Stenocarpus sinuatus, the Firewheel tree, is a medium to large Australian rainforest tree. It is evergreen with ornamental red circular flowers in summer. It can grow to 30 metres tall, but will be smaller in cultivation and in cooler temperatures. Originates in subtropical to tropical climates, but will also grow in temperate areas.

Will do best in rich loamy soil, but will grow in most soil types. Grow in sun to part shade. Propagation is from seeds, also from cuttings.
