Report an issue with this species

Acacia baileyana is a graceful shrub or small tree known for its fern-like, bipinnate leaves and showy bright golden-yellow spherical flowers, blooming in winter and spring. Native to a restricted area of New South Wales, it thrives in well-drained, stony or clay loamy soils. While widely cultivated as an ornamental, it can become an invasive environmental weed outside its native range.
