Common gardeners may know the plant as Soap-bark tree. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Quillaja saponaria Common Name: Soap-bark tree Family: Rosaceae Author: Molina. Known Hazards: The plant is toxic if taken internally, tending to dissolve the blood corpuscles[171].
The bark, and possibly other parts of the plant, contains saponins[4]. Although toxic, saponins are very poorly absorbed by the body and so tend to pass through without causing harm, they are also destroyed by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisible not 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[K]. Mature Height: 18 Mature Width: 6 Habitat: Mountainous regions on the western slopes of the Andes[169, 171].
Propagation Notes: Seed - sow spring in a greenhouse. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant out in early summer and give some protection from the cold for at least their first winter outdoors.
