Cultivation Details

HabitDeciduous Shrub

Growth—

Easily grown in a good well-drained loamy soil in sun or semi-shade^{[1, 2, 3]}. Very closely related to Rubus candicans^[4]. Plants always produce semi-infertile fruits^[5]. Plants in this genus are notably susceptible to honey fungus^[3].

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, mid summer in a frame^[3]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn^[3].
