Uses

Edible uses

Fruit - raw or cooked. A pleasant acid flavour, it is nice when added to muesli or porridge[K]. Unfortunately, there is relatively little flesh and a lot of seeds[K]. The fruit is about 10mm long and 6mm wide[5], it ripens in April/May and if the plant is in a sheltered position the crops can be fairly heavy[K].

The leaf is febrifuge and tonic[7]. A decoction of the root and stems is antiphlogistic, antirheumatic, depurative and febrifuge[2][7]. A decoction is used in the treatment of pulmonary tuberculosis, recurring fever and cough in rundown body systems, rheumatoid arthritis, backache, weak knees, dysentery and enteritis[2]. The root and root bark are best harvested in the autumn[6]. Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects[7] and is used as a bitter tonic[6]. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery[7]. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine[7]. Berberine has also shown antitumour activity[7].

Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - best sown as soon as it is ripe in a cold frame[9]. It usually germinates in the spring[K]. 'Green' seed (harvested when the embryo has fully developed but before the seed case has dried) should be sown as soon as it is harvested and germinates within 6 weeks[K]. Stored seed should be sown as soon as possible in late winter or spring. 3 weeks cold stratification will improve its germination, which should take place in 3 - 6 months at 10°c. Prick out the seedlings when they are large enough to handle and grow them on in a cold frame for at least their first winter. Plant them out in late spring or early summer. Division of suckers in spring[9]. Whilst they can be placed direct into their permanent positions, better results are achieved if they are potted up and placed in a frame until established[1]. Leaf cuttings in the autumn.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Thrives in any good garden soil[1]. Grows well in heavy clay soils. Survives under quite heavy tree cover[1], thriving in dense shade[3]. Prefers a semi-shaded woodland position in a damp, slightly acid to neutral humus-rich soil[5]. The fully dormant plant is hardy to about -20°c[4], though the young growth in spring can be damaged by late frosts. Scarcely distinct from M. japonica[1][5], differing mainly in its broader leaflets which are placed closer together on the stem and its erect flower racemes[8]. It is often treated as a subspecies of M. japonica, despite the fact that this species is found in the wild whilst M. japonica is a cultigen and not a wild plant[1][5]. Plants of the two species are often confused in cultivation. The flowers are sweetly scented[8]. Hybridizes freely with other members of this genus.
