How to Identify
A shrub. It grows 3-4 m tall. There are a few curved prickles. The leaves are simple and 5-11 cm long by 5-10 cm wide. There are many flowers in a group and the flowers are 1 cm across. The petals are white. The fruit are aggregate and purplish black. They are 1-1.5 cm across.
How to Grow
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors in many parts of the country. The Latin name might be mis-spelt - another report says that it is R. tephrodes. The following notes are based on the general needs of the genus. Easily grown in a good well-drained loamy soil in sun or semi-shade. Plants in this genus are notably susceptible to honey fungus.
Propagation: Seed requires stratification and is best sown in early autumn in a cold frame. Stored seed requires one month stratification at about 3°c and should be sown as early as possible in the year. Prick out seedlings when large enough to handle and grow on in a cold frame, then plant out into permanent positions in late spring of the following year. Cuttings of half-ripe wood can be taken in July or August and rooted in a frame. Tip layer in July and plant out in autumn. Division can be done in early spring or just before leaf-fall in autumn.
Medicinal Uses
The leaves and root are astringent and styptic, and stimulate the circulation. A decoction of the leaves and roots is used in the treatment of amenorrhoea, diarrhoea, dysentery, myalgia, and related conditions.
Other Uses
A purple to dull blue dye can be obtained from the fruit.
