Pittosporum tenuifolium (P. nigricans) is a handsome, fast-growing, dense, evergreen shrub or small tree with small, glossy green oval leaves on slender, black, erect branches. Small dark purple flowers generally go unnoticed in the spring. Seaside tolerant. Easily sheared and shaped into a hedge or privacy screen. The leaves of the Kohuhu Pittosporum are larger, have a visible midrib and lateral veins, and are not as shiny as Silver Sheen.
