Its shallow rooting depth makes it unsuitable for riverbank stabilisation in situations where bank height likely exceeds the maximum rooting depth (~2 m) of adult trees..
P. tenuifolium and its cultivars are far and away the most widely grown of any species of pittosporum in the UK.
As such they are proven to be hardier than other species.
Once the plants are established and start to develop a woody stem they can certainly withstand temperatures of minus 5\xb.
Pittosporum are prized for their glossy, evergreen leaves and striking dark stems.
Leaves may be various shades of green, yellow, purple or silvery-grey, or variegated, depending on the cultivar.
The flowers are usually small, brown and lightly scented, although some have showy white flowers with a strong fragrance..

Kōhūhū is a relatively fast growing plant growing from 0.5 metres to 3 metres within five years.
The root system is shallow and spread out.
These characteristics make it ideal – when used in conjunction with another plants – for use in stream stabilisation and erosion control..
Pittosporum can be relatively easy to care for, but it is important to understand the conditions they require and to place them in a suitable spot
Most pittosporums are H4 hardyHowever, others, such as P
tobira, are conservatory plants, which must be grown inside over winter – though they may be able to go out over the summer monthsEvergreen shrubs (or small trees), pittosporums are an excellent alternative to boxwoods in warm climates
Fast growing and uncomplaining, pittosporums respond well to clipping, shaping, pruning, and training of nearly any sort
Pittosporum will do best in a sheltered position in full sun or light shade
