Growth—

This species is hardy to about -15°c according to one report[2], though another says that plants only succeed outdoors in southern and western Britain[3]. Easily grown in a moist humus-rich soil in woodland conditions, succeeding in full or partial shade[4, 2, 5]. Prefers a light sandy loam[3]. Overcollection of this plant from the wild for medicinal purposes is a cause of conservation concern[6]. A very variable species, with a large number of subspecies recognised[7]. Plants are very slow to flower from seed[8]. The individual flowers are very long-lived, lasting for up to 3 months[2, 5].

Propagation

Seed - best sown as soon as it is ripe in late summer in light shade in a greenhouse. Sow stored seed in a greenhouse as soon as it is received. The seed is very slow to germinate. It produces a primary root about 7 months after sowing, this pulls the seed deeper into the soil. Leaves are produced about 4 months later[8]. Sow the seed thinly in fairly deep pots so that the seedlings can be grown on for their first two years without disturbance. Once they have germinated, give them a regular weak liquid feed to ensure that they do not suffer from nutrient deficiency. Once the plants are dormant at the end of their second year of growth, divide them up and put one plant in each pot. Grow them on for at least another year in a shady part of the greenhouse before planting them out into their permanent positions. Division.
