Cultivation & Habitat

Seed – requires stratification, is best sown in early autumn in a cold frame. Sow stored seed as early as possible in the year in a cold frame and stratify for a month at 3¡c if sowing later than February. 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. Tip layering in July. Plant out in autumn. Division in early spring.
Easily grown in a good well-drained loamy soil in sun or semi-shade[1, 11, 200]. This species is the parent of many hybrid cultivated forms[71], including the loganberry and the primus berry[183]. Some botanists include the cultivated loganberry (treated here as a separate species, R. loganobaccus) under this species[200]. This species is a blackberry 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[200]. Plants in this genus are notably susceptible to honey fungus[200].
