Campanulas are loved for their bell-like, usually blue flowers and long flowering season. Traditionally used in cottage garden schemes, campanulas look particularly lovely when grown under shrub roses. Campanula flowers are extremely attractive to bees and other pollinators.
Campanula poscharskyana is a low-growing, spreading alpine campanula that works well in pots and as ground cover in hot sunny corners. A vigorous plant, spreading by underground runners, Campanula poscharskyana will quickly fill cracks in paving or old walls. Plants bear masses of small, star-shaped, blue flowers from summer to early autumn.
