Campanula carpatica is one of the most popular and easily grown alpine campanula species, having very large wide open flowers. Most varieties have white or blue flowers, borne from early to late summer. Campanula carpatica f. alba ‘White Clips’ is a lovely white-flowered campanula. It’s easy to grow, forming low-growing mounds of foliage with upward-facing white bell-shaped flowers for weeks on end. It’s useful for growing in rockeries and alpine troughs and is robust enough to plant at the front of a border where it will bring pockets of freshness to summer displays. For best results grow Campanula carpatica f. alba ‘White Clips’ in moist but well-drained soil in full sun to partial shade. Deadhead spent blooms to prolong flowering.
