Pittosporum tenuifolium (Kohuhu) - A fast growing dense evergreen upright shrub or small tree that grows to 20 to 30 feet tall. It has glossy medium green oval slightly undulating leaves that are held on dark, nearly black, new stems and dark fragrant purple flowers held in small clusters in the spring that are followed by small orange fruit. Plant in full coastal sun or part shade, with occasional watering. Seaside tolerant. Hardy to 15-20 F. This plant is native to both islands of New Zealand where it is common in the lower mountain forests from sea level up to nearly 3,000 feet. The name Pittosporum comes from the Greek words 'pitta' meaning "pitch" and 'spora' meaning "seed" in reference to the sticky seeds of many members of the genus. The specific epithet tenuifolia is from the Latin words 'tenu' meaning "slender" and 'foli' meaning "leaves" in reference to the more slender leaves of this species. This plant was first introduced in San Francisco (as P. nigra) by sea captain James Walsh, who returned from a trip to Australia and New Zealand (and possibly Japan) in 1865 with many plants that have been in cultivation in California ever since.  This description is based on research and observations of this plant as it grows in our nursery, in our nursery garden and in other gardens that we visit. We also incorporate comments received and appreciate getting feedback of any kind from those who have any additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Pittosporum tenuifolium.
