Pittosporum Tenuifolium: A Versatile Evergreen Shrub
Introduction
Pittosporum tenuifolium, known as Kohuhu in New Zealand, is a fast-growing evergreen shrub with glossy, crinkled leaves. Its tiny bell-shaped flowers and blackish seeds add a touch of interest to the plant. Pittosporum tenuifolium is a popular choice for borders, screening, hedging, and even flower arrangements.
Growing Conditions
This adaptable shrub can thrive in full sun or partial shade and any reasonably fertile soil. It’s important to avoid planting in areas exposed to cold winds or waterlogged ground. Mulching with compost in early spring can help improve soil health.
Planting
Plant Pittosporum tenuifolium in spring or autumn. Improve poor soil by adding organic matter before planting. For pots, use a soil-based potting compost.
Care
Water regularly during the first growing season to establish the root system. Once established, Pittosporum tenuifolium requires minimal care. Trim as needed from spring to mid-summer to maintain desired size and shape.
Propagation
Propagate Pittosporum tenuifolium by cuttings, seed, or layering. Semi-ripe cuttings can be taken in mid to late summer, while seeds can be sown in small pots in spring. Layering involves rooting stems while still attached to the parent plant.
Pests and Diseases

Buying Tips
When buying Pittosporum tenuifolium, ensure plants are healthy and growing vigorously. Overgrown or ‘pot-bound’ plants should be avoided. Variegated or colored foliage varieties are available for a more compact and slower-growing option.
