What it's good for, and what it isn't

A low bellflower that forms a tight cushion; from late spring to midsummer its small, ivy-like leaves almost disappear under violet-blue bells. It suits cracks in walls, joints between steps and paving, rock gardens and edging, and grows in sun or part shade as long as the soil drains well; in a hot, dry spot it is happier with midday shade. It spreads more slowly and tidily than the long-trailing Serbian bellflower, but in a good spot it still creeps on by seed and underground runners, so keep it away from small, weak neighbours.

Watch out for

Slugs and snails like it and mainly chew the fresh spring shoots and the flowers. In heavy, waterlogged soil it rots off in winter, and in scorching sun without watering it can burn and die back by late summer. Where it is happy it seeds itself into wall and paving cracks; shearing it after flowering keeps it dense and reduces self-seeding.
