Cultivation Details

Growth—

Prefers a moist, rich, well-drained soil and some shade[1, 2]. Prefers woodland conditions or a cool moist shady border[3, 4]. Plants prefer a dry period when dormant in the summer[5].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[2, 4]. A short period of cold stratification may improve the germination of stored seed which should be sown in spring in a cold frame. The seed usually germinates in 1 - 12 months at 15°c[2]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in early spring or September. Autumn is best[1]. 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 spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Dodecatheon+hendersonii>
