Campanula poscharskyana is a low-growing, evergreen perennial plant, spreading freely by prostrate stems to form a dense mat of growth 8 - 15cm tall, exceptionally to 30cm[
Often grown as an ornamental, where it makes an effective ground cover, the leaves and flowers are edible.
Southeast Europe - Croatia, Montenegro
Naturalized on walls and rocky banks in central and southern England.
|Pollinators||Bees, Flies, Beetles, Lepidoptera, Self
|Cultivation Status||Ornamental, Wild
Campanula poscharskyana is a very cold-hardy species, tolerating winter temperatures falling to at least -20°c[
Prefers a moist but well-drained rich sandy loam and a neutral or alkaline soil in full sun though it also tolerates partial shade[
]. We have seen plants doing very well on a north-west-facing wall[
]. Plants are very drought-tolerant and can be grown on a dry stone wall[
], they also succeed in poor soils[
A rampant spreading plant[
], it makes an excellent ground cover but can become a nuisance if it isn't sited with care[
]. It is generally easily controlled, however, since stems can be easily trimmed to control growth[
The species in this genus do not often hybridize and so seed can generally be relied upon to come true[
]. The plants are self-fertile[
]. This species does not produce seed very freely in Britain, but it is very easily propagated by division[
There are several named forms selected for their ornamental value[
]. The form 'E.K.Toogood' is less invasive[
Members of this genus are rarely if ever troubled by browsing deer[
Leaves - raw or cooked[
]. A pleasant sweet flavour but the leaves are a little tough[
]. It makes a very addition to mixed salads in the winter, though we tend not to eat it much at other times of the year when there are more leaves available[
Flowers - raw. Produced in abundance, they have a pleasant sweet flavour and make a decorative addition to the salad bowl[
A rampantly spreading plant, suitable for ground cover in a sunny position[
Seed - surface sow spring in a cold frame. The seed usually germinates in 2 - 4 weeks at 18°c[
]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Basal cuttings in spring[
]. Harvest the shoots when they are about 10 - 15cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.
Division in spring or autumn[
]. Very easy, the plant can be divided at almost any time of the year[
