How to Identify
A herb. It grows 15 cm tall. It has rhizomes or underground stems. They are 3-5 mm thick. The stem is erect. There are 7-9 leaves which are alternate. The leaf stalk is very short. The leaf blade is oval or oblong and 5.5-8.5 cm long by 1.5-4 cm wide. It tapers to the tip. The flowering stalk usually has one flower. The flowers hang down. The fruit are berries which are blue-black. They are about 1 cm across with 5-6 seeds.
How to Grow
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. This species is hardy to about -20°c. Closely related to P. hirtum. Closely allied to P. odoratum. Plants are often mistakenly grown as P. falcatum. The rhizomes are slender and creeping, the plant forming spreading colonies. 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.
Medicinal Uses
The roots are antiperiodic, antirheumatic, demulcent, refrigerant, sedative, sialagogue, and tonic.
