Sweet Pittosporum Overview

Pittosporum undulatum is a rounded, dense tree which can grow to 15m tall. It has wavy (undulating) leaf edges and carries bright orange woody fruits - about 1cm in diameter - after flowering in spring or early summer. The flowers are fragrant, bell-shaped and creamy white. It is sometimes also known as Sweet Pittosporum, Native Daphne, Australian Cheesewood, Victorian Box or Mock Orange. Pittosporum undulatum is fast-growing and although this can be useful in some spacious rural or urban settings, it can be invasive - and has become a problem for this reason, in several parts of the world, including South Africa, Australia and the USA. Cheesewood is widely tolerant so it will grow in most moist or wet soils - withstanding some dry periods - but it shouldn't be planted near water sources where seed pods can get caught by the current and get carried to new locations, nor close to wild areas.
