‘Blue Rivulet’ is a selection from many seedlings by Adrian Bloom, chosen for its more compact habit compared to Campanula Blue Waterfall, although its still a vigorous grower. If old flowering stems are cut back to the central crown, then its flowering period extends from May to June (June to October in UK). Prolific star-shaped flowers are lavender-blue, with a whiter center eye.
