Potentilla cryptotaeniae

Propagation: Seed - sow early spring or autumn in a cold frame. 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. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Cultivation: We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of this country. The following notes are based on the general needs of the genus.

Easily grown in a well-drained loam, preferring a position in full sun but tolerating shade[1]. Prefers an alkaline soil but tolerates a slightly acid soil[2].

Members of this genus are rarely if ever troubled by browsing deer[3].

Range: E. Asia - N. China, Japan.

Habitat: Found in mountains all over Japan[4]. Valleys, ravines, meadows, grassland and forest edges at elevations of 1000 - 2500 metres in China[5].

Medicinal: Anthelmintic, antidote, salve, skin, vulnerary[6]. Used in the treatment of venereal sores[6].

Pollinators: Insects

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

Seed Ripens: Mid Summer-Early Fall

Flower Type: Hermaphrodite

Known Hazards: One report says that the plant is very poisonous but gives no details[6].
