Tussock Bellflower 'White Clips' is a frost-hardy alpine perennial that transforms into a tidy mound of delicate white flowers each late spring. This cultivar of Campanula carpatica grows just 6 to 12 inches tall and spreads 9 to 12 inches wide, making it exceptionally useful for rock gardens, borders, and containers. Hardy in zones 3 through 8, it blooms from May through June with upward-facing, cup-shaped flowers held singly above neat basal foliage. Low maintenance and requiring only moderate water once established, this mountain native thrives in full sun to partial shade and needs minimal fussing to reward you with abundance.

The 'White Clips' form grows as a tight basal mound, offering a remarkably tidy appearance compared to other bellflowers. Its white campanulate flowers appear profusely in late spring and early summer, sometimes reblooming sporadically through fall in cool climates. Unlike its species parent which produces blue flowers, this alba cultivar delivers pure white blooms on a plant that genuinely prefers cool nights and does poorly where summer temperatures consistently exceed 70°F at night. It rarely encounters pest or disease trouble, with only occasional visits from slugs and snails.
Tussock Bellflower thrives as a low-growing groundcover in rock gardens, alpine troughs, and woodland borders. Its compact, spreading habit and long bloom period make it excellent for edging perennial beds or filling the front of mixed plantings. Many gardeners grow it in containers where its neat mound and abundant flowers can be appreciated up close, and it performs well in these contained spaces thanks to its shallow root system and moderate moisture needs.
No timeline data available yet for this variety.
Start seeds indoors at 60 to 70°F. Cold stratification is recommended for best germination; refer to seed packet instructions for your specific timeline. Transplant seedlings outdoors after the last frost date once they have developed true leaves and the soil has warmed.
Transplant hardened-off seedlings outdoors after the last spring frost. Space plants 12 inches apart in rows 24 inches apart, or adjust spacing based on your garden design. Ensure soil is well-draining and moderately moist at planting time.
Direct sowing is possible but seed starting indoors is recommended since most plants won't produce blooms until the second year.
Cut plants back to basal growth if foliage deteriorates during summer heat or after extended bloom. Deadheading spent flowers, though labor-intensive, encourages additional blooms and extends the flowering season into late summer and early fall, particularly in cool climates. Divide clumps every two years to rejuvenate the plant and maintain its compact, tidy appearance.
