About Callicoma serratifolia Andrews
Callicoma serratifolia Andrews, commonly called black wattle, can reach up to 20 meters tall in its natural growth. When grown in cultivation, it more typically grows to between 6 and 10 meters tall, with a 3-meter spread. It produces lanceolate or elliptic leaves that grow up to 12 cm long and 5 cm wide, with coarsely serrate margins. The upper leaf surface is dark green, while the lower leaf surface is white, covered in fine white hairs. Pale-yellow, globular flower heads emerge in late spring and early summer, which falls between November and December in Australia. These flower heads average 1.5 cm in diameter and are attached to stalks 1 to 2 cm long. This species grows within and on the edges of rainforest in near-coastal areas of New South Wales and southeast Queensland, where it is found mostly along drainage lines or near creeks.
