Cultivation Details

HabitPerennial
Growth—

Succeeds in any moderately fertile retentive soil in a sunny position[1]. Tolerates a wide range of soil types[1]. Established plants are drought resistant[2]. This species is not hardy in all parts of Britain, it tolerates temperatures down to between -5 and -10°c[1]. Plants come into growth in the autumn and die down in mid-summer[2]. Plants spread by means of underground tubers and can be invasive[2]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[3]. At least one named variety has been selected for its ornamental value[1]. 'Charlesii' has a low spreading habit[1].

Propagation

Seed - sow spring in a cold frame or as soon as it is ripe in the summer. Division in late summer or early autumn. 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/Geranium+tuberosum>
