Perth’s tallest wattle can grow to 10 m although frequent fires will restrict its growth. It is found near the coast on sand or limestone, and through underground stems it forms clumps and thickets. The thickets have a pleasant scent, especially in summer. Flowering occurs in late winter or spring. The species name comes from Latin: rostellum “small beak” and ferre “to bear” and alludes to the beaked phyllodes (“leaves”).
