Berberis sibirica is a deciduous Shrub growing to 0.6 m (2ft). It is not frost tender. It is in flower from June to July. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. The plant is self-fertile. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay and nutritionally poor soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil.
Height (m): 0.6
Where it is found
Amongst rocks on stony and desert slopes and rock streams, usually in low mountain zones.

Medicine

Berberine, universally present in rhizomes of Berberis species, has marked antibacterial effects. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine. Berberine has also shown antitumour activity.
Antibacterial: Kills bacteria.
Cancer: Used in the treatment of cancer.
Dysentery: Used in treating dysentery - an infection of the intestines that causes diarrhoea containing blood or mucus.

How it is grown
Prefers a warm moist loamy soil but it is by no means fastidious, succeeding in thin, dry and shallow soils. Grows well in heavy clay soils. Succeeds in full sun or light shade. Hybridizes freely with other members of this genus. Plants can be pruned back quite severely, they resprout well from the base.
Propagating it: Seed - best sown as soon as it is ripe in a cold frame, when it should germinate in late winter or early spring. Seed from over-ripe fruit will take longer to germinate, whilst stored seed may require cold stratification and should be sown in a cold frame as early in the year as possible. The seedlings are subject to damping off, so should be kept well ventilated. When the seedlings are large enough to handle, prick them out into individual pots and grow them on in a cold frame. If growth is sufficient, it can be possible to plant them out into their permanent positions in the autumn, but generally it is best to leave them in the cold frame for the winter and plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, July/August in a frame. Cuttings of mature wood of the current season's growth, preferably with a heel, October/November in a frame.
