Bells and Whistles Clustered Bellflower (Campanula glomerata ‘Bells and Whistles’) creates a dazzling display of deep violet-blue blooms from late spring to early summer. Its upright habit, rising to 24–28 inches tall with a spread of 22–26 inches, offers a commanding presence among garden perennials. Each clustered flower adds remarkable color set against mounds of green foliage, making this bellflower an ideal choice for eye-catching borders or statement plantings. Unlike many other varieties, it continues to shine all season and resists deer, giving you peace of mind.

In addition to its bold flowers, Bells and Whistles draws butterflies and hummingbirds with its abundant nectar. Though not highly fragrant, it proves adaptable to various soils and thrives in full sun or part shade—especially beneficial in warmer climates where a touch of shade helps prolong bloom color. Its medium growth rate suits different design styles, whether planted en masse for sweeping color or tucked into containers for an elegant accent. Native to parts of Europe and Asia, this clustered bellflower has found a place in diverse landscapes thanks to its easygoing nature and showy floral clusters.

Bells and Whistles Clustered Bellflower Care

Plant in well-draining, moderately fertile soil, keeping the pH anywhere from slightly acidic to alkaline. Maintain average moisture and situate in full sun or part shade, providing some afternoon shade in areas with hot summers. A balanced, slow-release fertilizer in spring can help encourage vigorous blooms. Regular watering is beneficial during active growth, but avoid waterlogged conditions to deter root issues.

Pruning involves cutting back stems after the main flowering flush to encourage compact growth and possibly a second round of blooms. Thinning out older or damaged stems can also boost airflow and deter pests. In colder regions, mulch lightly around the base for winter protection, particularly if grown in containers. Containers benefit from more frequent watering and occasional light trimming to keep growth neat.

Bells and Whistles Clustered Bellflower Spacing

Place individual plants 22 to 26 inches apart for mass plantings or rows, allowing them ample room to create a dramatic, unified display. When grown in containers, consider using a pot at least 12 inches in diameter to accommodate the root system and promote healthy growth.
