Campanula glomerata / Clustered Bellflower / British Wildflower /Seeds

A British wildflower and good garden plant. Clustered Bell Flowers have compact heads of deep violet-blue flowers on upright stems from June to September. Plants grow to a height of about 30cm and look great in borders and gravel gardens and wilder open parts of your garden.  Plants grow in the wild in grasslands and woodland edges.  They attract lots of pollinators into the garden

Clustered Bell Flowers grow best in full to part sun and neutral to alkaline well-drained soil.  These plants are very cold hardy.

Pack of approx 1000 seeds.  Sow in spring to autumn.  Germination is erratic, so sow more than you need.  Flowering generally starts in the second year, but may start in the first year from early spring sowings.  Sowing instructions and a colour photo are printed on the packet.

Hardiness Hardy herbaceous perennial (RHS Hardiness H7)
Flowers June to September
Height 30cm
Spread 20-30cm
Conditions  Grow in full sun to part shade and fertile well-drained soil.

Sow in spring to autumn on the surface of a shallow tray of seed compost.   Do not exclude light which helps germination.  Keep at 15-20C and seeds germinate in 1-4 weeks, sometimes longer. If there is no germination move the seed tray into a fridge for 2-4 weeks and back into the warmth and this may help to break seed dormancy.  Transplant seedlings to pots when they are big enough to handle and into the garden after the last frost.  Early spring sowings may flower in the first year.   Seeds can be direct sown into open cultivated soil in autumn for germination in the spring.


Protect young seedlings and shoots from slugs and snails.  Cut back after flowering to keep a good shape, and there may be a second flush of flowers.  Basal cuttings can be taken in spring.
