Phellodendron amurense
Safety & Hazards
The bark contains berberine, a bitter-tasting alkaloid which, in small quantities, has a range of effective medicinal applications but, in excess, can cause vomiting, lowered blood pressure, reduced heart rate, lethargy, and other ill-effects.
Cultivation Details
Phellodendron amurense is a very cold-hardy plant, being able to tolerate temperatures down to around -30°c or more when fully dormant. The young growth is much more tender, however, and is liable to damage from late spring frosts. The plant grows best in areas with long hot summers, which allow it to fully ripen its wood and make it more tolerant of winter cold[1, 2, 3]. Prefers a moisture retentive well-drained deep rich loam in full sun[1, 3]. Prefers a neutral to alkaline soil[4]. Succeeds in shallow chalky soils[5]. Plants are gross feeders and require a rich soil if they are to perform well[1]. The plant grows well in cities, being tolerant of many urban air pollutants[6]. The leaves are aromatic[2]. The foliage and fruits are unpleasantly aromatic when bruised[6], This species is occasionally cultivated fo its use as a dye and a medicine in Asia[7, 8] and also for timber in S.E. Europe[9]. A dioecious species - both male and female forms must be grown if fruit and seed are required.
Propagation
Seed - best sown in the autumn in a cold frame[3]. Stored seed requires 2 months cold stratification, sow in late winter in a cold frame[10, 11]. Germination is usually good. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the cold frame for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, mid summer in a frame. Pot up in autumn and over winter in a cold frame. Fair to good percentage[10]. Root cuttings - obtain in December and store in leafmold in a warm place for 3 weeks. Cut into 4cm lengths and plant horizontally in pots. Grow on in a warm greenhouse. Good percentage[10].
