Artemisia japonica
Propagation: Seed - surface sow from late winter to early summer in a greenhouse, making sure that the compost does not dry out[1]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer.
Division in spring or autumn[1].
Basal cuttings in late spring. Harvest the young shoots when about10 - 15cm long, pot up in a lightly shaded position in a greenhouse or cold frame and plant them out when well rooted. Very easy.
Cultivation: Easily grown in a well-drained circumneutral or slightly alkaline loamy soil, preferring a warm sunny dry position[2][1]. Established plants are drought tolerant[1].
This species is not very hardy in the colder areas of Britain, it tolerates temperatures down to between -5 and -10°c[1]. Plants are longer lived, more hardy and more aromatic when they are grown in a poor dry soil[3].
Members of this genus are rarely if ever troubled by browsing deer[4].
Range: E. Asia - China, Japan, Korea.
Habitat: Sunny hills and low elevations in mountains all over Japan[5]. Forest margins, waste areas, shrublands, hills, slopes and roadsides from low elevations to 3300 metres[6].
Edibility: Young leaves - cooked. Used as a vegetable[7].
Medicinal: The leaves are digestive[8]. A decoction of the leaves is said to promote a plump figure, but too much is said to be deleterious and can cause hypertension[7].
The expressed juice of the plant is used in the treatment of vaginitis[8][7]. It is also used to treat skin diseases[9].
Theplant is used for making antitoxifying and antifebrile drugs[6].
Usage: The powder of the dried plant is used as an incense[9].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Seed Ripens: Early Fall-Mid Fall
Flower Type: Hermaphrodite
Known Hazards: Although no reports of toxicity have been seen for this species, skin contact with some members of this genus can cause dermatitis or other allergic reactions in some people[10].
Also Known As: A. mandschurica. A. subintegra. Chrysanthemum japonicum.
