Growth—

Campanula rapunculus is fairly cold tolerant, able to withstand winter temperatures falling to least -15°c[1]. An easily cultivated plant, it prefers a moist but well-drained, rich sandy loam and a neutral or alkaline soil in sun or partial shade[2, 3, 1], though it succeeds in most good soils[3]. Tolerates a pH in the range 4.8 to 7.5. Plants often self-sow in the garden[4]. The species in this genus do not often hybridize and so seed can generally be relied upon to come true[5]. This species is self-fertile[5]. When grown for its edible root, the plant should not be allowed to flower[3]. Plants can be grown in a meadow[1]. Members of this genus are rarely if ever troubled by browsing deer[6].

Propagation

Seed - surface sow May/early summer in situ. The seed usually germinates in 2 - 4 weeks at 18°c[7]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Campanula+rapunculus>
