Growth—

Prefers a well-drained sandy loam with some peat[1] and a sunny position[2]. It avoids wet or rich soils[3]. Plants are not easy to grow in a garden[4]. The flowers only open in fine weather and close at midday[4]. Although the growing plant is scentless, if the cut stems are immersed in warm water for 24 hours a most penetrating odour will be observed on distillation[5]. A very variable plant, some botanists divide it into a number of separate species[4].

Propagation

Seed - sow late winter to May in situ or as soon as it is ripe in situ[6]. Germination is usually rapid. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Centaurium+erythraea>
