Safety & Hazards

The seeds are toxic[1]. They are used as a fish poison[2]. The fruits and the seeds contain up to 30% emulsifying saponins[1, 3]. Although poisonous, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans. They can be removed by carefully leaching in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them. However, it is not advisable to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[PFAF].

Cultivation Details

HabitEvergreen Tree
GrowthMedium

Succeeds in a sunny position in any well-drained soil[4]. Plants are very tolerant of a wide range of soils, including those that are dry, stony or nutrient deficient[4]. Established plants are very drought tolerant[1]. Tolerant of salt-laden winds[1]. Plants have a moderate rate of growth, able to reach a height of around 2.5 metres within 2 years from seed[5]. The flowers are mostly male, with some female flowers and also some bisexual. The male flowers are produced in great quantities, they seem to fall from the tree almost like rain and litter the ground beneath[6].

Propagation

Seed - best sown as soon as it is ripe in a partially shaded position in a nursery seedbed or in individual containers. A low to moderate rate of germination can usually be expected, with the seed sprouting within 20 - 40 days[5]. When the seedbed-sown seedlings are 4 - 6cm tall, pot them up into individual containers and they should be ready to plant out 6 - 7 months later[5]. The seed stores well even when kept at ambient temperatures and humidity, still germinating satisfactorily after more than 12 months in storage[5]. Greenwood cuttings.
