General Biology. Growth form. Tree.
Reproduction. Root suckers. Time to first flowering. 6+
years. Toxicity. Inner bark, root sprouts and wilted leaves are toxic
to humans and livestock. Vegetative regeneration strategy. Resprouts,
produces root suckers. Woody structure. Ring porous. Fire
response. Can resprout vigorously following fire.
Notes. Intolerant of shade. Increases available soil
nitrogen facilitating invasion of other weeds.
Additional information. Origin. Eastern North
America. History of use/introduction. Garden escape.
Suggested method of management and control. Hand pull
seedlings. Basal bark older plants using 250 ml Access® in 15 L of diesel to
base 50 cm of trunk in spring-summer. Read the manufacturers' labels and
material safety data sheets before using herbicides. For further information
consult the Australian
Pesticides and Veterinary Medicines Authority to determine the status of
