Rhamnus triquetra

Propagation: Seed - best sown in the autumn in a cold frame. Stored seed will require 1 - 2 months cold stratification and should be sown as early in the year as possible in a cold frame or outdoor seedbed. Germination is usually good, at least 80% by late spring. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in the greenhouse or cold frame for their first winter. 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 year's growth, autumn in a frame.

Layering in early spring.

Cultivation: We have very little information on this species and do not know if it will be hardy in Britain. The following notes are based on the general needs of the genus.

Succeeds in any reasonably good soil[1].

Often bears the aecidospore stage of 'crown rust' of oats[2][3].

The species in this genus are notably resistant to honey fungus[4].

Range: E. Asia - Himalayas.

Habitat: Woodlands, 900 - 2400 metres[3][5]. Amongst shrubs at the margins of forests at elevations of 1200 - 3000 metres in Nepal[6].

Medicinal: The bark is astringent and deobstruent[7]. The juice of the bark is used in the treatment of diarrhoea and dysentery[6]. Caution is advised on the use of this plant, see the notes above on toxicity[K].

Usage: Wood - hard, close grained, handsome. Used for turnery, agricultural implements and small carving[3][5]. A good source of charcoal[6].

Pollinators: Insects

Soil: Can grow in light, medium, and heavy soils.

Flower Type: Hermaphrodite

Known Hazards: The bark is toxic[7]. Although no other mention of toxicity has been found for this species, it is possible that other parts of the plant could also be mildly poisonous[8].
