Spreading tree to 6-10 m high. Leaves bipinnate, usually bluish green. Flowers in small heads, golden-yellow, appearing Jul-Sep. Moderately frost hardy. This has been a very popular wattle in the past but it is now regarded as undesirable in many areas because of its invasive nature. Frequently planted in south-eastern Australia.

Acacia doratoxylon (Brown Lancewood)

Native to New South Wales, Australian Capital Territory and Victoria

Usually a rounded tree to 10 m high and about the same across. Phyllodes long and narrow, 8-20 cm long and 0.2-1.0 cm wide. Flowers in spikes 2-3 cm long, bright yellow, appearing Sep-Nov. Moderately frost hardy. A slow-growing species suitable for most parts of south-eastern Australia.

Acacia longifolia [includes Acacia sophorae ] (Sydney Golden Wattle, Coast Wattle)

Native to South Australia, Queensland, New South Wales, Victoria and Tasmania.

Erect or spreading tree up to 10 m high and as much as 25 m across in exceptional cases. Phyllodes elliptical, lanceolate or narrow-lanceolate, 5-25 cm long and 1.0-3.5 mm wide. Flowers in spikes 2-5 cm long, golden yellow, appearing Jun-Oct. Moderately frost hardy. This is a species which has been planted in many regions in south-eastern Australia and is often a nuisance. It has become a weed in some places overseas. Particularly suitable for coastal planting.

Acacia acuminata (Raspberry Jam Wattle)

Native to Western Australia

Small tree up to nearly 12 m high or a shrub. Phyllodes long and narrow, from 8-20 cm long and 2-8 mm wide. Flowers in spikes; deep yellow. Moderately frost hardy. Suitable for small gardens in south-western Western Australia and south-eastern Australia, particularly sandy areas.

Acacia falciformis (Broad-leaved Hickory Wattle, Mountain Hickory)

Native to Queensland, New South Wales, Australian Capital Territory and Victoria

Erect tree up to 12 m high. Phyllodes lanceolate or narrow-lanceoate, 8-20 cm long and 2-6 cm wide, sometimes falcate, usually conspicuously grey-green. Flowers in globular heads, pale yellow, appearing Oct-Dec and sometimes other months. Moderately frost hardy. A very hardy tree and suitable for planting in well-drained exposed rocky places in temperate regions.

Acacia aulacocarpa (Brush Ironbark Wattle)

This is a recently described species. Usually an erect tree up to 10-15 m high. Phyllodes usually obovate, 4-8 cm long and 1-3 cm wide, bluish green. Flowers in globular heads, creamy yellow, usually appearing Oct-Nov but sometimes at other times of the year. Moderately frost hardy. Excellent garden subject on account of its foliage. Suitable for south-eastern Australia and particularly limestone sites.

Tree up to 25 m high in its native habitat. Leaves bipinnate, large and bluish green. Flowers in large globular heads, golden yellow, appearing Sep-Oct. Moderately frost hardy.
