Propagation
Sow fresh seed during autumn or spring in pots and place in a cold frame to germinate.
Take semi hardwood cuttings from late summer to autumn.

Culture
This plant is responsive to a light prune after flowering to encourage a bushy habit and develops well if not over water or fertilise.

Botanic information
Leaf: The pinnate leaves are covered in fine whitish pubescence and divided into tiny oblong leaflets. They are crowded along the stems alternately or spirally and have a short flattish petiole. When crushed the leaves are aromatic and are used in herbal remedies.

Flower: The radiate flowers have no ray florets and the tiny tubular disk florets are arranged in a dense head up to 12mm (¼in) wide. They are held above the foliage in a slender pubescent scape that is up to 150mm (6in) tall and appears during summer. 

Fruit: The small achene has no pappus and the seed heads are normally removed during cultivation. The small seeds are viable but the plant is commonly reproduced vegetatively.

Note
This plant has been used as an herbal remedy for digestion, menstrual problems, worms and jaundice. Externally it is applied to stings, wounds and for skin inflammations since 1653. Dried leaves are also blended with Tussilago farara for herbal tobacco.
