Uses

Toxic parts

The leaves, and especially the rhizomes, of this species contain an irritating resinous substance called irisin. If ingested this can cause severe gastric disturbances[1]. Plants can cause skin irritations and allergies in some people[2].

Edible uses

Notes

The root is dried and used as a flavouring[3][4].

Unknown part

Material uses

The root is a source of Orris powder which has the scent of violets[2]. It is obtained by grinding up the dried root[5][6][7]. It is much used as a fixative in perfumery and pot-pourri, as an ingredient of toothpastes, breath fresheners etc and as a food flavouring. The root can take several years of drying to fully develop its fragrance, when fresh it has an acrid flavour and almost no smell[5][8]. An essential oil is obtained from the fresh root, this has the same uses as the root[9][10].

The juice of the root is sometimes used as a cosmetic and also for the removal of freckles from the skin[5]. A black dye is obtained from the root[8]. A blue dye is obtained from the flowers[8].

The seeds are used as rosary beads[10].

Medicinal uses(Warning!)

The root is diuretic, emetic, expectorant and mildly purgative[6][11][10]. Another report says that the juice of the fresh root is a strong purge of great efficiency in the treatment of dropsy[5]. In the past, sections of the dried root have been given to teething babies to chew on, though this has been discontinued for hygienic reasons[11]. Roots of plants 2 - 3 years old are dug up after flowering and are then dried for later use[6].

Propagation

Seed - best sown as soon as it is ripe in a cold frame. Stored seed should be sown as early in the year as possible in a cold frame. A sterile plant, it does not produce seed[12]. Division, best done after flowering. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Cultivation

A very easily grown plant that tolerates considerable neglect[12], it prefers a sunny position in a well-drained soil that contains some lime[13][14]. Grows well in dry soils in light deciduous shade[15]. Succeeds in full sun or partial shade[14]. Prefers a pH in the range 6 to 7.5 or higher[16].

Many named varieties have been selected for their ornamental value[15]. The plant is also sometimes cultivated for the essential oil in its root[11]. The plant is sterile and does not produce seed[12].

Members of this genus are rarely if ever troubled by browsing deer or rabbits[12].
