It grows to 2–10 m tall, and has serrated, sticky green leaves 4–13 cm long and 0.7–3 cm broad, which emit a spicy scent on warm days. The flower's inflorescence is arranged in a spike 0.6–3 cm long, in range of colors from green to red. The fruit is a wrinkled purple berry 4–6.5 mm diameter, with a waxy coating, hence the common name wax myrtle. This species has root nodules containing nitrogen-fixing microorganisms, allowing it to grow in relatively poor soils.
