Notes

Fruit - raw or cooked and used in pies, preserves etc[1][2]. The fruit can also be dried for later use[2]. A sweet flavour[3][4][5][6]. The fruit can vary in flavour, the best forms have a large, sweet and well flavoured fruit[2], whilst some forms are large but sour or insipid[7].

Young shoots - raw or cooked like asparagus[2]. They are harvested in the spring as they emerge through the soil and are still tender. A tea is made from the fresh or dried leaves[1][2][8]. The young shoots can be made into a tea, usually mixed with the young shoots of other Rubus species[8].

The half-ripe fruits can be soaked in water to make a pleasant drink[2].

Propagation

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.

Cultivation

Easily grown in a good well-drained loamy soil in sun or semi-shade[11][3][12].

This species is the parent of many hybrid cultivated forms[13], including the loganberry and the primus berry[2]. Some botanists include the cultivated loganberry (treated here as a separate species, R. loganobaccus) under this species[12]. 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[12].

Plants in this genus are notably susceptible to honey fungus[12].
