Pittosporum tenuifolium

Landscaping Uses for Pittosporum tenuifolium in NZ

This versatile tree is a popular option in New Zealand landscaping due to its adaptability and attractive appearance. Pittosporum tenuifolium is frequently used for formal or informal hedges, privacy screens, shelterbelts, and as a lush backdrop for planting schemes. Its ability to thrive in poor soils and exposed locations makes it a top performer in both residential and commercial landscapes. Because of its tidy habit and evergreen nature, it remains a favourite for garden designers looking for structure and year-round interest.

Pittosporum tenuifolium Hedge Spacing

To create a dense, attractive hedge with Pittosporum tenuifolium, The Plant Company recommends planting at 40 to 50 cm spacing. Closer spacing at 40 cm encourages faster fill-in and more upright growth, as the plants compete for light. Wider spacing may lead to gaps at the base and bushier, less uniform growth. To maintain a dense and healthy hedge, annual trimming is recommended, along with planting in a sunny position.

Why Pittosporum tenuifolium Is Called Black Matipo

The name “Black Matipo” reflects the plant’s distinct physical traits. Young stems are often dark grey to black, and its small, deep reddish-purple flowers darken as they age. Additionally, the seed capsules mature to a near-black hue. “Matipo” is a traditional Māori term used to describe various native shrubs and trees, making “Black Matipo” an apt common name for this native species.

Pittosporum tenuifolium Growth Rate

In favourable conditions, Pittosporum tenuifolium grows at a medium to fast rate. It can reach its full height of 10 metres in about 10 to 15 years if planted in warm, sheltered conditions with adequate water and nutrients. In more exposed or dry environments, the growth rate will be slower. This tree is often pruned to maintain a more compact shape or kept at a lower height when used as a hedge.

Best Growing Conditions for Pittosporum tenuifolium

To achieve the best results, Pittosporum tenuifolium should be planted in well-drained soil and positioned in full sun or partial shade. Poor drainage can result in root rot and other diseases, so avoiding waterlogged conditions is critical. This species will tolerate wind, coastal conditions, dry periods, and moderate frost, making it a robust performer in many New Zealand gardens.

Pittosporum tenuifolium Flowers

The flowers of Pittosporum tenuifolium are small—typically around 1 cm in diameter—and range in colour from dark red to almost black. Their sweet, honey-like fragrance is especially noticeable in humid conditions and serves to attract moths and other night-time pollinators. These flowers emerge from lateral buds and often appear singly or in small clusters during spring.

Pittosporum tenuifolium Problems and Solutions

While generally low maintenance, Pittosporum tenuifolium can experience a few issues. The most common problem is root rot, which arises from poorly drained soil. Symptoms include yellowing leaves, wilting, and branch dieback. Ensuring proper drainage and avoiding overwatering will usually prevent this. Another common issue is sparse foliage, especially when planted in deep shade or left unpruned. An annual trim and planting in a bright position will help maintain its density. Pest and fungal issues are rare and generally not a concern for healthy plants.
