Medicinal UsesNone knownOther UsesThe opened seeds can be boiled up to produce a gum. This gum can be used as a safe herbicde on weed seedlings in fragile areas - by smothering the plants.Can be grown as a windbreak hedge in the mildest areas of the country, resisting maritime exposure. Wood. Used in the manufacture of golf clubs. Notes: Native to wet forests in coastal areas between the Great Dividing Range and the sea from southern Victoria to southern Queensland. The fruits are attractive to birds and other animals including posums and foxes. It also spreads in dumped garden waste and contaminated soil and seeds stick to footwear. Sweet Pittosporum is invasive in New Zealand, South Africa and USA. It is a serious weed problem outside its natural range in SA, Tasmania, Victoria and WA. It is a weed on King, Lord Howe and Norfolk islands. It is a serious weed in the Sydney district in areas where it does not occur naturally and on the NSW mid-north coast.Pittosporum undulatum, commonly mistaken as a native in Tasmania, appears to hybridise with P. bicolor in Tasmania. It is invasive in coastal areas. Control of dispersal is difficult. Pittosporum affects natural environments through shading, competition and changes in soil nutrients. Changes in fire regimes has allowed Sweet pittosporum to out-compete fire-adapted native species. References: |
