Cockspur coral tree

''Erythrina crista-galli'', often known as the cockspur coral tree, is a flowering tree in the family Fabaceae, native to Argentina, Uruguay, southern Brazil and Paraguay. It is widely planted as a street or garden tree in other countries, notably in California. The ceibo is the national tree of Argentina, and its flower the national flower of Argentina and Uruguay.

This species characteristically grows wild in gallery forest ecosystems along watercourses, as well as in swamps and wetlands. In urban settings, it is often planted in parks for its bright red flowers.
