Campanula fenestrellata is a fairly cold-hardy plant, able to tolerate winter temperatures falling to at least -15°c so long as the soil is very well drained[1]. Prefers a moist but well-drained rich sandy loam and a neutral or alkaline soil in full sun though it also tolerates partial shade[2, 1, 3]. Plants are very drought-tolerant and can be grown on a dry stone wall[1], they also succeed in poor soils[4]. The species in this genus do not often hybridize and so seed can generally be relied upon to come true[4]. The plants are self-fertile[4]. Members of this genus are rarely if ever troubled by browsing deer[5].

Propagation

Seed - surface sow spring in a cold frame. The seed usually germinates in 2 - 4 weeks at 18°c[6]. 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[2]. 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[1]. Very easy, the plant can be divided at almost any time of the year[4].
