Notes

Fruit - raw or cooked[1][2][3]. An acid flavour but it is rather nice raw, especially when added to muesli or porridge[K]. Unfortunately, there is relatively little flesh and a lot of seeds[K]. Too acid for most tastes but they are very good in jams, jellies, pies etc[4]. They can also be used to enhance the flavour of bland fruits or made into a refreshing lemon-flavoured drink[4]. The fruit is about 8mm in diameter[5]. Young tender leaves - cooked. Simmered in a small amount of water and eaten as a snack[4].

Leaves

Material uses

A yellow dye is obtained from the inner bark of the stem and roots[6][3][7].

Dark green, violet and dark blue-purple dyes are obtained from the fruit[8]. A green dye is obtained from the leaves[8].

Plants can be grown as a ground cover, spaced about 30cm apart each way[9]. They are very slow to spread[9] and so will need weeding for their first few years after planting[K].

Medicinal uses(Warning!)

The root is alterative and tonic[10]. It improves the digestion and absorption and is recommended in the treatment of psoriasis, syphilis and impure blood conditions[10][7]. A decoction of the peeled and chopped root bark has been used as a wash in treating arthritis and as an eyewash for red itchy eyes[7].

The fruit is an excellent safe and gentle laxative[7].

Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects[11] and is used as a bitter tonic[12]. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery[11]. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine[11]. Berberine has also shown antitumour activity[11]. The root and root bark are best harvested in the autumn[12].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[13]. 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[13]. 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[14].

Leaf cuttings in the autumn.

Cultivation

An easily grown plant, it thrives in any good garden soil[14][5] but also succeeds in poor dry ones. Another report says that it is best on a lime-free soil[15]. Grows well in heavy clay soils. Prefers a sunny position[2] but succeeds in heavy woodland shade[K].

Hybridizes freely with other members of this genus. Plants are growing and fruiting well at Wakehurst Place in Sussex, but they do not generally do well in Britain[14].

Resistant to honey fungus[16].
