Quick Summary

The term "wheel tree" can refer to two different plants. One is Trochodendron aralioides, an evergreen tree native to East Asia. It is known for its flowers, which have a characteristic ring of stamens resembling a wheel, giving the plant its common name. These flowers lack sepals and petals and are either male or bisexual.1

The other plant referred to as a wheel tree is Stenocarpus sinuatus, an Australian tree cultivated for its ornamental value. This tree is also noted for its circular clusters of bright red to orange-scarlet flowers. Both plants are sometimes cultivated as ornamentals.21
