Cultivation details

Easily grown in a good well-drained loamy soil in sun or semi-shade[1, 11, 200]. Plants are not reliably hardy in Britain[1] and are damaged by prolonged frosts[11, 200], but they can succeed outdoors in the milder areas of the country[166, 182]. Closely related to R. australis[1]. The stems are thornless when they are mature[200]. Dioecious, male and female plants must be grown if fruit and seed is required. Plants in this genus are notably susceptible to honey fungus[200].

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 is best sown as early as possible in the year. Prick out the seedlings when they are large enough to handle and grow on in a cold frame. Plant them out into their permanent positions in late spring of the following year. Cuttings of half-ripe wood, July/August in a frame[200]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn[200].
