Eucalyptus marginata
Also called Bastard Mahogany
Jarrah is a large, long-lived eucalypt from south-west Western Australia, valued for its hard timber. It is a tree for open ground rather than pots, and it resents waterlogging and dieback-prone conditions.
Eucalyptus marginata, commonly known as jarrah, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a tree with rough, fibrous bark, leaves with a distinct midvein, white flowers and relatively large, more or less spherical fruit. Its hard, dense timber is insect resistant although the tree is susceptible to dieback. The timber has been utilised for cabinet-making, flooring and railway sleepers. It is known as djarraly in Noongar language and historically as Swan River mahogany.
Eucalyptus marginata occurs in the south-west corner of Western Australia, generally where the rainfall isohyet exceeds 600 mm (20 in). It is found inland as far as Mooliabeenee, Clackline and Narrogin and in the south as far east as the Stirling Range. Its northern limit is Mount Peron near Jurien Bay but there are also outliers at Kulin and Tutanning in the Pingelly Shire. The plant often takes the form of a mallee in places like Mount Lesueur and in the Stirling Range but it is usually a tree and in southern forests sometimes reaches a height of 40 metres (130 ft). It typically grows in soils derived from ironstone and is generally found within its range, wherever ironstone is present.
Jarrah timber is mainly used for cabinet making and furniture, although in the past it was used in general construction, railway sleepers and piles. In the 19th century, famous roads in other countries were paved with jarrah blocks covered with asphalt.
