- Sow under cover in spring or autumn/winter. Press seed onto the surface of moist compost, may take up to 28 days for seeds to germinate. Once seedlings emerge, pot them on and move to a cooler location before planting out.
An invaluable ground cover, carpeting plant which spreads itself into cracks and joins in patios, terraces, walls and steps.
To stud them with clear blue bell-shaped flowers all summer, and as it is an evergreen, with bright green leaves the rest of the year. Intersperse it with Erigeron karvinskianus which has a similar habit.
The flowers of Campanula portenschlagiana can be eaten raw in salads as well as for adding texture and colour to all maner of cakes, biscuits and puddings.
Deadhead to prolong flowering. Once established plants may be divided during spring or autumn. Dislikes winter wet. May need protection from slugs. Shear plant back if getting leggy.
