Overview
Campanula alpina, the alpine bellflower, is a charming miniature that perfectly adorns rock gardens and shady corners. This hardy alpine originates from the Alps and Carpathians, creating year-round attractive groundcover with its compact growth habit.
Appearance and Bloom
The alpine bellflower is a true miniaturist. The plant reaches only 15-20 cm in height and forms dense cushions of narrow, dark green foliage. In spring and early summer, numerous small blue-purple bell-shaped flowers appear, lasting until August. Blooms grow from slender stems, giving the plant an elegant, delicate appearance.
Ideal Location
Campanula alpina thrives in semi-shade to full shade. A spot beneath trees or against a north-facing wall is ideal. It also accepts full sun if soil remains adequately moist. Plant this alpine on rocks, in walls, or in raised beds where drainage is assured.
Soil
The alpine bellflower requires well-draining soil. A mixture of garden soil with gravel or perlite works well. pH should be neutral to slightly acidic (pH 6.0-7.0). Ensure good drainage especially in winter to prevent root rot.
Watering
Water regularly during the growing season, especially in dry weather. Ensure soil never dries completely but avoids waterlogging. Water less in winter. Mulching around the plant helps retain moisture.

Pruning
Minimal pruning needed. Remove spent flowers after blooming to encourage regrowth. In spring, trim yellowed or dead foliage. For bushy form, lightly cut back after flowering.
Maintenance Calendar
February: Prepare soil and plant. March: First feeding with slow-release fertilizer. May-August: Regular watering and deadheading. October: Disease inspection. November-December: Minimal care, add mulch.
Winter Hardiness
Campanula alpina is completely winter hardy to -25 C and tolerates snow and frost without issues. In very wet winters, drainage becomes essential. Perfect for Northern European gardens.
Companion Plants
Pair alpine bellflower with other alpine plants like sedum, saxifraga, or alpine phlox. In shade, it looks lovely with Helleborus or Epimedium. On rock gardens, it pairs beautifully with low-growing thyme.
Closing
Campanula alpina is a precious addition for those with space for a rock garden or raised bed. With its tiny size, winter hardiness, and long blooming period, this alpine offers years of beauty. Find this plant at specialty nurseries and on gardenworld.app/en for design inspiration.
