Pittosporum is an evergreen shrub with delicate slender leaves. Commonly grown in UK gardens in the UK are variations of Pittosporum tenuifolium.

In terms of size, Pittosporum range from compact varieties, such as P. Tom thumb around .5m to taller varieties such as Pittosporum tenuifolium 'Silver Queen' around 4m. Most varieties of P.tenuifolium such as Gold star, P. Variegatum are a good garden size of around 2m. 

Most of the P.tenuifolium are H4 or H5, which is hardy in most places in the UK, but Pittosporum will not thrive in cold spots and dislikes chilly winds. To achieve this hardy rating, Pittosporum needs to be planted in well-drained soil and will not tolerate damp or wet winter conditions. If very cold conditions are forecast, - 8 and below, it may be necessary to cover with a fleece, especially when the shrub is young.

Pittosporum will tolerate light or partial shade, although the varieties with dark or variegated leaves produce the best leaf colour in full sun.

Some varieties are scented such as Pittosporum tenuifolium 'Golf Ball' Pittosporum tenuifolium 'Gold Star' Pittosporum tenuifolium 'Tandara Gold all have small sweet honey scented flowers.


Pittosporum is a neatly shaped compact shrub, which is ideal for a mixed garden border. I took the image (left)  in the winter at RHS Harlow Carr. The fact that a Pittosporum was growing in northern garden (close to Harrogate,) shows that in the right growing conditions, good dry soil and sheltered, Pittosporum is reasonably hardy .  

Pittosporum can be clipped into an informal hedge and are ideal for coastal gardens.

How to prune Pittosporum

Pittosporum is an easy to grow shrub, almost maintenance free as it does not really need pruning. Usually it has a naturally neat conical shape. Pittosporum can be tidied up with a light prune undertaken between April and July if needed.  

Green wheelbarrow

Definitely a green wheelbarrow plant requiring very little attention or maintenance.
