Pittosporum are evergreen shrubs or small trees. They have thick, glossy, dark grey, leathery leaves. Flowers are rather small and creamy white in colour. At maturity they produce a leathery fruit called a capsule. They are quite tolerant of salt sprays and strong winds common along coastal regions.
They will tolerate full sun and will thrive in shaded areas.
Will tolerate temperatures of twenty degrees F or less without noticeable injury.
Adequate water to keep from drying out. Feeding: General purpose fertilizer.
Pruning and wiring:
The tree has no particular natural form making it a candidate for informal upright.
May be propagated by tip cuttings. Seeds are difficult to obtain and viability is usually poor. Grafting is useful.
The tree needs annual repotting and may be severely root pruned. The soil should be well draining.
Pests and diseases:
Cottony-cushion scale. Spray with agricultural oil.
Species suitable for bonsai:
Pittosporum tobira variegatum - resembles P. tobira in all respects except for its thinner leaves variegated with white.
