Rubus amabilis

Rubus amabilis is a deciduous raspberry shrub in the rose family. It comes from eastern Asia, from China to the Himalayas. Its range includes several Chinese provinces and Nepal. It is not native to Britain or Ireland. In the wild, it grows in forests, thickets, and mountain valleys. It also grows beside ditches, roads, and woodland edges. Habitat records span about 3,280–12,470 feet [1,000–3,800 metres] above sea level.

The shrub reaches about 6.6 feet [2 metres] in height. A lasting rootstock sends up new stems each year. Each stem lives for two years. It bears fruit in its second year, then dies. This cycle renews the plant without replacing the rootstock. The plant loses its leaves for winter. The supplied species account gives no detailed leaf or bark traits. Its ornamental value makes it a choice for woodland gardens. Suitable sites include sunny woodland margins and spots with dappled shade.

Flowers appear from June to July. Each flower has both male and female organs. Insects carry pollen between the flowers. The seeds ripen from July to August. The fruit measures about 0.6 inches [16 millimetres] across. It has a sweet taste and a good flavour. Gardeners can eat it fresh or use it in cooked dishes. The fruit also yields a purple to muted blue dye. Plants For A Future lists no known medicinal uses. It also reports no known hazards, rather than a proven safety assessment.

Grow this shrub in sun or light shade. It prefers moist soil that drains well. A loam rich in humus suits it well. The account also lists sandy and clay soils as suitable. It accepts mildly acid, neutral, and mildly alkaline conditions. Plants For A Future describes it as easy to grow. It lists USDA zones 5–9 and cold tolerance near −4°F [−20°C]. The same source does not flag it as weedy.

Seed and division offer ways to raise more plants. Fresh seed is best sown in a cold frame in early autumn. Stored seed needs a month of cold treatment near 37°F [3°C]. Sow that seed early in the year. Grow young seedlings in a cold frame before planting out. Move them to their final sites the next late spring. Divide established plants in early spring or just before autumn leaf fall.
