Sarcococca Sweet Box, Christmas Box (Buxaceae)PAGE UNDER CONSTRUCTION
The name is derived from the Greek words sarkos meaning flesh, and kokkos meaning a berry, a reference to the fleshy fruits. A Genus of slow growing evergreen shrubs, grown for their foliage, fragrant, winter flowers and spherical fruits. Flowers are tiny, the only conspicuous parts being the anthers. Useful for cutting in winter. Fully hardy to frost hardy.
Grow as ground cover in a woodland garden or use as a low informal hedge. Tolerant of atmospheric pollution, dry shade and neglect. They enjoy growing in rich organic soil, moist but well drained, a neutral pH is thought to be best. They are easy to grow but take at least a season to establish and can be successful in containers. Plants are usually produced from semi ripe cuttings in late summer. Do not prune into old wood. RHS pruning group 8.
