Sarcococca confusa Sealy, J. Roy. Hort. Soc. 74: 302 1949.;
Sarcococca confusa (sweet box) is a species of flowering plant in the family Buxaceae, probably native to western China.
It is an evergreen shrub growing to 2 m (7 ft) tall by 1 m (3 ft) broad, with glossy green ovate leaves and honey-scented  white flowers in winter, followed by glossy black spherical fruits, 5 mm in diameter.
It is a very adaptable and reliable shrub that is easily grown in many situations, including dense shade with very dry soil. It will however grow in full sun, even though the foliage appears to “bleach” a little. The soil should be kept damp if grown in sun or part shade.
The shrub is midwinter flowering with a delightful sweet scent.
The small black berries are eaten by birds which disperse the seeds.
