Campanula ‘Crystal’ is a robust perennial known for its large, palest icy amethyst pixie-hat bells that bloom from June to August. Reaching a height of 75cm, it is considered the strong-growing equivalent of Campanula x burghaltii, with a more vigorous growth habit and abundant flowering. This variety thrives in well-drained soil and full sun to partial shade, making it a versatile choice for borders, containers, or as a focal point in a mixed planting scheme. Its unique flower shape and colour add a whimsical charm to the garden, while its resilience and ease of care make it a favourite among gardeners looking for dependable, long-blooming plants.
