Report an issue with this species
Moreton Bay Chestnut is an Australian native tree with a rounded crown, low-spreading branches, and glossy, pinnately-compound leaves, producing showy red and yellow pea-shaped flowers in autumn. It thrives in coastal areas and along riverbanks, providing shade and attracting hummingbirds. This species is suitable for urban environments due to its tolerance to partial shade and light frost, and its strong root system helps with soil stabilization.
