Growth characteristics Fast-growing. Coppices root-suckers. Tolerates a variety of acid to slightly alk; soils from sands to clay. Frost-tolerant. Inland high alti provenances are more frost-tolerant than lower elevatio coastal provenances. No insect damage reported in South Wales. Medium susceptibility to brown swan-leaf beetle in southern Queensland. Tolerates drought, periodic waterlogging and flooding and moderately siii^. soils. Can tolerate strong winds. Performs well u irrigation (northern Victoria). Exhibits substantial inter-intra-provenance variation for a wide range of attril (e.g. for growth, frost tolerance, salt tolerance). Beet chlorotic on calcareous soil. Moderately salt-tole Expect reduced growth at ECe ca. 5-10 dS/m and red survival above ca. lOdS/m.
Description Medium to tall tree (10-35 m), erect single stemmed. Bark is dark grey, hard, deeply furro Foliage is persistent to ground level. Leaf'teeth' in whor 8-10 carried on thin dark-green branchlets (10-15 cm 1 with small internodes.
