Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers moist soil.

Edible Uses
Edible Parts: Fruit
Edible Uses:
Fruit - raw or cooked. An acid flavour but the fruit is rather nice raw, especially when added to muesli or porridge[K]. Unfortunately, there is relatively little flesh and a lot of seeds[K]. The fruit ripens in early spring and good crops have often been seen on plants growing in sheltered positions[K]. The fruit is produced in large clusters and so is easy to harvest[K].

Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antibacterial Antitumor Dysentery Tonic
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]. The root and root bark are best harvested in the autumn[213].

Cultivation details
An easily grown shrub, it thrives in any good garden soil including heavy clays. Prefers a semi-shaded woodland position in a damp, slightly acid to neutral humus-rich soil. Survives under very heavy tree shade. The fully dormant plant is hardy to about -15°c[184], though the young growth in spring can be damaged by late frosts. Commonly grown as an ornamental plant, there are several named varieties[182]. This plant often produces a good crop of fruit in April and May. It seems that a sheltered position helps to ensure a good crop, as does growing more than one cultivar together and perhaps also one or both of the parents (M. bealei and M. japonica)[K]. The cultivars 'Charity' and 'Lionel Fortescue' have both been seen on a number of occasions with heavy crops[K]. The flowers are very sweetly scented[182].

Plant Propagation
Seed - this is a hybrid species and seed will not come true, though some interesting plants might be produced. The seed is 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. Stems will often root if they are stuck in the ground with most of their leaves removed[182].
