Campanula is a massive genus including more than 300 species of mostly perennials, but also some annuals and biennials. Some are stately, tall garden plants which are excellent choices for borders or cutting. Others are mat-forming or creeping and are perfect for edging or in rock gardens.
It is hard to imagine a rock garden without Bellflowers. Who can resist the quiet charm of the dwarf Campanulas? Rewardingly floriferous, they form a carpet of nodding bells and are hard to beat in terms of floral display. They produce so many flowers that they nearly cover the entire plant. Their flowering stems trail gracefully and look wonderful on the edge of a raised bed or planted in a stone wall where they can weep beautifully.
Easy and accommodating, Campanulas enjoy sunny or partly shaded sites with well-drained soils. If sited properly, they require little if any maintenance.
Below is a list of wonderful species and cultivars for your rock garden. They may also be tucked into steps, walls troughs, for greater interest in the garden.
