Pittosporum tenuifolium, also commonly called Silver Sheen or Silver Sheen Kohuhu, is an evergreen shrub that is hardy in U.S. Department of Agriculture plant hardiness zones eight through 11. This upright-growing shrub has small, silvery-green leaves that give it a shimmering appearance in the sunlight. It blooms with purple flowers in spring and typically grows 15 to 20 feet tall and 6 to 8 feet wide.
Plant Silver Sheen in areas with partial to full sun exposure – three to six or more hours of sunshine per day. Water the plant regularly, particularly during its first growing season, to help encourage deep root formation. Prune Pittosporum tenufolium Silver Sheen by shearing it into shape every year. Additionally, gardeners should fertilize it annually in early spring before any new growth emerges with a balanced, all-purpose fertilizer.
With its attractive foliage, slender black stems and open growth habit, Silver Sheen is ideal for use as a formal hedge, either by itself or in a group of multiple shrubs. When deciding on a planting location, keep in mind that it is a relatively fast-growing shrub that can be maintained at heights of 3 to 6 feet if it is tip-pruned on a regular basis.
