Cultivation Details
Easily grown in a good well-drained loamy soil in sun or semi-shade[1, 2, 3]. Rubus species in general grow well on a variety of barren, infertile soils - this species tolerates a wide range of soil textures and pH but requires adequate soil moisture for good growth[4]. It appears to be tolerant of periodic flooding by brackish or fresh water[4]. This species is the parent of many hybrid cultivated forms[5], including the loganberry and the primus berry[6]. Some botanists include the cultivated loganberry (treated here as a separate species, Rubus loganobaccus) under this species[3]. Plants are tolerant of fire - top growth is usually killed but the plant resprouts rapidly from the roots[4]. A dioecious species, both male and female plants are required if fruits and seed are to be produced[3]. Plants in this genus are notably susceptible to honey fungus[3]. Of agricultural significance, this species is a parent of some important cultivars, including the loganberry and the boysenberry[7].
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 late winter. 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. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Rubus+ursinus>
