Threat: High threat environmental weed.
Description: Erect large shrub or small tree that can spread to 8 metres with bright yellow flowers and flattened leaf structures (phyllodes).
Flowers: Bright, yellow and clustered in dense cylindrical spikes 2–5cm long in axils along branches, flowering late winter to spring.
Fruit: Fairly straight pod 5–15cm long with four to 10 seeds and maturing in late spring to summer.
Leaves: Phyllodes alternate, linear, tapering to blunt tip and more than seven times as long as broad, with two to three obvious parallel veins. There is a gland at the base of the phyllode.
Stems: Smooth angular, green to reddish-green, becoming rounded, woody and grey with age.
Note: Sallow wattle invades heathlands, woodlands, forests, riparian habitats, grassland, coastal dunes, scrub, river systems and catchments. Seeds long lived in soil and regenerate readily after fire.
Control measures: Hand weed, cut and paint or scrape and paint with suitable herbicide.
Dispersal: Ants, birds.
