GrowthFast

Rubus loganobaccus is hardy to about -18°c[1]. Easily grown in a good well-drained loamy soil in sun or semi-shade[2, 3, 4]. Tolerates all but the most alkaline soils[1]. Plants dislike exposed windy situations[PFAF]. This species was first established in California in 1883, where it was found growing in the garden of J. Logan as an accidentally crossing of the octoploid blackberry species Rubus ursinus with a tetraploid cultivar of the raspberry (Rubus idaeus)[5, 6]. Often cultivated for its edible fruit in temperate countries, there are some named varieties[7], including forms with thornless stems[4, 5]. 'LY654' is a thornless form with good flavour[4]. The plant usually crops heavily[PFAF]. The plant produces apomictic flowers, these produce fruit and viable seed without fertilization, each seedling is a genetic copy of the parent[4]. Plants in this genus are notably susceptible to honey fungus[4]. Plants are liable to attacks of raspberry cane spot and mildew, otherwise they are one of the most reliable of the fruiting members of this genus[1].

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[4]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn[4].
