Campanula lasiocarpa is a herbaceous, perennial plant producing a cluster of unbranched stems 3 - 18cm tall from a creeping, rhizomatous rootstock. Each stem bears a single flower, the plant spreading to form a carpet of growth[
The plant is sometimes harvested from the wild for local use as a food. It is grown as an ornamental in gardens.
E. Asia - Russian Far East, Japan; Western N. America - Alaska, Northwest Territories, Yukon, British Colombia, Alberta, Washington
Gravelly and sandy slopes[
]. Crevices in rocks and on rocky slopes in alpine areas; at elevations from 1,600 - 3,100 metres on Honshu, 1,000 - 2,000 metres on Hokkaido[
|Pollinators||Bees, Flies, Beetles, Lepidoptera, Self
|Cultivation Status||Ornamental, Wild
Campanula lasiocarpa is a very cold-hardy plant, tolerating winter temperatures down to at least -20°c[
Prefers a moist but well-drained rich sandy loam and a neutral or alkaline soil in sun or partial shade[
]. A rock garden plant, it is difficult to grow in the garden needing a very gritty soil and perfect drainage[
]. It grows freely amongst rocks or in a loose scree, but is very impatient of winter wet[
Slugs are very partial to this plant[
Members of this genus are rarely if ever troubled by browsing deer[
The species in this genus do not often hybridize and so seed can generally be relied upon to come true[
]. This species is self-fertile[
]. Plants produce seed freely in British gardens[
There is at least one named variety, selected for its ornamental value. 'Alba' has white flowers[
]. No more details are given, but the flowers and leaves of this plant should also be edible[
Seed - surface sow spring in a cold frame. The seed usually germinates in 2 - 4 weeks at 18°c. Easy[
]. 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, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the summer or following spring.
