Overview

Sarcococca ruscifolia is an evergreen shrub reaching 3-5 feet (0.9-1.5 m) tall with a spread of 3-5 feet (0.9-1.5 m) and a dense, arching, mounding habit—denser and more rounded than S. hookeriana. Native to central and western China, it produces broadly ovate, glossy, dark green leaves 1.5-3 inches (4-8 cm) long with a pointed tip—broader and more ruscus-like (ruscifolia = ruscus-leaved) than S. hookeriana. Tiny, petal-less, creamy-white, intensely fragrant flowers cluster in the leaf axils in January-March. Glossy deep red berries follow and persist through winter—the red (versus black) berries distinguish this from S. hookeriana. Growth rate is slow. Hardy to zone 7. Non-suckering—stays as a single clump. The dense arching form, winter fragrance, and persistent red berries make this the showier species.

Native Range

Sarcococca ruscifolia is native to central and western China—Hubei, Sichuan, Yunnan—in understory of moist forests at 3,000-7,000 feet (900-2,100 m).

Suggested Uses

Planted in shade gardens, under trees, along north-facing walls, or as a low evergreen hedge at 3-4 foot (0.9-1.2 m) spacing. Intensely fragrant winter flowers Jan-Mar. Red berries—showier than black-berried species. Non-suckering—neater than S. hookeriana. Dense evergreen mound. Slow growing. Zone 7—slightly less cold-hardy. Not suitable for full sun, dry soils, or exposed sites.

How to Identify

Distinguished from S. hookeriana var. hookeriana by the broader, ovate (versus narrow lance-shaped) leaves, the red (versus black) berries, the non-suckering (versus suckering) habit, and the denser mounding (versus upright) form. The red-berried sweet box—broader ruscus-like leaves, non-suckering dense mound, red berries, intense winter fragrance, Chinese.
