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[6]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn[6].

Cultivation

Easily grown in a good well-drained loamy soil in sun or semi-shade[1][3]. Requires a shady position[6]. Plants are not fully hardy in all parts of the country[7]. A scrambling climbing plant, supporting itself by means of hooked prickles[5]. Any pruning is best carried out in spring and consists of cutting out some of the old and dead growth from the base[7]. Plants produce numerous new shoots from their base each year, these shoots generally flowering and fruiting in their second year[7]. Plants in this genus are notably susceptible to honey fungus[6].
