Cultivation

Prefers a fertile humus rich moisture retentive well-drained soil in cool shade or semi-shade. Plants are intolerant of heat and drought but tolerate most other conditions. Thrives in dry shade as long as the soil is rich in humus, the plant is also fairly drought tolerant. Requires a mulch protection for the roots in areas where winter temperatures go below -10°c. The rhizomes are shortly-creeping, the plant forming clumps. This species is often grown mistakenly as P. pumilum. P. humile is often mistakenly grown as this species. Members of this genus are rarely if ever troubled by browsing deer or rabbits. Young shoots are very attractive to slugs. Hybridizes with other members of this genus.

Propagation

Seed is best sown as soon as it is ripe in early autumn in a shady part of a cold greenhouse. Stored seed should be sown as early in the year as possible. Germination can be slow, seedlings may not come true to type, and it takes several years for plants to reach a good size. When large enough to handle, prick seedlings out into individual pots and grow on in a shady position in the greenhouse for at least the first winter. Plant out into permanent positions in late spring or early summer, after the last expected frosts. Division can be done in March or October. Larger divisions can go directly into permanent positions, while smaller divisions are better potted up and grown on in light shade in a cold frame until well established before planting out in late spring or early summer.

Other Uses

Miscellaneous uses are noted but not specified.
