Rubus rolfei, known as creeping raspberry, crinkle-leaf creeper,[1] or Taiwanese creeping bramble, is a low-growing member of the genus Rubus and is related to the blackberry and raspberry. It is common in the horticultural trade.[2] The species is originally from Taiwan where it grows at high elevations.[3]
Like other plants in this genus, creeping raspberries bear aggregate fruits. Each "fruit" is actually a cluster of small fruit-like parts (pistils) connected together into one mass.
Creeping raspberry fruits are similar in appearance to blackberries or red raspberries, but differ in that their color is yellow to orangish-red. The edible fruits follow white flowers which are borne in early summer.
Plants are sometimes used to form a low growing, non-invasive, semi-evergreen to evergreen ground cover.[4] [3] Cultivars such as 'Emerald Carpet' are common in the plant trade.[3]
The names Rubus pentalobus, R. hayata-koidzumii and R. calycinoides are considered taxonomic synonyms of Rubus rolfei. Rubus calycinoides, as described by Otto Kuntze, is a distinct species.
