Betka bottlebrush is an upright or angular spreading shrub which grows to between 1 and 3 metres in height and 1 to 4 metres in width. It has greybark which reveals white underneath after peeling. Its new growth is initially pink, becoming blue-green and eventually green with a non-glossy sheen. The stiff leaves are irregularly aligned as a result of twisted petioles. The crimson inflorescences appear predominantly between November and February in the species' native range. These are followed by squat, woody fruits which become partially embedded into the stem.
