Physical Characteristics

An evergreen shrub growing to 2m by 2m . It is hardy to zone 6 and is frost tender. It is in leaf all year, in flower from January to March, and the seeds ripen from April to May. The scented flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. We rate it 3/5 for edibility and 2/5 for medicinal use.

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) semi-shade (light woodland) or no shade. It requires moist soil.

Habitats and Possible Locations

Woodland, Sunny Edge, Dappled Shade, Shady Edge, Deep Shade.

Edible Uses

Fruit.

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[200], it ripens in April/May and if the plant is in a sheltered position the crops can be fairly heavy[K].

Medicinal Uses

Disclaimer

Antibacterial Antiphlogistic Antirheumatic Cancer Depurative Febrifuge Tonic.

The leaf is febrifuge and tonic[218].
A decoction of the root and stems is antiphlogistic, antirheumatic, depurative and febrifuge[147, 218]. 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[147]. The root and root bark are best harvested in the autumn[213].
Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects[218] and is used as a bitter tonic[213]. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery[218]. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine[218]. Berberine has also shown antitumour activity[218].

Other Uses

None known

Cultivation details

Thrives in any good garden soil[11]. Grows well in heavy clay soils. Survives under quite heavy tree cover[11], thriving in dense shade[182]. Prefers a semi-shaded woodland position in a damp, slightly acid to neutral humus-rich soil[200].
The fully dormant plant is hardy to about -20° c[184], though the young growth in spring can be damaged by late frosts.
Scarcely distinct from M. japonica[11, 200], differing mainly in its broader leaflets which are placed closer together on the stem and its erect flower racemes[245]. 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[11, 200]. Plants of the two species are often confused in cultivation.
The flowers are sweetly scented[245].
Hybridizes freely with other members of this genus.

Propagation

Seed - best sown as soon as it is ripe in a cold frame[78]. 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[78]. 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[11].
Leaf cuttings in the autumn.

Scent

Flowers: Fresh: The flowers are sweetly scented[245].
