I have grown this sweet smelling plant for several years thinking it was a Sarcococca but comparing this photo to others on Google images I am now having doubts.

Sarcococca Hookeriana aka “Himalayan Sweet Box” is evergreen growing and flowering in light shade.

Sarcococca Confusa aka Christmas Box or Sweet Box are evergreen shrubs with simple, leathery leaves and tiny, fragrant creamy-white flowers in winter or spring, followed by red, purple or black berries.

According to Thompson & Morgan ‘The winter blooms of Sarcococca hookeriana humilis emerge against a backdrop of lustrous, dark green leaves, with a powerful honey scent that will stop you in your tracks. The white, spidery flowers are followed by spherical, glossy black berries. Once established, this versatile, evergreen shrub needs little maintenance and tolerates a wide range of conditions – even difficult spots in dry, shade. A useful plant for borders, shady woodlands, and containers, or grown as a low, informal hedge. Height: 60cm (24”). Spread: 100cm (40”).’
