What to Eat

Edible parts: Leaves, Caution

Leaves can be cooked and eaten, though this is a famine food used only as a last resort. Some caution is advised given the plant's toxicity.

Known Hazards

The seed and leaves are poisonous, containing saponin-like substances. 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 the seed or flour 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.

Where to Find It

It is a temperate plant. It is drought and frost resistant. It adapts to most soils. It will grow best in soils that are not too fertile but are well drained and in a sunny position. Plants are hardy to -15°C. Tasmania Herbarium.
