of coughs and toothache[257]. An infusion of the roots has been used as a

Cultivation details
Easily grown in a good well-drained loamy soil in sun or semi-shade[1,
11, 200].
Sometimes cultivated, especially in N. America, for its edible fruit[183],
it is a parent of many named varieties[1, 34].
This species is a raspberry 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[200].
Plants in this genus are notably susceptible to honey fungus[200].
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[200].
Tip layering in July. Plant out in autumn.
Division in early spring or just before leaf-fall in the autumn[200].
Cultivars
- 'Plum Farmer' 'Farmer'
- A large fruit with a firm flesh of high quality, it ripens very quickly and the entire crop can be harvested in 2 - 3 pickings[183].
The bush is hardier than most cultivars of this species, it is drought resistant, immune to curl virus but susceptible to anthracnose[183].
- 'Lowden'
- An extremely large fruit with a juicy, sweet flesh of excellent flavour[183]. It is of especially good quality for canning[183]. Ripens late[183].
An upright, quite vigorous, productive, very winter-hardy plant, it is resistant to anthracnose[183].
- 'John Robertson'
- A large, plump fruit with a medium firm flesh, it is juicy and of very good quality[183].
A productive bush, it is one of the hardiest cultivars of this species and crops reliably as far north as Canada[183].
- 'Jewel'
- A large, attractive fruit, the flesh is firm and flavourful, of high quality and ripening in mid-season[183].
A vigorous and productive bush, it is winter hardy and is not susceptible to any serious disease, though is slightly susceptible to mildew[183]. It is considered to be an improvement over 'Bristol'[183].
- 'Haut'
- The medium-size fruit is very sweet with a firm, cohesive flesh, it is of excellent quality and ripens over a longer period than other cultivars of this species[183].
A vigorous, high-yielding plant, it is more productive than 'Bristol'[183]. It is disease-resistant[183].
- 'Black Hawk'
- The large fruit is up to 2cm in diameter, it has a firm flesh with little or no tendency to crumble and a sweet to mildly acid flavour[183]. Ripening in mid-season, it is of excellent quality fresh, frozen or processed[183].
A vigorous, hardy bush that yields extremely well, it does not sucker (this probably means that it does not spread far from the original clump, it has to produce suckers each year in order to maintain itself[K]) and is somewhat resistant to anthracnose[183].
- ''Allen
- The large, attractive fruit is very sweet with a firm flesh[183]. It ripens in mid-season, with a lot of the crop coming ripe at the same time[183]. It is excellent for jam[183].
A good all-round cultivar, though it is not outstanding in any way[183]. A vigorous, productive bush, it is somewhat resistant to mildew[183].
