Pittosporum tenuifolium 'Silver Sheen' (Silver Sheen Kohuhu) – A fast growing evergreen upright shrub that can grow upwards to 12-15 feet tall (with age to at least 20 ft) with small oval flat silver-green leaves held on thin reddish black branches – the small leaves start uniformly round and elongate with age and the very dark reddish pruple male flowers are not often seen.
Plant in full coastal sun in cooler bay area garden or part shade elsewhere, with occasional watering. Tolerant of windy and near seaside conditionsA very showy and dramatic looking plant when the silver highlights in the leaves catch morning and afternoon light. This is further enhanced if a gentle breeze causes the branches to move, making the plant shimmer.
While this cultivar has notably more open habit and smaller leaves than the species, shearing can keep it dense and we have seen long lived plantings maintained as dense narrow formal hedge from 3 to 6 feet tall with regular tip-pruning. Has proven a problematic in full sun locations in hotter inland locations with summer heat and during the warm summer of 2015 and has even shown stress in coastal climates so we are currently recommending this shrub only be used in part sun locations, even in coastal Southern California gardens.

This information about Pittosporum tenuifolium 'Silver Sheen' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
