Dalmatian Bellflower

Rockery plant producing masses of summer flowers

Price 1 Litre Pots £3.99 Each - 3 for £10

A delightful mat forming perennial with a mass of small, rounded, bright green leaves that remain attractive throughout the year. In summer fluted buds open to form upward facing bell-shaped purple-blue flowers; an eye-catching display that lasts for several weeks. This is an easy and versatile plant to grow that will fit into any garden, however small. Ideal for comning with early blooming rock plants such as arabis and aubretia.


Plant in full sun or semi shade at the front of borders, on rockeries, low walls, in gaps in paving or in gravel. Also excellent for pots and containers.


Any well drained soil or good growing medium. Clip off faded flowerheads to promote new growth after flowering. Remove any dead growth in winter. 

The Dalmatian bellflower is extremely hardy and hails from the Dalmatian mountains of Croatia

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
