Division in spring or autumn. Basal cuttings in late spring. .
Harvesting: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
Phytochemistry:26 terpenoids (21 guaiane-type sesquiterpenes, 3 germacrane-type sesquiterpenes, 1 muurolane-type sesquiterpene, and 1 diterpenoid), 16 sesamin-type lignans, 9 flavonoids, 3 steroids, and 3 alkaloids.

Uppermost leaves and bracts sessile, pinnatisect or entire, leaves or lobes elliptic-lanceolate or lanceolate.
Histology:Synflorescence a long, narrow panicle to 10-30 × 5-10 cm; branches ± erect, 5-10 cm, remote. Capitula many, remote, pedunculate or ± sessile, subtended by linear bracteoles. Involucre hemispheric or subglobose, (3-)4-6 mm in diam.; receptacle hemispheric, densely white pubescent. Marginal female florets 20-30 in (1 or)2 series; corolla conical, (2-)4-toothed.
