Physical Characteristics

A decidious Shrub growing to 3m by 3m at a fast rate.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in nutritionally poor soil. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very acid and very alkaline soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It requires moist soil and can tolerate drought. The plant can tolerates strong winds but not maritime exposure.

Habitats

Woodland Garden; Sunny Edge; Dappled Shade; Shady Edge; Deep Shade; Hedgerow;

Cultivars: (as above except)
'Thornless'

Edible Uses

Edible Parts: Fruit; Leaves; Root.

Edible Uses: Tea.

Fruit - raw or cooked[5, 7, 9, 12, 183]. The best forms have delicious fruits and, with a range of types, it is possible to obtain ripe fruits from late July to November[K]. The fruit is also made into syrups, jams and other preserves[238]. Some people find that if they eat the fruit before it is very ripe and quite soft then it can give them stomach upsets[K]. Root - cooked. The root should be neither to young nor too old and requires a lot of boiling[7]. A tea is made from the dried leaves[21] - the young leaves are best[61]. The leaves are often used in herbal tea blends[238]. Young shoots - raw. They are harvested as they emerge through the ground in the spring, peeled and then eaten in salads[244].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Astringent; Depurative; Diuretic; Tonic; Vulnerary.

The root-bark and the leaves are strongly astringent, depurative, diuretic, tonic and vulnerary[4, 7, 9, 165, 254]. They make an excellent remedy for dysentery, diarrhoea, haemorrhoids, cystitis etc, the root is the more astringent[4, 238]. Externally, they are used as a gargle to treat sore throats, mouth ulcers and gum inflammations[238, 254]. A decoction of the leaves is useful as a gargle in treating thrush and also makes a good general mouthwash[7].

Other Uses

Dye; Fibre; Pioneer.

A purple to dull blue dye is obtained from the fruit[168]. A fibre is obtained from the stem and used to make twine[66]. Plants are spread by seed deposited in the droppings of birds and mammals. They often spring up in burnt-over, logged or abandoned land and make an excellent pioneer species, creating the right conditions for woodland trees to move in. The trees will often grow in the middle of a clump of blackberries, the prickly stems protecting them from rabbits[K].

Cultivation details

Easily grown in a good well-drained loamy soil[1, 11, 200]. Succeeds in acid and calcareous soils[186]. Tolerates poor soils[202]. Established plants are drought resistant[132]. Succeeds in sun or semi-shade[1, 11, 200], though it fruits less well in the shade[202]. Plants will also fruit when grown in fairly deep shade or against a north facing wall, though the fruit will ripen later[219]. Plants tolerate quite severe exposure[186]. Hardy to at least -18°c[202]. R. fruticosus is an aggregate species made up of several hundred slightly differing species. The reason for this is that most seed is produced by a non-sexual method (Apomixis) and is therefore genetically identical to the parent plant. On occasions when sexual production of seed takes place the offspring will all be slightly different from the parent plant and will then usually reproduce as a new species by means of apomixy. Modern treatment of this aggregate usually does not use the name R. fruticosus because of the confusion over which species it should apply to, the type species of the aggregate should be called R. ulmifolius[150]. The following members of the aggregate have been highly recommended for their fruit[150]. R. badius. R. cyclophorus. R. gratus. R. nemoralis. R. oxyanchus. R. pyramidalis. R. separinus. R. winteri. The following members are said to be nearly as good. R. balfourianus. R. broensis. R. carpinifolius. R. foliosus. R. fuscoviridis. R. infestus. R. insericatus newbouldianus. R. koehleri. R. largificus. R. londinensis. R. ludensis. R. macrophyllus. R. obscurus. R. pseudo-bifrons. R. rhombifolius. R. riddelsdellii. R. scaber. R. thyrsiflorus. R. vallisparsus. R. vestitus. Plants form dense thickets and this makes excellent cover for birds[186]. They regenerate freely after being cut back[186]. This species is also a good plant for bees and butterflies[24]. This species has 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

'Ashton Cross'

A vigorous and heavy cropping cultivar with thin, thorny canes[253]. The small to medium-size fruits have the true wild blackberry flavour and are produced in mid to late season[253].

'Bedford Giant'

An early fruiting cultivar with long, thorny canes[253]. The large soft fruits have a good flavour and are produced in early to mid season - from late July in southern Britain[253].

'Black Satin'

The canes are sturdy, thornless and easy to train[253]. The fruits are large and glossy with a fair flavour[253].

'Fantasia'

A very vigorous form with large but widely spaced thorns. It produces a heavy crop from August to the end of September[253]. The canes need to be allowed to grow 4.5 metres long for training[253]. The large firm fruits have a good flavour[253].

'Loch Ness'

A thornless cultivar with stout moderately vigorous canes[253]. Easy to train, plants can be grown closer than many cultivars, about 2.4 metres apart[253]. The large fruits have a fair flavour, they are produced in mid to late season[253].

'Sylvan'

A moderately vigorous cultivar with thorny canes that are fairly easy to train[253]. The canes need to be allowed to grow at least 3.6 metres long[253]. One of the earliest fruiting blackberries, ripening from July. It produces heavy crops of large, dark-purple fruits with a good flavour[253].

'Waldo'

This thornless cultivar has weak to moderate cane growth[253]. The fruit is large with a good flavour[253].

Rubus fruticosus

Tue Jun 13 2006

This plant has grown out of control in the undergrowth of our garden and now that we have cut back our shrubs we have found it difficult to control the growth of these thorny canes. They are sprouting up everywhere and we have small children in the garden and are worried. Would a week killer kill these prickly canes off.

Rubus fruticosus

The Jolly Roger Sun May 6 2007

You have no need to worry about your children, these are blackberry vines, not gestapos. Also I would think that if that didn't kill them, it would at least kill week.
