Hypericum erectum
Propagation: Seed - sow spring in a greenhouse and only just cover the seed. Germination usually takes place within 1 - 3 months at 10°c. 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 clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
Cultivation: Easily grown in any reasonably good well-drained but moisture retentive soil[1]. Succeeds in sun or semi-shade but flowers better in a sunny position[2].
One report says that the plant is vigorous but not quite hardy in Britain[1]. This seems to be a mistake, other reports say that it is hardy to zone 6, tolerating winter temperatures down to -15°c or lower[2].
Range: E. Asia - China, Japan, Korea.
Habitat: Grassy places and thin woods in hills and mountains all over Japan[3]. Grassy slopes at elevations of 400 - 2300 metresin China[4].
Edibility: Leaves and stems[5][6]. No more details.
Medicinal: The leaves and flowering tops are galactogogue[7].
The stems are rich in tannin and are used in the treatment of arthritis, lumbago, neuralgia and rheumatism[7].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Seed Ripens: Late Summer-Early Fall
Flower Type: Hermaphrodite
