Notes: | Quick growing, hardy tree suitable for a wide range of situations although prefers well drained spils. Moderately drought tolerant. Germination is very slow, cracking the seed coat or soaking in boiling water for one minute will improve germination. Seed can be stored at room temperature for several years. Cuttings strike readily. The leaves and bark contain saponin and have been used to stupefy fish. Crushed leaves can be used instead of soap. With appropriate mordants it produces red brown or orange yellow dyes. Medicinal uses by Aborigines and early settlers included: bathing sore heads with a solution of the leaves crushed in water, drinking a bark and wood decoction for a tonic, gargling with a bark and wood decoction to relieve toothache, rubbing infusions of bark, roots and wood on the body for aches and pains, chewing young leaf tips to relieve an upset stomach and applying leaves to sore eyes. The timber is pale pink when first cut, changing to orange red with age, strong and fairly durable in the ground. |
