The years have been one with Tall Bellflower. I discovered an interesting little plant in one of my pots a few years back. The basal leaves looked like Violets but not quite. So I wintered it over and waited and waited. Then early July blossoms were forming. Once the flowers opened Tall Bell Flower was simple to identify.
