The firewheel tree takes its name from the configuration and color of the inflorescences in which the small flowers have a wheel-like arrangement. It is one of Australia's most spectacular trees. S.sinuatus occurs in nature as a large tree but it is usually smaller in cultivation, particularly in cooler areas. The dark, glossy green leaves may be entire or lobed and up to 1.5 ft long. The conspicuous flower clusters are seen in summer through to autumn.
Despite its sub-tropical to tropical origin, S.sinuatus is adaptable to a range of climates and will even succeed in dry climates if additional water is available. It prefers fairly rich, loamy soils but is tolerant of most well drained soils. It may be grown in a sunny or partly shaded location.
