Cultivation Details

HabitPerennial
Growth—

Easily grown in any reasonably good well-drained but moisture retentive soil[2]. Succeeds in sun or semi-shade but flowers better in a sunny position[3]. This plant is unlikely to be very hardy in Britain, though it might succeed outdoors in the milder areas of the country[3].

Propagation

Seed - sow spring in a greenhouse. Germination usually takes place within 1 - 3 months at 10°c. 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 spring[4]. 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/Hypericum+sampsonii>
