Hypericum patulum

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.

Cuttings of half-ripe wood 10 - 12 cm with a heel, July/August in a frame. Plant out in the following spring[1].

Cuttings of mature wood, 12 - 17cm with a heel, October/November in a sheltered position outdoors. Plants root by the spring. Good percentage[2].

Cultivation: Easily grown in any reasonably good well-drained but moisture retentive soil[3]. Succeeds in sun or semi-shade but flowers better in a sunny position[1].

This species is only hardy to about -5°c but plants can resprout from the base if they are cut back by cold[4].

Plants in this genus are notably resistant to honey fungus[1].

Range: E. Asia - W. China, Japan, Himalayas.

Habitat: Shady ravines, sometimes on rocks[5]. Open hillsides, 1500 - 2400 metres in the Himalayas[6].

Medicinal: The seeds are aromatic and stimulant[7].

Usage: Plants are sometimes grown as a hedge[6].

Wood - close grained, moderately hard[6].

Pollinators: Insects

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

In Leaf: Evergreen

Seed Ripens: Early Fall-Late Fall
