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[5]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn[5].

Cultivation

Easily grown in a good well-drained loamy soil in sun or semi-shade[1][3][5]. Closely related to R. kuntzeanus[3]. 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[5]. Plants in this genus are notably susceptible to honey fungus[5].
