Rhamnus alpina
Safety & Hazards
Species in this genus contain hydroxyanthracene derivatives which have a stimulant laxative effect upon the body, and many species are used traditionally as laxatives. In small doses, and for short periods, these can be safe and effective, but used over long periods they can weaken the body's natural ability to defecate and can have a range of long-lasting negative effects upon the body, including anaemia, malabsorption, haematuria and weight loss. Large single doses can cause severe purging.
Cultivation Details
Rhamnus alpina is a moderately cold-hardy plant, able to tolerate temperatures down to around -20°c when fully dormant[1]. Usually found in calcareous soils in the wild[2].
Propagation
Seed - best sown as soon as it is ripe in the autumn in a cold frame. Stored seed will require 1 - 2 months stratification at 5°c and should be sown as early in the year as possible in a cold frame[1]. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in the greenhouse or cold frame for their first winter. Plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, mid summer in a frame[3]. Cuttings of mature wood of the current year's growth, autumn in a frame. Layering in early spring[4]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Rhamnus+alpina>
