(aka: Rubus hayata-koidzumii, Rubus calycinoides, Rubus 'Formosan Carpet') We probably get as many requests for Rubus 'Emerald Carpet' as any plant we grow. Where else could you find a durable, evergreen, beautifully-textured groundcover that takes sun or shade? The answer...Taiwan. This selection was made at the University of British Columbia from seed collected by Dick Pearson from the alpine forests (9500' elevation) of Mt. Hehuan in central Taiwan. Thick, heavily textured, sandpaper-like foliage adorns fuzzy creeping stems (5' wide in 3 years). At the onset of cool nights in fall, the foliage of Rubus 'Emerald Carpet' turns a wonderful raspberry color. The small white flowers are insignificant, but that's okay.
Nomenclature:
Many folks now list Rubus pentalobus 'Emerald Carpet' as a selection of Rubus rolfei, which it actually keys to, if you use the poor quality key in Flora of China. When you use the much more accurate Flora of Taiwan key, it keys to Rubus pentalobus. Rubus pentalobus has leaves that are 2-5.5 cm (.8" to 2.5") wide x 2-6 cm (.8" to 2.5") wide, where Rubus rolfsii has much larger leaves that are 5-10 cm (2"-4")wide x 6-12 cm (2.5" x 4.75") wide.
