History

Originally from Taiwan where it grows at high elevations.[2]

Uses

Plants are sometimes used to form a low growing, non-invasive, semi-evergreen to evergreen ground cover.[3][2]

Fruit/flower

Like other plants in this genus, creeping raspberries bear aggregate fruits. What this means is that 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.[3]

Pests/diseases

There are no known pests or diseases which affect the creeping raspberry.[2][3]

This plant can be susceptible to overwatering, however, which can cause root rot in wet or heavy soil and good drainage is important.

Other names

The names Rubus pentalobus[4] and Rubus rolfei[5] are sometimes used in place of R. hayata-koidzumii or R. calycinoides. There are a number of other common names including "Crinkle-leaf Creeper",[4] "Taiwanese Creeping Rubus", and "Creeping Bramble",[2] but the plant is also often simply referred to by cultivar names such as 'Emerald Carpet'.[2]
