How to Identify

A deciduous shrub growing 0.6m tall by 1m wide, hardy to UK zone 5 and not frost tender. Flowers in July with seed ripening in August. Hermaphroditic and insect-pollinated. Tolerates light sandy, medium loamy, and heavy clay soils with good drainage. Grows in mildly acidic to basic soil pH, semi-shade or full sun, with moist soil preference. Effective groundcover that dies back over winter.

How to Grow

Easily grown in a good well-drained loamy soil in sun or semi-shade. Sometimes cultivated for its edible fruit and occasionally naturalized in Europe. Plants spread freely when in a suitable site and are apt to become invasive. The plant adopts an almost herbaceous habit and is botanically a sub-shrub, only a small amount of woody stem persists overwinter. Plants in this genus are notably susceptible to honey fungus. An evergreen.

Propagation: Seed requires stratification and is best sown in early autumn in a cold frame. Stored seed needs one month stratification at about 3°C and should be sown as early as possible in the year. Prick out seedlings when large enough to handle and grow on in a cold frame, then plant out into permanent positions in late spring of the following year. Cuttings of half-ripe wood can be taken in July/August in a frame. Tip layer in July and plant out in autumn. Divide in early spring or just before leaf-fall in autumn.

Medicinal Uses

None known.

Other Uses

A purple to dull blue dye is obtained from the fruit. The plant makes good ground cover for a sunny position or light shade, spreading freely once established, though it dies back over winter and can allow other species to invade during that period.

Rubus illecebrosus is a red-fruited species of Rubus that originally came from Japan (where it is called バライチゴ, literally "roseberry"), but is also very popular in some European countries like Lithuania. Common names include balloon berry and strawberry raspberry. It has become sparingly naturalized in scattered locations in Canada, the United States, and South America. Rubus illecebrosus is a thorny shrub up to 150 cm (5 ft) tall. Leaves are pinnately compound. Flowers are produced either one at a time or in clumps of 2–3, each with 5 petals up to 18 mm (23⁄32 in) long (longer than those of most related species). Fruits are also unusually large for the genus, each oblong, red, up to 2 cm (3⁄4 in) long with 50–100 drupelets.
