Acacia dealbata Link
Silver wattle (Acacia dealbata) is a long-lived, evergreen tree that is native to eastern Australia. It was introduced to New Zealand as a garden ornamental and was first recorded in the wild (naturalised) in 1870. The tree grows up to about 25 metres tall and has smooth grey bark and finely divided, blue-grey foliage. It flowers from July to September, producing pale yellow, ball-shaped flower heads in large numbers, which develop into flat seed pods. It tolerates drought, frost and poor soils. It reproduces by seed and vegetatively by root suckers. Seeds are dispersed by gravity, water, ants and human activities. Seeds can remain viable in the soil for many years and germinate readily following disturbance or fire.
