Plant Profile
Japanese Mugwort (Artemisia princeps) is a rhizomatous perennial herb of the daisy family (Asteraceae), native to Japan, Korea and China. It grows 60-120 cm tall, with deeply lobed, white-felted leaves and dense panicles of small flower heads in autumn. The young leaves are the yomogi of Japanese cooking, pounded into mochi and rice cakes, and the dried leaf is a principal source of moxa for moxibustion.
Science & Biotechnology
Research touching on Artemisia princeps ranges from the botany of the Artemisia group to practical horticulture, including seed handling, propagation and the selection of superior forms. This combination of medicinal and culinary significance has made it one of more culturally documented Artemisia species in East Asian ethnobotany. The practical point for growers is that this plant has been observed in gardens for so long that its behaviour holds few surprises.
Uses & Benefits
Japanese Mugwort brings genuine presence to the garden and earns its keep across the growing season. Its readiness to spread and colonise open ground also gives it a modest role in erosion control on disturbed banks and roadsides within its native range. A plant that has settled in will get along with only routine care.
Japanese mugwort, yomogi, flavors mochi and spring dishes in Japan and serves as moxa; it is a culinary herb with a gentle folk record.
Growing from Seed
Seed is the natural starting point for Japanese Mugwort, and the process is uncomplicated. Sow fine seed onto surface of a loose, well-drained mix without covering it deeply, keeping medium consistently moist. A simple routine works well: sow evenly over the surface and cover lightly in a loose, well-drained seed compost, maintain even moisture, and provide full sun. Prick the seedlings out once they are large enough to handle, grow them on in bright light, and plant out when conditions allow.
