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[9]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn[9].
Cultivation

Easily grown in a good well-drained loamy soil in sun or semi-shade[1][3][9]. Hardy to about -15°c[7]. Another report suggests that the plant will only succeed outdoors in the mildest parts of the country[9]. The plant has ornamental white canes but it needs plenty of space and is not a good neighbour because of its prickly stems[6]. This species is a raspberry with biennial stems, it produces a number of new stems each year from the perennial rootstock, these stems fruit in their second year and then die[9]. Plants in this genus are notably susceptible to honey fungus[9].
