Cultivation Details

A plant of mainly subtropical areas, just moving into the tropics in eastern Australia, where it is found at latitudes from 37 - 21°S[]. It grows at elevations from sea level up to 300 metres[]. It grows best in areas where annual daytime temperatures are within the range 18 - 28°c, but can tolerate 10 - 38°c[]. Mature plants can be killed by temperatures of -5°c or lower, but new growth is badly damaged at 0°c[]. It prefers a mean annual rainfall in the range 800 - 1,000mm, but tolerates 600 - 1,200mm[].
Prefers a sunny position in a light to medium, well-drained soil[]. Prefers a pH in the range 5.5 - 6.5, tolerating 5 - 7[]. Established plants are drought tolerant[].

Edible Uses

None known

Medicinal

The resin from the trunk is astringent[]. It is used in the treatment of diarrhoea[].

Agroforestry Uses:

The tree only flowers vigorously once every few years, but when it does it is an important source of pollen and yields a fairly pale honey of minor importance[].

Other Uses

An astringent resin, known as kino, is obtained from the trunk[].

The heartwood is a light pinkish-brown; the sapwood pale and up to 5 cm wide. The wood is moderately close-textured, with a rather interlocked grain, it is of moderate strength, very hard but not durable[]. It is used for rough flooring, slabs, fence rails, palings and hardboard[].
The wood is used for fuel[].

Propagation

Seed - best sown as soon as it is ripe, though it can be stored. Sow in a fairly sunny position in a nursery seedbed. When large enough to handle, prick the seedlings out into individual pots and grow them on in a sunny position until large enough to plant out.
Cuttings of mature wood of the current seasons growth in sandy soil.
