Physical Characteristics

An evergreen Perennial growing to 0.3m by 0.3m.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) or semi-shade (light woodland). It requires moist soil and can tolerate drought.

Habitats

Woodland Garden; Dappled Shade; Shady Edge; Deep Shade; Ground Cover; Hedgerow;

Edible Uses

Edible Parts: Leaves.

Leaves - raw or cooked[2, 7, 8, 9, 105]. They can be added to salads or used as a potherb[183]. A fairly bland flavour but the leaves are low in fibre and make an acceptable addition to mixed salads, though their mucilaginous and slightly hairy texture make them less acceptable when eaten on their own[K]. The young leaves make a palatable cooked vegetable[244], though we have found the texture to be somewhat slimy[K]. The plant is an ingredient of the drink Vermouth[244].

Medicinal Uses

Astringent; Demulcent; Diaphoretic; Diuretic; Emollient; Expectorant; Homeopathy; Ophthalmic; Resolvent.

Lungwort has a high mucilage content and this makes it useful in the treatment of chest conditions, being of particular benefit in cases of chronic bronchitis[254]. It combines well with other herbs such as coltsfoot (Tussilago farfara) in the treatment of chronic coughs including whooping cough and can also be taken to treat asthma[254]. The leaves and flowering shoots are astringent, demulcent, diaphoretic, diuretic, emollient, mildly expectorant and resolvent[4, 7, 9, 21, 165]. They are often used for their healing effect in pulmonary complaints[4] and their mucilaginous nature makes them beneficial in treating sore throats[244]. The leaves can also be used externally to stop bleeding[254]. They are harvested in the spring and dried for later use[7]. A distilled water made from the plant is an effective eyewash for tired eyes[7]. A homeopathic remedy is made from the plant[9]. It is used in the treatment of bronchitis, coughs and diarrhoea[9].

Other Uses

Ground cover.

A tolerant and slow growing ground cover plant for open woodland and border edges[197, 200]. Plants should be spaced about 50cm apart each way[208].

Cultivation details

Grows well in any moderately good soil including heavy clay soils[1, 31]. Prefers full to part shade in a moist humus rich soil[200]. Succeeds in the sunless shade of buildings[200]. Plants growing in shady positions tolerate drought if the soil is rich in humus[190]. The leaves tend to wilt in hot weather when the plant is grown in full sun[190]. Hardy to about -20°c[187]. Members of this genus are rarely if ever troubled by browsing deer and rabbits[233]. A valuable early nectar source for bees[200]. There are several named forms, selected for their ornamental value[233]. Hybridizes freely with other members of this genus[200].

Propagation

Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring or autumn or after flowering in early summer if the soil is not too dry[200]. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Cultivars

There are some named forms, selected for their ornamental value. Since we know of no forms that have been selected for their useful properties, we have not listed any cultivars here and in general, unless you require the specific ornamental properties of a cultivar, we recommend you grow the species rather than any cultivars.
