Bergenia cordifolia
Propagation: Seed - surface sow in a greenhouse. Make sure that the compost does not dry out. Two weeks cold stratification can speed up germination which usually takes 1 - 6 months at 15°c[1]. Fresh seed, sown as soon as it is ripe in late spring is liable to germinate better than stored seed. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Division in late spring after flowering[2] or in autumn[3]. Very easy, larger divisions can be planted straight into their permanent positions whilst smaller clumps are best potted up and kept in a cold frame until they are growing away well.
Cultivation: Succeeds in full sun or light shade in most soils[1][3] but prefers a deep fertile soil that does not dry out fully[1]. Established plants are drought tolerant according to another report[4]. Grows well in heavy clay soils. Plants are at their best in a medium-heavy soil[5]. Requires a position sheltered from cold drying winds and from the early morning sun. The leaf colour is best when plants are grown in a poor soil in a sunny position[2].
A very ornamental plant, it is hardy to about -20°c[6]. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K].
Plants seem to be immune to the predations of rabbits[7].
This species is closely related to B. crassifolia, and is considered to be no more than a synonym for that species in some new floras[8].
The different species of this genus will hybridise freely when grown near each other[7].
Range: E. Asia - Siberia, Mongolia.
Habitat: Damp rocky woodland and meadows[3].
Usage: A useful ground cover plant, though rather slow to spread[3]. It forms a clump[5].
Tannin is obtained from the bark[9]. On a 10% moisture basis, the roots contain 14.5% tannin and the leaves 10.5%[9].
Soil: Can grow in light, medium, and heavy soils.
In Leaf: Evergreen
Flower Type: Hermaphrodite
Heavy Clay: Grows in heavy-clay soils.
