The climbing raspberry ( Rubus bambusarum Focke , Syn .: Rubus henryi var. Bambusarum (Focke) Rehder ) is a species of the genus Rubus within the rose family (Rosaceae).
description
The climbing raspberry grows as an evergreen, creeping or climbing, woody plant. The up to 6 meters long stem axes have curved spines. The 7 to 13 centimeter long leaves are palmate, three to five parts (palmat) pinnate with almost sessile, 1 to 3 centimeters wide sections. The leaflets are pointed and their edges are inconspicuously serrated. The leaves are somewhat leathery, the upper surface of the leaves is tomentose when young, later balding, glossy dark green and the underside of the leaf is gray or yellowish-gray tomentose (tomentos). The flowers stand together in racemose inflorescences . The radial symmetry flowers have a diameter of up to 2 centimeters. The five petals are light red to dark red. The black-red drupes are less noticeable than the flowers.
The species can be distinguished from the similar and closely related Rubus henryi , also sometimes referred to as the climbing raspberry, by its leaves. In Rubus henryi these are undivided, but incised almost down to the base of the leaf palmatically, in Rubus bambusarum with a blade that is divided down to the base, i. H. the leaf surface is divided into oval-lanceolate individual leaflets.
The number of chromosomes is 4n = 28.
Occurrence
The climbing raspberry thrives in bamboo forests in the Chinese provinces of Guizhou , Hubei , Shaanxi and Sichuan . It grows in forests and clearings at sea levels between 1000 and 3000 m . The species is endemic to China.
Culture conditions
The climbing raspberry occurs up to winter hardiness zone 7, which means temperatures between -18 and -12 ° C can be withstood without damage.
The species is not very common as a cultivar in Europe. It prefers deep and moist soils. A partially shaded location is also best for you. In Central Europe, the plant should only be planted in warmer and protected locations. In severe frosts, the shoot axes can die, but sprout again from the base. The plant below the Agroscope research station in Wädenswil withstood the cold temperatures in February 2012 without damage. The fruits are considered to be of relatively low quality, the plant is more often used ornamentally because of its foliage. In China the young leaves are used as tea.
The climbing raspberry is one of the spreading climbers and needs a climbing aid. This evergreen plant can be used as a ground cover and climbing plant. Climbing raspberries are recommended for greening scaffolding, pergolas, bushes and resistant trees.
It blooms on perennial stems and should therefore not be cut back until it is tapered. The climbing raspberry grows moderately.
The species can be propagated via seeds and wood cuttings. The rooting of the cuttings is most successful in the greenhouse.
