Cultivation Details
Thrives in a deep well-drained humus-rich fertile soil in a sunny position[1]. This species is not very hardy in Britain but it succeeds outdoors in the milder areas of the country[2]. The hardiness of the tree depends upon its provenance in its native habitat[3]. Plants often self-sow in Cornwall[4]. A very ornamental plant[5]. Plants in this genus are notably resistant to honey fungus[1].
Propagation
Seed - best sown as soon as it is ripe in the autumn in a greenhouse. Sow stored seed in early spring in a greenhouse. It usually germinates freely[1]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 5 - 8cm with a heel, mid summer in a frame[5, 1]. Layering[1]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Plagianthus+regius>
