Coast Coral Tree

Coast coral tree (Erythrina caffra) is a large, semi-deciduous tree in the family Fabaceae, native to the subtropical coastal forests and riparian zones of the eastern coast of South Africa and coastal Mozambique. It grows in coastal dune forest, riverine forest margins, and rocky hillsides near the sea, often becoming a prominent canopy tree in coastal forest. The trunk is covered in distinctive corky, spiny bark; branches are armed with short thorns; and spectacular clusters of bright red, tubular flowers are produced before or with the new leaves in late winter and spring, providing an important nectar source for sunbirds and other nectarivores. Fruit pods are long, woody, and contain bright red seeds. Coast coral tree is widely planted as a street tree, shade tree, and garden specimen across subtropical coastal cities and is the official tree of Durban, South Africa. It is assessed as Least Concern by the IUCN. Historically, various parts of the tree were used medicinally by Zulu and Xhosa communities. In cultivation it has naturalised in Hawaii and other tropical regions.
