Average Winter night-time temperatures in Winter are much higher near the coast allowing a longer growing season. Annual rainfall in the Brisbane area exceeds rainfall in the natural habitats of Acacia macradenia by around forty to one hundred percent. In more recent years this seems to have lessened or stopped completely.ДЄcacia macradenia is very productive in terms of its seed once planted along coastlines where annual rainfall significantly exceeds its natural habitats.
