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[7]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn[7].

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Easily grown in a good well-drained loamy soil in sun or semi-shade[1][3][7]. 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[7]. The plant produces apomictic flowers, these produce fruit and viable seed without fertilization, each seedling is a genetic copy of the parent[7]. Sometimes cultivated for its edible fruit, it is a very vigorous and productive plant[9]. There is at least one named variety. 'Oregon Cutleaf Thornless' is high yielding with good flavoured fruits and no prickles on the stems, thus making it easier to harvest[5]. Plants in this genus are notably susceptible to honey fungus[7].
